These pages contain guidelines for system design and generalsafety. It is essential to review all Operation and MaintenanceInstructions before proceeding with installation of this equipment.

1. General Description

The MEMDOS E/DX is an intelligent motor driven metering pumpthat combines digital technology and state of the artmicroprocessors with high quality mechanics. The new MEMDOSseries is very flexible and versatile in the area of external control.Its functionality incorporates the latest requirements in meteringtechnology.

Two chassis sizes of the MEMDOS are available, each with orwithout microprocessor control. The smaller chassis can be usedfor capacities from 0 - 42 gph and the larger chassis for capacitiesfrom 0 - 92 gph. Pressure ranges are available up to 150 psi,depending on capacity.

2. System Design Guidelines

Before installing the MEMDOS E/DX into a new or existing system,Lutz-JESCO America Corporation recommends careful review of yoursystem’s design and layout. It is essential that all local rules,codes and regulations are followed in the design and installation of

chemical feed equipment. It is also important that the systemmeets the technical demands required, such as flow rates andpressures. Many factors must be taken into consideration, includingprocess fluid specifications, material compatibilities, chemicalhandling, electrical wiring, line losses and many more.

Ambient temperatures exceeding 104ÞF are not permitted on DXmodels. Radiant heat of apparatus and heat exchangers must bekept in acceptable limits allowing the pump to sufficiently dissipateits own heat. Exposure to direct sunlight must be avoided. If thepump is installed outside, provide an enclosure to protect it againstthe weather.

With metering pump systems, particular attention must be paid tothe piping system. Refer to Jesco America Corporation’s SystemDesign Guide for more detailed information.

Both the system designer and the operator are responsible

for ensuring that the entire plant is constructed to prevent

unreasonable damage to plant equipment or building

resulting from leakage or technical failure.

It is especially important that chemical plants be designed toensure the safety of maintenance people and operators. Werecommend installing relief valves, splashguards, containmenttanks, and leakage probes with alarm relays to aid this effort.

3. Safety Precautions

The diaphragm metering pump is designed to pump various liquidsinto pressurized systems. By nature, the application of these pumpsmay present circumstances under which personal hazards can exist.All personnel who may have occasion to install, operate, or maintainthese pumps should be provided with the opportunity to read thisinstruction manual and be familiar with its contents. Awareness ofpotential hazards can prevent accidents and injury.

Danger from Liquids Handled

All systems containing liquid and/or air under pressure present thepotential for unexpected discharge of liquid in a violent manner. Inoperation and servicing of the pump, all parts of the pump and attachedpiping which contain liquid should be treated cautiously, until it isknown with certainty that they have been depressurized and drained.

Danger from Electrical Hazard

Since these pumps are electric motor driven and may includeelectric components, the hazard of electrical shock can exist.Installation and wiring of electrical components should be inaccordance with the applicable codes.

Operational Hazards

To avoid personal injury, please adhere to the following guidelines:

1. Do not operate the pump if electrical component enclosures arenot in place.

2. When venting pump head or piping during startup, liquid may bedischarged under pressure. The use of a pressure reliefmechanism back to the supply tank is highly recommended.Suitable caution should be taken to avoid contact with the liquidand to avoid spillage or spraying of liquid.

3. Clean up any leaked or spilled liquid immediately.

Safety1. Before operating pump and accessories or attempting to service,

become familiar with the contents of this instruction manual.2. Observe all precautions established by plant safety procedures.3. Observe all chemical handling instructions provided by the

chemical supplier and/or plant regulations.4. Do not operate pump with closed valves in suction and/or

discharge lines.5. Do not paint over or remove nameplates, labels, or tags.6. In disassembly of pump, precautions should be taken for the

possibility that a diaphragm rupture may have allowed pumpedliquid to contaminate the housing.

7. If motor replacement is required, be certain that all specifica-tions are the same as the original motor.

8. If a pump is to be used for other than original service, firstascertain that pump is suitable for new conditions (pressure andcompatibility with liquid to be pumped).

9. Establishment of and adherence to a regular maintenanceprogram can prevent problems by early detection of unusualconditions (e.g. unusual noise, overheating, and wetnessindicating leakage).

4. Installation

The accuracy and reliability of a metering pump system depend onproper installation of each component. All considerations of soundhydraulic practice, including the elimination of air and foreignmatter, accurate and reliable seating of valves, proper size andlength of piping, liquid vapor pressure, viscosity, and temperaturemay mean the difference between a successful or unsuccessfulinstallation. The application of basic hydraulic principles duringplanning, installation and operation is essential. Good suctionconditions will prevent a common cause of premature diaphragmfailures. Each installation should be designed and built payingcareful attention to all instructions regarding handling of corrosive,toxic or hazardous chemicals. It is of utmost importance that allsafety procedures established by the owners and manufacturers befollowed during installation, operation and maintenance phases.

Location

The preferred location of a metering pump system is indoors.Although systems can be installed outdoors, manufacturer’stemperature ratings and recommendations must be followed. Gearlubricants and system fluids are subject to viscosity increase whentemperatures fall. Motors and gear boxes are subject to overheatingwhen installed in direct sunlight or an area with high ambienttemperatures. If a system must be installed outdoors, it should besheltered from the elements with heating or cooling systemsprovided as needed. Proper installations indoors or out should allowsufficient room for operators and maintenance personnel to accesseach component for adjustments and servicing.

General Installation1. Install metering pump (1) with suction (2) and discharge (3)

valves vertical and bolt down the base.2. The piping must not exert any force on the suction and discharge

valves.3. The leakage tube from the separation chamber must slope down

to the supply tank (14).The drain should never pass directly through the tank lid back tothe medium as this could allow gasses to penetrate the pumpdrive. The drain must be directed to a vented collectioncontainer or to a collection funnel (5) with an appropriate gapbetween the pump and the return line. Leakage can then drainvia the funnel through the tank lid. Any leakage at the funnelwill therefore be apparent.

4. If the discharge line is 30 ft. or longer, a Pulsation Dampener (7)is recommended. A Pulsation Dampener may also be necessarywith higher viscosities.

5. The suction line (8) should be fitted with a suction filter (and afoot valve (9) for suction lift applications).

6. Safety switches should be installed for motors, in accordancewith the relevant codes.

7. Suction line should not be smaller than pump suction connec-tion. Some pump applications may even require larger suctionlines.

Electric Installation1. Check motor nameplate and compare power supply requirements

with characteristics of available power.2. Check motor rotation, which must be counter-clockwise when

operator is viewing rotation of fan.3. Electrical installation including motor control and overload

protection must be in accordance with applicable codes andlocal ordinances.

Installation Example

Installation Components 1. Metering Pump 9. Foot Valve 2. Suction Valve 10. Vent Valve 3. Discharge Valve 11. Relief Valve 4. Mixer 12. Back Pressure Valve 5. Collection Funnel 13. Injection Valve 6. Tank Drain 14. Supply Tank 7. Pulsation Dampener 15. Power Supply 8. Suction Line 16. Tank Vent

Drain Pipe

The drain pipe must be routed with a downward slope to a supplytank free of gases or to a collection funnel, which should be placedno closer than 1 inch from the leakage tube. By no means must thedrain pipe be returned directly to the chemical through the tankcover, because otherwise effervescent media might enter the pumpgear. Leakage can be returned via the funnel through the tank cover.This also enables you to see possible leakage at the funnel.

Electrical Connection of Pump� The electrical connection of the pump must be made according

to the local rules and may only be carried out by technicalpersonnel.

� Cable type and cable cross section of the supply lines must beselected according to the motor data.

� The cable passages to the motor terminal box must be madeprofessionally. We recommend gland screw connections withtraction relief.

� The required protection class must be ensured by professionalinstallation of the electrical connections.

5. Operation and Start Up1. Remove oil fill cap located above stroke adjustment knob.

Using oil (P/N 261488) provided, fill the pump with oil throughvent opening until oil level is between markings on oil dip stick.Replace oil fill cap.

2. Open both the suction shutoff valve and system vent valve onthe discharge side to expose the system to atmosphericpressure. For flooded suction applications where pump andpiping will fill by gravity or for dangerous mediums, proceed toStep 12. For applications involving long suction lines or suctionlift, continue with Step 3. ATTENTION! If using a dangerousmedium, disregard Steps 3-11.

3. On the discharge side, unscrew the union nut of the dischargeline and the valve body from the liquid end.

4. Fill the liquid end from the top with the chemical medium orwater (if compatible). Place a collection pan under the pumphead to catch any spilled chemical.

5. Refit the valve body with the gasket to the liquid end.6. Turn on the pump motor. (Check direction of rotation according to

arrow.)7. Adjust the pump stroke length to 100%. Refer to Capacity

Control Adjustment instructions on this page.8. Note that the liquid, together with obvious air bubbles, will

escape through the thread of the valve body and the liquid end atthe top.

9. As pump runs, the suction line will fill with liquid medium andair will be released. When air bubbles cease at loose fittings,tighten discharge valve body onto the liquid end.

10. Turn the pump off.11. Refit the discharge union nut and the discharge line, making

sure that the gasket (washer) is replaced.12. Turn pump on and check for flow from the system vent valve

(with properly installed return lines).13. When flow is verified by system vent valve, close the vent

valve.14. The pump can then be adjusted to the output required. The liquid

end and pump body should be cleaned off and dried to preventany attack of the medium where the necessary spillage hasoccurred due to the above procedure.

15. If the pump fails to self-prime, detach the discharge valve andfill the pump head with liquid. Use water if possible to avoidhandling chemicals. Replace the valve and tighten. Turn thepump back on. Once the delivery has been achieved, adjust theoutput setting as required.

16. A minimum back pressure of 15 psig is required in order toprovide proper check valve seating as required.

17. After first 500 hours of operation, see Maintenance Information.

Note: Jesco America Corporation is not responsible for

damages due to excessive or low flow rates resulting from

faulty pump settings or incorrect and insufficient installation

of peripheral fittings.

Capacity Control Adjustment - ManualPump capacity control has been tested at the factory. However,verification of specified discharge pressure is important as it affectsdelivery rate. To calibrate pump to actual application, follow theprocedure below.

1. Make sure that the pump is delivering the process fluid atsystem pressure.

2. Loosen control knob shaft lockscrew. Turn capacity control to 10graduation on capacity control dial and record maximum pumpoutput.

3. Determine and record pump output at a number of other capacitycontrol settings.

4. Plot graph of pump output versus capacity control settings.Effects of discharge pressures specific to the application maycause zero output occurring at some capacity control settingabove zero.

Capacity Control Adjustment - ElectricSee electronic capacity adjustment (ATE) instructions whenapplicable.

General

Jesco America Corporation diaphragm metering pumps requireminimal maintenance when properly installed. The standard versionof the pump integrates a separating chamber function. For specialapplications, a second separating chamber can be added to ensurebetter protection of the pump gear unit. In both versions, anyleakage is drained off through a drainage pipe. For electricalevaluation, an additional leakage probe can be installed.

If a diaphragm should fail due to wear, it is possible that the mediummight come in contact with the environment. This creates apotentially dangerous situation.

To avoid this, a hermetically sealed double-diaphragm system wasdeveloped. It can be integrated into all MEMDOS series pumps andis adapted to the relevant capacities and operating pressures.

Construction and FunctionThe double diaphragm system is fixed between the metering headand the diaphragm flange of the pump. The housing (1) constructionis plastic. It is equipped with a filling socket (4) and a drain plug(5). The second diaphragm (2) separates the medium from theglycerin-filled working chamber (3). If the chamber between the twodiaphragms does not contain air, the separating diaphragm followsthe movement of the main or operating diaphragm. A failure of theseparating diaphragm (2) does not affect the pump function. It willonly result in the medium mixing with the glycerin in the chamber.If the operating diaphragm fails due to wear, only the glycerin willescape from the drainage pipe of the diaphragm flange. The mediumis hermetically sealed by the separating chamber.

Leakage Alarm

On the basis of conductivity measurement, the double-diaphragmsystem can be equipped with a leakage probe. If the glycerin ismixed with the medium, its conductivity changes. This change isdetected by a two-rod electrode and can be evaluated electrically. Alevel relay is required for this purpose. Contact the factory forfurther information.

Note: Due to the compressibility of the separating dia-

phragm, the metering capacity may be 10% lower (depend-

ing on the backpressure).
