REGAL Ejector Check Valve Assemblies - Chlorinators to prevent water from backing up into the various chlorinator or sulphonator system components (FLOODING) when ejector vacuum is

These instructions provide installation and serviceprocedures for all REGAL Chlorinator ejectors to 2,000PPD, all REGAL Sulphonator ejectors to 500 PPD, andall REGAL Ammoniator ejectors to 100 PPD. The typicalinstallation drawings used in this Instruction Bulletinare meant as a guide only. They are general in natureand may not depict the specific REGAL ejector furnishedwith your system.

All REGAL ejectors contain one or two check valvedevices to prevent water from backing up into thevarious chlorinator or sulphonator system components(FLOODING) when ejector vacuum is lost due to normal

(or non-normal) system shut down. To assure floodingdoes not occur under these circumstances, routinemaintenance of the check valve(s) is necessary. Thefrequency of needed servicing depends on the cleanlinessof the water used to operate the ejector, the cleanlinessof the chemical source and therefore the internalcleanliness of the chlorinator system components, thefrequency of ejector cycling (ON/OFF), and the pressuresthe ejector operates against.

It is your (the customer’s) responsibility to establish andundertake a SCHEDULED MAINTENANCE PROGRAM.SEE SECTION 5.0 IN THIS MANUAL.

QUALIFYING STATEMENT

These instructions pertain to all REGAL Chlorinatorejectors to 2000 lbs./day, all Sulphonator ejectors to 500PPD, and all Ammoniator ejectors to 100 PPD. The photosand drawings used in this bulletin are general in natureand may not depict the specific REGAL ejector furnishedwith your system. REFER TO THE REGAL EJECTORPARTS LIST DRAWINGS IN THIS BULLETIN FORCORRECT PART AND ASSEMBLY NUMBERS.

1.1 The check valve in the ejector is designed in such a manner that the ejector may be installed in any position.

NOTE: If high pressure ejectors are to be used in low pressureinstallations (>20 psig), it is recommended that the ejectorbe installed so the vacuum tube connector points downwardso gravity can help provide an effective, watertight seal ofthe check valve. A SECONDARY CHECK VALVE SHOULD BECONSIDERED IN THESE INSTANCES. (Photos No. 12 and 13).

1.2 The point of injection should be carefully chosen so thatthe water pressure at this point is as low as possible.Water supply pressure to the nozzle MUST be highenough to overcome total system back pressure. REFERTO APPLICATION BULLETIN 1002.

1.2.1 All REGAL low pressure ejector assemblies aredesigned for total system back pressures up to20 psig.

1.2.2 All REGAL high pressure ejector assembliesare designed for total system back pressuresfrom 20 psig to 200 psig as standard.

1.3 Generally, the amount of water (GPM) required to operatethe ejector depends upon the chemical flow ratesneeded (lbs./day or gms./hr). The higher the chemicalflow rate, the greater the water flow needed. REFERTO APPLICATION BULLETIN 1002.

1.4 The water supply pressure needed to create the necessaryoperating vacuum is dependent upon the pressure intowhich the chemical solution is injected. Therefore, it isimportant that the minimum pressure differential andwater flow for your installation be determined prior toinstallation and start-up. REFER TO APPLICATIONBULLETIN 1002.

1.5 Follow these steps for installing close-coupled diffuserand ejector.

1.5.1 Unscrew the diffuser from the assembly. DONOT install the diffuser when assembled asdamage to component parts may occur.

1.5.2 Put Teflon pipe thread tape on the 3/4" pipethreads and screw the diffuser into the pipe.These are high-impact plastic parts, but like allplastic pipe fittings, care should be exercisedin tightening. Tighten carefully with properlyadjusted wrench. See Photo No. 1.

NOTE: Make sure the diffuser outlet holes are in the mainstream. The end of an open type diffuser should not allowstrong chlorine or sulfur dioxide solution to come in contact withthe wall of the pipe or fittings as serious corrosion will result.See Photo No. 1.

1.5.3 Place a gasket into the recess on each side ofthe check valve body. Insert the nozzle throughthe check valve body (See Photo No. 2). Holdthe check valve body against the diffuser at1/8 turn COUNTER CLOCKWISE from its finalposition. See Photo No. 3. The check valve maybe installed in any position (up, down, sideways).

1.5.4 Screw the nozzle into the diffuser by hand untilcontact is made against both gaskets. Turn thecheck valve body and the nozzle, at the sametime, 1/8 turn clockwise to the final, tight position.See Photo. No. 3.

1.5.5 Attach water supply hose (or pipe) and tightenclamps. See Photo No. 4.

1.6 Other types of diffuser and ejector installations are possibledepending on the needs of the installation. See DrawingsNo. 1 and 2.

1.6.1 Sometimes, the ejector assembly is mountednear the gas feed system components. In thisinstance, a wall mounting bracket for the ejectorcan be provided, and the ejector outlet can besupplied with various size adapters for solutionhose or pipe.

1.6.2 If the ejector is to be remotely installed with solutionpipe or hose running to the point of application,be certain to cut off the tip of the diffuser beforeinstalling into the pipe or hose. FAILURE TODO THIS WILL RESULT IN EXCESSIVEBACK PRESSURE CAUSING LOSS OFOPERATING VACUUM.

1.6.3 The entire ejector assembly may be submersedin an open channel or tank.

1.6.4 Special diffuser outlets can be used with PVCball valves. See Drawings No. 1 and 2.

1.0 INSTALLATION OF EJECTORS TO 500 PPD (See Photos No. 1, 2, 3 and 4)

2.1 The check valve in the ejector is designed so that theejector may be installed in any position. The check valveassembly, components, and piping MUST be supportedto prevent breakage due to water hammer, vibration, etc. A horizontal mounting of the ejector is preferred.

2.2 The point of injection should be carefully chosen so thatwater pressure is as low as possible. Vacuum is createdin the ejector by the nozzle so water pressure to thenozzle must be high enough to overcome the backpressure and create a strong jet in the nozzle.

2.3 The standard ejector is designed to withstand staticback pressures up to 70 psig (4.9 kg/cm2).

2.4 Generally, the amount of water (GPM) required to operatethe ejector depends on the chemical feed rate (lbs/24 hrs.or kg/hr). The higher the chlorine feed rate, the greaterthe water flow needed. REFER TO APPLICATIONBULLETIN 1009 IN THIS MANUAL.

2.5 Ejector water supply pressure must be greater than thepressure into which the chemical solution is injected.The amount of pressure differential may vary with theapplication. Generally, the greater the pressure into whichthe chemical will be injected, the greater the differentialpressure must be. However, the minimum pressuredifferential and water flow for your installation should bedetermined prior to installation and start-up. REFER TOAPPLICATION BULLETIN 1009 IN THIS MANUAL.

2.6 Follow these steps for installing the ejector assembly.

2.6.1 The nozzle (water) inlet and throat (chemicalsolution) outlet connections are 2" NPT for usewith customer furnished fittings, flanges, unions,etc.

2.6.2 The ejector chemical gas inlet connection is1" NPT.

2.6.3 Use teflon tape on all threaded connections.Tighten threaded connections carefully, usingproperly sized wrenches, and being careful notto over tighten, as damage to the parts could result.

0/2000 P

3.1 For most 500 PPD and below ejector applications, theejector water supply line should be brought to within 3'-5'of the nozzle using rigid pipe materials.

For most 1000/2000 PPD ejector applications, the waterand solution lines will be rigid sch. 80 PVC pipe.

3.2 Shut-off valves, unions, y-strainers, gauges, etc., are valuableservice tools and are recommended. See Drawing No. 1.

3.3 For 500 PPD and below ejectors, connect a flexiblehose line between the rigid incoming ejector watersupply line and the ejector nozzle. Clamp the hosesecurely at both ends with single or double clamps. SeePhoto No. 4.

4.1 The ejector, with its water supply and solution lines orpiping must be properly installed and operating beforechecking the chlorinator, sulphonator or ammoniator.

4.2 Unless the ejector is creating a vacuum, the chlorinator,sulphonator or ammoniator WILL NOT work. Followthese steps:

4.2.1 For 500 PPD and below ejectors, disconnectthe vacuum tubing at the ejector fitting. For1000/2000 PPD ejectors, unscrew the 1" PVCunion at the ejector vacuum connection.

4.2.2 With the booster pump running or the pressurizedwater supply connected, open the ejector waterline supply valve and any other valves that mayexist between the ejector outlet and the point ofchemical application. The ejector should now bein operation and creating a strong vacuum.

4.2.3. For 500 PPD and below ejectors, check forproper vacuum by placing your finger againstthe vacuum tubing connector opening. For1000/2000PPD ejectors, place your hand overthe vacuum union opening.

A STRONG VACUUM SHOULD EXIST. If thereis no vacuum or only a weak vacuum, be certainthat water supply pressure and flow is sufficientand that the nozzle and piping is not plugged.CORRECT THE CONDITION AND OBTAINPROPER VACUUM BEFORE PROCEEDING.

4.2.4 Shut off the water supply to the ejector andmake sure no water comes out of the vacuumtubing connector. If water is observed leakingpast the check valve, correct before proceeding.Once the problem is corrected, cycle the ejectoron and off a few times to make sure the checkvalve is tightly sealed. Water leaks at this pointCANNOT be tolerated.

4.2.5 Reconnect the vacuum tubing or piping to theejector fitting.

PREVENTIVE MAINTENANCE SCHEDULE REGAL SYSTEMS AND SYSTEM COMPONENTS

The best, most cost effective, and easiest way to assure thatyour gas feed system and equipment will provide continuous,dependable, trouble free operation, is to establish a PREVENTIVEMAINTENANCE SCHEDULE. This will assure minimumunscheduled down time. The maintenance schedule should bein writing and include as a minimum, the date of installation,the scheduled date of maintenance, the actual date themaintenance was performed, the parts used, and any applicablenotes.

All REGAL products are engineered for easy maintenance andthis manual provides step by step procedures to properlyservice and maintain each component within the system. It isyour, (the customer’s) responsibility to establish and undertakea SCHEDULED MAINTENANCE PROGRAM.

To support this program, we have available a variety of“REPAIR KITS” containing the parts we feel you may need forminor emergency repairs. We recommend that these kits beavailable in your stock at all times. When this kit, or any partsare used, the kit should be replaced immediately. This manualcontains complete parts lists for each system component.As such, you can order and stock additional parts as deemednecessary.

AT A MINIMUM, THIS EQUIPMENT SHOULD RECEIVESCHEDULED MAINTENANCE AT LEAST ONCE A YEAR.Depending on the installation, application, location ofcomponents, quality of gas, etc., this equipment may needscheduled maintenance more than once a year. This issomething that needs to be determined on a job by job basis.

Spare parts and/or repair kits may be ordered directly from thecompany who supplied your equipment, or they may beordered directly from our inventory in Stuart, Florida.

IMPORTANT: Maintenance on REGAL Systems or SystemComponents should be performed by competent personnelfamiliar with this type of equipment such as; authorizedREGAL Dealers or, Chlorinators Incorporated themselves.

WARNING: Even if the gas feed rate drops to zero as evidencedby the position of the ball or float in the metering tube and/orthe out of gas indicator, and even if the supply containerappears to be empty, SOME LIQUID CHEMICAL MAY STILLBE LEFT IN THE CYLINDER OR CONTAINER.

NEVER disconnect the vacuum regulator from the cylinder orcontainer/manifold valve until ALL cylinder, container, or manifoldvalves are FULLY CLOSED or a highly dangerous chemicalleak causing severe injuries or death could occur.

CYLINDER AND CONTAINER VALVES ARE ALWAYSCLOSED BY TURNING THE VALVE STEM IN A CLOCKWISEDIRECTION.

GENERALA check valve is installed in the ejector to prevent water frombacking into the gas feed system components when the ejectoris shut off. If dirt or impurities from the chemical source, or fromthe water supply line lodge between the check valve and itsseat, water will back into the system requiring cleaning orreplacement of the check valve components.

IMPORTANT: The photos and drawings in this instructionbulletin should be viewed and used with this procedure asnecessary.

f. Examine the check valve seat sealing surfacefor deposits, and clean with denatured alcohol.

g. Check the seat sealing surface with a straightedge to be certain it is completely flat. If thecenter is slightly raised, you will see light underthe straight edge, or it will “rock” over thecenter. If the seat sealing surface is not flat,use a very fine sandpaper or emery cloth on a flat surface (e.g., plate glass) and gently movethe check valve seat in a figure 8 pattern(Photo 6). Do not rub back and forth, or theseat will become distorted.

h. Using a new E-250, wet the tip of the newcheck valve with a very light film (make shinyonly) of Vaseline or Dow Corning DC33. Put the tip of the check valve in the “center” checkvalve seat hole and, using the handle of ascrewdriver or other rounded object, pushagainst the center of the check valve untilthe tip snaps into the seat (Photo 7). DO NOTTWIST THE CHECK VALVE OR DAMAGEMAY OCCUR.

i. Using a “spanner” wrench in the holes locatedin the underside of the outlet body, unscrewthe outlet body from the clamping ring. Donot lose the spring or the diaphragm assembly.

1) The diaphragm is made from a specialcorrosion resistant plastic. Inspect it carefullyfor nicks or cuts. Replace as necessary.

2) The check valve action is accomplishedby the diaphragm bolt sealing tightly onthe o-ring located in the center of theinlet body when the ejector is shut off.As such, the diaphragm bolt sealingsurface and the o-ring must be free of dirtor impurities that may prevent an effectiveseal. Clean all parts or replace as necessary.Always use a new check valve seal o-ring.

j. Reassemble, using a spanner wrench inholes, located in underside of outlet body.Tighten outlet body and clamp ring.

k. When reinstalling the check valve assemblyin ejector, put a thin film of Vaseline or DowCorning DC33 on the seat o-ring and seatgasket for lubrication. Use very sparingly(make it shiny only). DO NOT USE ANY OTHERPETROLEUM BASED GREASES OR OILS.

5.4.6 Inspect the o-ring S-418 located on the E-554poppet and replace as necessary. THIS IS THESECONDARY CHECK VALVE SEAL AND MUSTBE IN LIKE NEW CONDITION.

5.4.7 Inspect and clean as necessary the flat surfaceinside top body E-551. Since this is the sealingsurface for the S-418 sealing o-ring, THIS SURFACEMUST BE CLEAN AND PERFECTLY FLAT.

5.4.8 The primary check valve is located inside bottombody E-552. To gain access to the primary checkvalve, proceed as follows:

a. Using Drawing A-950/A-949 as a guide, carefullyunscrew (counter clockwise) the spring/ballretainer E-553 from bottom body E-552. THEOUTER CIRCUMFERENCE OF THESPRING/BALL RETAINER IS KNURLEDTO MAKE IT EASIER TO UNSCREW.

ONCE REMOVED, THE BALL E-556 IS FREETO FALL OUT. BE CAREFUL NOT TO LOSEOR DAMAGE THE BALL.

b. Inspect the ball E-556 and make sure it isfree of all deposits, nicks, and pits. If in doubt,replace as necessary.

c. Poppet E-553 contains two o-rings. The S-415o-ring is a sealing o-ring and MUST remainin its groove when reassembling the checkvalve components. Inspect this o-ring for wearand replace as necessary.

d. The second poppet o-ring S-417 is a criticalo-ring as it is the sealing surface for theprimary check device (ball E-556). This o-ringis located in an undercut groove at the baseof spring/ball retainer E-553.

If o-ring S-417 shows any signs of wear or, ifo-ring S-417 is flattened due to the check actionof ball E-556, replace with a new one.

5.4.9 Clean all check valve parts with warm waterand/or a mild solvent such as denatured alcohol.

5.4.10 Make sure all parts are thoroughly dry and allo-rings are in place and reassemble by reversingthe steps outlined in Section 5.4.

5.5 EJECTOR CHECK VALVE 1000/2000PPD -CLEANING OR REPLACING (Refer to Drawing A-2920/2922)

5.5.1 A-2000 CHECK VALVE

A check valve is installed in the ejector assemblyto prevent water from backing into the systemwhen the ejector is shut off. The check valvedesign is such that it is extremely difficult for dirtto lodge under the valve, but it might, if largeamounts of sand or other impurities are presentin the water supply; and dirt could possibly enterfrom the chemical side. To remove and cleanthe valve, proceed as follows:

a. Close the manifold valve that the vacuumregulator is attached to before working onany system components.


c. Open the 1˝ PVC vacuum union MS-19 byunscrewing (counter clockwise) the unionring and move the vacuum piping out ofthe way. Be careful not to lose the vacuumunion o-ring.


d. Using Parts List Drawing A-2000 as a guide,unscrew clamp ring CV-2004 and lift the topbody CV-2002 with clamp ring off bottombody CV-2001 and set aside. BE SURE NOTTO LOSE O-RING S-804.

e. Carefully lift out poppet CV-2003 andspring CV-2005.

f. Poppet CV-2003 contains an o-ring S-805which is the check valve seal. THIS O-RINGMUST BE IN PERFECT SHAPE, FREE OFNICKS, CUTS, ETC. IF NECESSARY,REPLACE IT WITH A NEW ONE.

IF O-RING S-805 SHOWS SIGNS OF BEINGFLATTENED DUE TO THE ACTION OFTHE CHECK VALVE, REPLACE IT WITH ANEW ONE.

g. Inspect the flat surface inside top bodyCV-2002 to be sure it is flat and clean. THISIS THE SURFACE O-RING S-805 SEALSAGAINST.

h. Clean all check valve parts with warm wateror a mild solvent such as alcohol and drythoroughly.

i. Reassemble the ejector check valve assemblyby reversing steps “a” through “e”.

5.6 CLEANING/INSPECTION OF EJECTORNOZZLE TO 500 PPD5.6.1 To remove the ejector nozzle for cleaning, the

water pressure in the main must first be shut offunless the ejector was initially installed with a valveon the inlet side and a ball valve or corporation stopin the outlet, so that isolation of the ejector is possible.

a. Close the cylinder/container/manifold valve(s)before working on any system component.

5.6.2 Remove the ejector supply hose and gas vacuumtubing from the ejector assembly.

5.6.3 Rotate the complete ejector body counterclockwise,making certain that the solution diffuser remainsfixed in the solution piping or main. (Photo 1).

5.6.4 Unscrew the nozzle from the ejector body.Check the gaskets located in each side of thebody and replace if necessary. (Photo 3).

5.6.5 Nozzle plugging can be caused by:

a. A piece of foreign material (pipe sealer, stone,or dirt) lodging in the nozzle orifice. This canusually be blown out in the reverse direction.DO NOT USE SHARP TOOLS OR ALTERTHE SIZE OF THE ORIFICE IN ANY WAY.

b. Excess plastic pipe solvent or glue used duringinitial installation running into the orifice areaof the nozzle. If this cannot be cleaned outeasily, the nozzle may need to be replaced.

c. Build-up of deposit. This could be a chemicalbuild-up or iron, manganese, or some othermaterial which usually can be removed byimmersing the nozzle in muriatic acid and rinsing.CAUTION: READ ALL WARNING LABELSON THE MURIATIC ACID CONTAINER, ANDAVOID SKIN CONTACT. It is recommendedthat safety goggles or face shield be usedwhen working with any strong acid. Somewaters are such that build-up of deposits cancause an ejector to become inoperative in ashort period of time.

5.6.6 To reinstall the nozzle:

a. Insert the nozzle through the ejector bodyand screw into the solution diffuser. Makesure the gaskets are in place and in goodcondition. (Photo 3).

b. Hold the ejector body against the diffuserat 1/8 turn counterclockwise from its finalposition. (Photo 3).

c. Screw the nozzle into the diffuser by handuntil contact is made against both gaskets.

d. Turn the ejector body and the nozzle at thesame time, 1/8 turn clockwise to the finaltight position. THE PARTS ARE PLASTIC,AND EXCESSIVE TIGHTENING MAY CAUSEBREAKAGE. DO NOT USE TOOLS.

e. Reinstall the ejector supply hose and vacuumtubing. (Photo 4).

5.6.7 Open all valves and check for proper operatingvacuum.

5.7 CLEANING / INSPECTION OF1000/2000 PPD EJECTOR NOZZLE 5.7.1 The ejector nozzle and throat thread into the

ejector body. To inspect and clean these parts,proceed as follows:

a. Close the manifold valve that the vacuumregulator is attached to before working on anysystem component.

b. Shut off the water supply pressure to theejector, and close any valves in the chlorinesolution line so as to isolate the ejector assembly.

c. Open the 1˝ PVC vacuum union MS-19 byunscrewing (counter clockwise) the union ringand move the vacuum piping out of the way.

Be careful not to lose the vacuum union o-ring.


d. Open or disconnect the 2˝ unions, flanges,fittings, etc., holding the ejector assemblyinto the pipeline, and remove the ejector.WHEN REMOVING AND/OR INSTALLINGTHE COMPLETE EJECTOR ASSEMBLY,BE CAREFUL NOT TO LOOSEN OROVERTIGHTEN THE NOZZLE AND THROATWHICH COULD CAUSE DAMAGE TOTHESE PARTS AND/OR WATER LEAKS.

e. Carefully clean or remove any foreign materialthat may have accumulated in the ejectornozzle or throat area, being careful not toscratch or mar the nozzle orifice.

NOTE: DO NOT USE SHARP TOOLS OR ALTER THE SIZEOF THE ORIFICE IN ANY WAY.

f. If chemical deposits have built up in the nozzleor throat area, immerse the part in muriaticacid. REMOVE ALL O-RINGS OR GASKETSFIRST.

IMPORTANT: READ ALL WARNING LABELS ON MURIATICACID CONTAINER AND FOLLOW ALL SAFETY INSTRUCTIONS.

g. Reassemble by reversing steps “a” through “e”.

If frequent ejector check valve failures causing flooding of thegas feed system components are a concern due to poor qualitywater, etc., Chlorinators Incorporated offers as an optionalaccessory “SECONDARY CHECK VALVE ASSEMBLIES.” (SeePhotos 12 and 13).

The SECONDARY CHECK VALVE ASSEMBLY is installed inseries with the primary check valve in the ejector. This nowmeans that both the primary and the secondary checkvalves must fail in order to flood the remainder of the systemcomponents.

For best protection, the primary check valve device should bechecked for failures as often as necessary and repaired assoon as a failure is detected. THE FREQUENCY OF CHECKINGTHE PRIMARY CHECK VALVE IS DETERMINED BY THESYSTEM, THE QUALITY OF THE CHEMICAL BEING USEDAND, THE QUALITY OF THE EJECTOR SOURCE WATER.

#1 The ejector is installed directly at the application point using the standard spray diffuser furnished with most REGAL Gas Feed Systems. An advantage with this installation is that “total” back pressure is equal to the application point pressure and the booster pump therefore need only be large enough to supply the hydraulic requirements of the nozzle.

A disadvantage with this installation is that the water main has to be shut down and de-pressurized in order to service the ejector assembly, booster pump, etc.

#2 In this installation, the end of the standard spray diffuser is cut-off to allow unimpeded flow through the ejector. A corrosion resistant valve such as a PVC ball valve is then screwed onto the cut-off end of the diffuser and a remote spray or open end diffuser is screwed into the other end of the ball valve. The ejector with ball valve and remote diffuser is then installed directly at the application point.

As long as the ball valve and diffuser are sized properly, this installation, like the #1 installation above, has the advantage of “total” back pressure being equal to the application point pressure plus an added advantage since the ejector, booster pump, etc. can now be serviced WITHOUT shutting down and/or de-pressurizing the water main.

#3 Often, the ejector is installed remote from the application point. Even though this is an acceptable (but not the preferred) installation, special consideration must be given to the following:

a. A chlorine solution line is a dangerous chlorine pressure line with a chlorine solution strength as high as 3500 parts per million. If this line breaks, the high concentration of chlorine will present a hazard to personnel and/or property.

b. The solution line and solution line fittings must be sized properly to assure that friction losses in this line DO NOT exceed 5' per 100' of equivalent pipe length.

c. A diaphragm protected pressure gauge should always be installed as close to the discharge side of the ejector as possible. This gauge provides a reading of "total" back pressure (application point pressure plus all additional pressures due to frictionlosses created by the solution line, fittings, elevation differences, etc.).

Ejector Installation with Ball Valve to Allow Positive Shut-off when Servicing of the Ejector is Required

Remote Mounted Ejector Installation for Gas Feed Rates up to 100 PPD.

NOTES:1. This installation is suitable for back pressures up to 150 psig and gas feed rates up to 100 PPD.2. If necessary, ejector can be installed at a remote location from the ball valve and diffuser.

NOTE:Threaded and hose interconnection sizes and ball valve size must be adequate to limit friction losses to a maximum of 5' per 100'of pipe or hose length.

14

DRAWING NO. 2Typical 100 PPD And Below Ejector Inlet And Outlet Connections

NOTE:1. When the REGAL Ejector is mounted at a location remote from the application point, the end of the standard diffuser (E-240)

MUST be cut off to allow unrestricted flow or, an E-248 1" long open end diffuser should be furnished with the system when ordered.

2. The chlorine solution line shown above is oversized to minimize additional back pressure due to friction losses. A rule of thumb is to keep friction losses to a maximum of 5' per 100' of equivalent pipe length. This calculation MUST take into consideration: elevation differences, number of elbows, valves, fittings, etc.A. Depending on the variables noted above, the water supply line to the ejector MAY need to be oversized as well.

3. To determine the hydraulic requirements needed to operate the REGAL Ejector, refer to Application Bulletin 1002 or 1009.

IMPORTANT NOTE: The following nozzle selection charts are forCHLORINATORS, SULPHONATORS and AMMONIATORS.When the ejectors are used on gases other than chlorine, besidematerial changes, a factor must be used to determine the equivalentchlorine capacity before using these charts.

Since the density of Sulfur Dioxide is essentially the same as chlorine,the nozzle sizing is the same and the charts can be used as printed.

For ammonia, multiply the capacity by 0.5 and size using theappropriate chlorinator chart.

HYDRAULIC CONSIDERATIONS

In order to achieve proper operation of the chlorinator, it is essentialthat you carefully identify and consider the various factors relatedto installation of the ejector. These hydraulic conditions (listedbelow) must be known in order to create sufficient vacuum tofeed the desired amount of chlorine gas.

1. BACKPRESSURE

a. Backpressure is simply the total water pressure measuredimmediately downstream of the ejector outlet. In Figure 1, ifa pressure gauge were to be installed between the ejectoroutlet and the water main, it would read the backpressure.

b. Beware of “ASSUMING” the backpressure to be the sameas the water system pressure. Pressures throughout awater system can vary greatly.

c. Always consider the maximum backpressure.

2. SUPPLY PRESSURE

a. Supply pressure is the water pressure measured at the inletof the ejector.

b. A pressure gauge should be permanently installed in theejector supply line, as close as possible to the ejector inlet.

c. The required ejector supply pressure can be obtainedfrom any source, as long as the minimum pressureand water flow are available (See Ejector NozzleRequirements charts on the following pages). A boosterpump must be added if necessary.

3. DIFFERENTIAL PRESSURE

a. This is the difference in pressures between the ejector supplypressure and the backpressure. This is often referred to asthe pressure “drop” across the ejector.

b. The differential pressure required to properly operate thechlorinator at a particular chlorine feed rate, will vary asthe backpressure increases or decreases. Generally, asbackpressure increases, the required differential pressurewill increase.

c. Water “booster” pumps are commonly used to create adifferential pressure by raising the system pressure andthen passing the higher pressure water through the ejectorand back into the system (See Fig. 1). However, a boosterpump is not always necessary to obtain the requireddifferential pressure.

4. FRICTION LOSS

a. Friction loss is a term used to describe RESISTANCE towater flowing through pipes, valves and fittings. In general,smaller pipe diameters, longer pipe length, and increasednumbers of valves and fittings, will create more friction loss.

b. In ejector installations, it is important to determine if anysignificant friction loss can occur:

EJECTOR SUPPLY - friction loss on the water supply sideof the ejector will result in lower water pressure available.

BACKPRESSURE - friction loss between the ejector outletand the point of chlorine solution injection, will create higherbackpressure.

c. Friction loss can be calculated from information found instandard books, such as Cameron’s Hydraulic Data, orfrom tables published by pipe and fitting suppliers.

HOW TO USE THE EJECTOR NOZZLEREQUIREMENTS CHART

The charts on the following pages represent minimum values(Ejector Supply Pressures and Water Flow Rates through theejector) necessary to operate a REGAL Series 200 GasChlorinator at each maximum metering tube (rotameter) capacity,against specific backpressures.

THE NOZZLE (or Venturi)

The nozzle in your REGAL ejector is chosen to give you thewidest range of serviceability in most standard applications at themaximum chlorine gas feed rate on the metering tube.Chlorinators Inc. has designed several different sizes of nozzles.Figure 2, below, shows the location of the stamped size designation:

STANDARD NOZZLE

The “Standard Nozzle” shown on each chart is the one whichwould be supplied with a REGAL Series 200 Gas Chlorinatorbased on the maximum capacity of the system. (EXAMPLE: achlorinator with a maximum capacity of 25 PPD (500 gr./hr.) willnormally be supplied with a size 5A nozzle).

*Standard Nozzle Supplied with Chlorinator for Indicated Maximum Feed Rate. NOTE: GPM is U.S. Gallons. Metric is liters per sec. (l/sec.)

REGAL EJECTOR NOZZLE REQUIREMENTS

USING THE CHARTSTo find out what hydraulic conditions you need to operate thechlorinator, follow these steps:

1. a. Determine the maximum required feed rate for thesystem to be treated.

b. Refer to the Maximum Chlorine Feed Rate Charts onthe following pages. Select the chart for the feed ratethat is next higher than your system’s required maximum.Ideally, your system’s requirement should be about50% to 75% of the chlorinator’s maximum feed rate.Do not select a chart for a feed rate that exactlymatches your system’s requirement. Use the nexthigher chart. With this approach, the metering ballshould be in the upper half of the metering tube formost adjustments that you might have to make.

IMPORTANT NOTE: You may not need to feed the maximumrate of gas flow on the metering tube, but you should still usethe values given for that maximum capacity.

2. Using the column headed “EJECTOR BACKPRESSURE”find the maximum backpressure for your system (seedefinition of “backpressure” on previous page) in English units of PSIG or Metric units of (kg/cm2).

3. Follow the backpressure line across to the first column underthe heading “STANDARD NOZZLE,” marked with an (*).

4. Read the required minimum “EJECTOR SUPPLY PRESSURE” in PSIG or (kg/cm2) and immediately to the right of EJECTOR SUPPLY PRESSURE, read the requiredminimum “WATER FLOW RATE” in U.S. GPM or (liters/sec).

5. The difference between the Ejector Supply Pressure andthe Backpressure is the required DIFFERENTIAL PRESSURE(see previous page).

Example: Using a water treatment system as in Fig. 1, with apressure in the water main at the ejector of 60 PSIG maximum(4.21 kg/cm2) and a desired chlorine feed rate of 18 PPD.

a. Use the 25 PPD chart.

b. Under “EJECTOR BACKPRESSURE” locate 60 PSI(4.21 kg/cm2) and read across to the “STANDARDNOZZLE No. 5A*” column.

c. The EJECTOR SUPPLY PRESSURE must be at least94 PSI (6.61 kg/cm2) and the nozzle will require atleast 10.8 U.S. GPM (0.68 l/sec.) WATER FLOW.

d. Therefore, the DIFFERENTIAL PRESSURE necessaryis 34 PSI (2.40 kg/cm2) or 94 (6.61) minus 60 (4.21).

e. In this example, a booster pump is used to take waterfrom the system and raise (boost) the pressure atleast 34 PSI (2.40 kg/cm2).

NOTE: However, if another, independent water source wereavailable that could provide the ejector with at least 94 PSI(6.61 kg/cm2) pressure at 10.8 U.S. GPM (0.68 l/sec.) thatwater source could be used to operate the ejector without abooster pump.

USING A NON-STANDARD NOZZLE

It may be necessary to use a nozzle which is not “standard” forthe capacity of the chlorinator. This is usually caused when:1. A REGAL Gas Chlorinator is replacing an older, existinggas chlorinator and available hydraulic conditions do notmatch the specifications for the “standard” REGAL nozzle.

2. Or, an existing booster pump is not capable of providingrequired water flow and/or pressure.

3. Or, the water supply and/or solution pipe may be toosmall compared to the flow rate for the standard nozzle. Adifferent nozzle may require a lesser flow for a givencapacity and therefore produce less friction.

In these cases, use the chart appropriate for the MaximumChlorine Feed Rate. Find the EJECTOR BACKPRESSURE,and look across the nozzle columns to find EJECTOR SUPPLYPRESSURE and WATER FLOW RATE which the system canmeet. Use the nozzle shown at the top of that column.

NOTE: If it does not appear that your application can meet therequirements shown, contact Chlorinators Incorporated.
