Model 3700 11th Edition (ISO 13709)API Revision Summary

724.1A100July 14, 2011

(Sup. 10/1/04)

The following is a listing of the major changes resulting from API−610 and API−682 − latest edition − and changes madeto the 3700 to comply:It must first be noted that, although all references to API−610 in the latest issue of prism/epb show “11th” Edition, thebelow listed changes are actually addressed in “9th” Edition. One of the purposes for updating API−610 was to bring it intoaccordance with ISO standards – in particular – ISO Std 13709. However, at the time of completion of 9th Edition, ISO13709 1st Edition was not yet fully completed. It was decided by API not to delay issuing 9th Edition due to this. Within thetime frame of 9th Edition issue and review of this standard for impact to our product offerings, ISO 13709 1st Edition wasfinalized. API has voted to issue 11th Edition to resolve the “editorial” differences between API−610 9th Edition and ISOStd 13709 1st edition thus making API−610 fully compliant with ISO 13709. Although API is proceeding on this basis,formal issue of 11th Edition has not yet taken place. It is expected to be issued within the next two months. Rather thanwait for formal issuance of 11th Edition, we have elected to proceed with revisions to Prism/EPB with reference to 11th

Edition since it is being issued for editorial revisions only and will not impact any of the changes between 8th and 9th

Edition noted below. This will preclude the need to re−issue prism once 11th Edition is formally issued.There are numerous “minor wording/editorial” changes and clarifications in 9th/10th Edition. The following reflects only the“major” changes between API−610, 8th Edition and API−610, 9th/10th Edition:General:

1. "ISOization" of API−610 standard.

Basic Design – General:2. Para. 5.1.6 (8

th Ed. Para. 2.1.4) – 105% TDH increase requirement is not intended to accommodate future

expandability, but instead is to prevent change in selection caused by refinements in hydraulics after pump hasbeen purchased. Any “future” head requirements must be noted separately by the purchaser. (Does not impactcurrent 3700 “design”).

3. Para. 5.1.16 (8th

Ed. Para. 2.1.16) – Addresses additional requirement for supplying not only “sound pressure”levels, but also providing “sound power” levels, when specified. (Does not impact current 3700 “design”).

4. Para. 5.3.1/5.3.2 (not in 8th

Edition) – adds criteria to establish maximum discharge pressure for engineeredpumps. (Does not impact current 3700 “design”).

Basic Design – Pressure casings:5. Section 5.3 (8

th Ed. Section 2.2) – added criteria for basic design requirements of pressure casings and

removed “specific” references to ASME, thus providing more generic format. (Does not impact current 3700“design”).

Basic Design – Rotors:6. Para. 5.6.14 (Not in 8

th Edition) – added criteria for fillet radii for keyways. (3700 keyway arrangement

complies).7. Para 6.6.1 (11th Ed.) allows semi−open and open impeller designs in addition to enclosed impeller designs

Basic Design – Wear Rings:8. Para. 5.7.1 (8

th Ed. Para. 2.6.1) – allows for integral wear surfaces. (Does not impact current 3700 “design”.

3700 arrangement will continue with “replaceable” wear rings).9. Para. 5.7.3 (8

th Ed. Para. 2.6.3) – allows mounting of wearing rings by “tack welding” without any longer

requiring customer approval of this method. (Does not impact current 3700 “design”. 3700 arrangement willcontinue with “set−screwed” wearing rings as standard. However, should the need arise to mount by tackwelding, this method will be employed without obtaining customer authorization unless customer specificationoverrides this and still mandates their approval.)

Mechanical Shaft Seals:10. Para. 5.8.1/5.8.2 (8

th Ed. Para. 2.7.1 thru 2.7.3) – all mechanical seal requirements are now per API−682.

Major changes to API−682 are noted below. (Does not impact current 3700 “design”. Catalogued 3700 sealselections conform to Category 2 seals as defined by API−682).

11.Para. 5.8.9 (8th Ed. Para. 2.7.3.17) – clarifies that jacket seal chambers are for “heating purposes” only. (Doesnot impact current 3700 “design”).

724.1A100July 14, 2011(Sup. 10/1/04)

The following is a listing of the major changes between API−682, 1st Edition and latest API−682, 2nd

Edition:

There are numerous “minor wording/editorial” changes and clarifications between 1st and 2nd Edition. Thefollowing reflects only the “major” changes:

General:1. “ISO−ization” of API−682 standard.

Seal Categories:2. Now defines seals in three basic categories:

• Category 1: − “…intended for use in non−ISO 13709 seal chambers, preferably meeting thedimensional requirements of ANSI/ASME B73.1, ANSI/ASME B73.2 and ISO 3069 Type C sealchamber dimensions”. Category 1 seals limited to seal chamber temperatures from −40 deg. C (−40deg. F) to 260 deg. C (500 deg. F) and maximum pressure of 22 bara (315 psia).

• Category 2: − “… intended for use in seal chambers meeting the chamber envelope dimensionalrequirements of ISO 13709.” Category 2 seals limited to seal chamber temperatures from −40 deg. C(−40 deg. F) to 400 deg. C (750 deg. F) and maximum pressure of 42 bara (615 psia). Prism/EPBcatalogued seal arrangements comply with specified Category 2 seal arrangements.

• Category 3 – “… provides the most rigorously tested and documented seal design. It is required thatthe entire seal cartridge is qualification tested as an assembly in the required fluid in accordancewith Clause 10 and are provided with all the data requirements specified in Clause 11. Category 3arrangements are limited to same temperature/pressure conditions specified for Category 2 seals.Category 3 seals require completion of API−682 seal data sheet and quotation direct by seal vendor.No Category 3 seals are included in Prism/EPB.

Seal Types:3. Now defines seal "types" as follows:

• Type A – Pusher seal, flexible element rotates, O−ring sealed.• Type B – Bellows seal, flexible element rotates, O−ring sealed.• Type C – Bellows seal, flexible element stationary, Flexible graphite sealed.

Seal Arrangements:4. Now defines seal "arrangements" as follows:

• Arrangement 1 – one seal per cavity.• Arrangement 2 – Two seals per cavity, unpressurized. Available in face−to−back (tandem),

back−to−back, face−to−face.• Arrangement 3 – Two seals per cavity, pressurized. Available in face−to−back (tandem),

back−to−back, face−to−face.

Seal Codes:5. Now defines seal "codes" as follows"

• CW – contacting wet• NC – non−contacting (wet or dry running)• CS – containment seal• FB – front−to−back (tandem)• BB – back−to−back (dual)• FF – front−to−front (dual)• FX – fixed bushing• FL – floating bushing


724.1A100July 14, 2011(Sup. 10/1/04)

Gas Seals and gas seal systems:6. Gas seals are now included. However, no gas seal arrangements are included in Prism/EPB. Quotations for

such must be obtained direct from seal vendor.7. Gas seal barrier systems are now included:• Plan 71 – connections only for future buffer gas (similar to Plan 61).• Plan 72 – unpressurized (similar to Plan 52).• Plan 73 – pressurized (similar to Plan 53)• Plans 74,75 and 76 – for various applications.

Above gas seal barrier fluid system options are not currently included in Prism/EPB. Quotations for such, when specified,must be obtained direct from seal vendor. Contact Factory for pricing for “interconnecting” piping between gas panel andseal.

Seal flush piping/barrier fluid piping systems:8. Heat exchanger size requirements (Plans 21, 22, 23, 32 and 41) are now based on shaft diameter size:• Shaft diameter 60mm (2.5 in.) or less = ½”, .065 wall heat exchanger tubing.• Shaft diameter greater than 60mm (2.5 in.) = ¾”, .095 wall heat exchanger tubing.9. Seal reservoir size requirements (Plans 52 and 53A, B, C) are now based on shaft diameter size:• Shaft diameter 60mm (2.5 in.) or less = 12 l (3 gallon), Sched. 40 reservoir.• Shaft diameter greater than 60mm (2.5 in.) = 20 l (5 gallon), Sched. 40 reservoir.

Prism/EPB piping plans reflect above heat exchanger/seal reservoir sizing criteria.


Model 3700 11th Edition (ISO 13709)Product Description

724.1A105July 14, 2011(Sup. 06/01/09)

The Model 3700 11th Edition pump is an overhung, horizontal centerline mounted process pump designed to meet thedemanding requirements of API 610 11th Edition (ISO 13709), “Centrifugal Pumps for Petroleum, Petrochemical andNatural Gas Industries.” The Model 3700 is classified as Type OH2. The Model 3700 is capable of Pressures to 5.8 Mpa(845 psi) and temperatures to 425°C (800°F).

Casing

Casings are machined from a one piece casting and are designed for severe service. The casing and nozzles aredesigned to withstand two time API 610 nozzle loads without causing distortion that would impair operation. Casingsupport brackets are extra thickness to resist piping loads and are arranged for centerline mounting. Casing hold downbolts are spaced to provide maximum rigidity and minimize deflection. Accurate alignment between the casing and theseal chamber cover is achieved by a metal to metal rabbeted fit. Casing and seal chamber cover are sealed by a spiralwound stainless steel gasket. Dual volutes are furnished on 3 inch and larger discharge sizes***. Standard flanges areANSI Class 300 RF.

Seal Chamber

The seal chamber dimensions fully conform with API Standard 682 (ISO 21049) dimensions. All types of cartridgemechanical seals conforming to this standard can be accommodated.

Impeller*

Enclosed one piece casting is externally fully machined. All impellers are dynamically balanced to ISO G1.0 (4W/N)

requirements to minimize vibration. Front and rear wear rings with balance holes provide axial hydraulic balance.Multiple impellers are available for each size to meet specific hydraulic requirements. The impeller is keyed to the shaftand held in place with an impeller nut that tightens against rotation. A set screw in the impeller nut provides a positivemechanical lock to further prevent loosening.

Wear Rings*

All pumps are fitted with renewable impeller, casing and impeller wear rings. Case cover wearing rings are secured by tagwelding and impeller rings by set screws. Standard clearances are as specified by API 610 (ISO 13709).

Shaft

The rigid shaft design limits shaft deflection to less than API 610 (ISO 13709) allowable values. Shafts are fullymachined and ground to assure dimensional accuracy and concentricity. Keyways for the impeller and coupling are sizedto transmit the full power requirements and are furnished with adequately sized fillets to reduce stress concentrations. Shaft sizes in the seal chamber area conform to API 682 (ISO 21049) dimensions.

Bearing Frame and End Cover

Carbon steel bearing material is standard. Integrally cast cooling fins increase heat transfer and reduce oil temperature. Additional cooling can be provided by the addition of a heat flinger, heat flinger/thrust fan combination or by a watercooling tube immersed in the oil. Non sparking metal labyrinth deflectors exclude dirt and moisture.

Bearings **

The thrust bearing is a paired, single row, 40 degree angular contact arrangement with light preload. The radial bearingis a single row, deep groove type. Thrust bearings are secured to the shaft with a locknut and tab type lockwasher. Thethrust bearing is held in place in the frame by the bearing end cover. The radial bearing is pressed on the shaft and is freeto move axially in the bearing frame.

Baseplate

Rugged fabricated steel drip pan type baseplate is designed to support the pump and driver and maintain alignmentwhen subject to API Table 4 piping loads. External corners of the baseplate in contact with grout have 50 mm (2 inch)radius corners. Grout contact surfaces are sandblasted and coated with inorganic zinc silicate. Vertical leveling screwsare provided on the outside perimeter of the base. A minimum of four lifting lugs are provided. All baseplate joints, topand bottom, are completely seal welded.*3700 LF Pumps use a semi−open impeller with balance holes and no wear rings. In addition, they use a cap screw instead of an impeller nut with set

screw

**3700LF 2x4−17.5 Pumps use a cylindrical roller radial bearing

***3700 LF Pumps all have single volutes

Model 3700 11th Edition (ISO 13709)Selection Guidelines

724.1A205July 14, 2011(Sup. 09/15/07)

General The Model 3700 is a rugged, heavy duty API 610 (ISO 13709) process pump designed to handle a wide range ofpumpages and operating conditions. It is designed to fully comply in all respects with the requirements of API 610 11th

Edition (ISO 13709). The Model 3700 is offered in two power frame arrangements. The “A” Series power frame fullyconforms to all the requirements of API 610 11th Edition (ISO 13709) when applied within its service limits. The “X”Series power frames conform to API 610 (ISO 13709) plus the additional requirements imposed by various pump usersand engineering contractors, primarily those located in the U.S.A. The X Series is also used meet requirements on moredemanding and/or severe services.

Following are the selection guidelines for the Model 3700.

A. Hydraulic Requirements General SelectionAll performance curves are based on standard API 610 (ISO 13709) clearances. Wear ring clearanceswill be increased 125 µm (0.005 in.) when the pumpage temperature exceeds 250 C (500 F) or whengalling materials are furnished. Pump efficiency must be decreased by one (1) percentage point across thecurve. As a minimum, the rating must be within the Allowable Operating Region shown on theperformance curve and should preferably be within the Preferred Operating Region (70 to 120% of BEP).

NPSHNPSHR values shown on the performance curves are based on a 3 percent drop in head as tested on water.NPSHR must be less than NPSHA throughout the entire required operating range, including any run outpoints.

Minimum FlowSelect pumps so that all operating points are greater than the minimum continuous stable flow. For lightvolatile hydrocarbon liquids, it may be necessary to determine the minimum thermal flow. Methods fordetermining both the minimum continuous stable flow and the minimum continuous thermal flow aredescribed on page 724.1A410.

B. Power Frame Requirements

A Series and X Series power frames are available. The X Series power frames may be required due tocustomer specification requirements or because the hydraulic requirements exceed the A Series powerframe’s capabilities. The use of the X Series power frame is required whenever the operation conditionsdo not permit the A Series frame to operate within API 610 (ISO 13709) requirements. Determination ofwhich arrangement to use can be separated into two categories:purchaser requirements and mechanicalrequirements.

Purchaser RequirementsSome pump users and engineering contractors, mainly those located in the U.S.A., but also those globalcompanies heavily influenced by the US companies, have specifications that modify API 610. Thesepurchasers may impose additional requirements or evaluate pump design using criteria more restrictivethan API 610. Additional requirements may be tighter limits on shaft deflection, or a minimum shaft sizeunder the seal. Evaluation criteria are used to determine pump acceptability and one component is shaftdiameter. L3/D4 is the most common example. L is the shaft overhang (distance from the radial bearingto the impeller centerline) and D is the shaft diameter under the seal. In this evaluation, L3/D4 is used torepresent shaft deflection potential. Pumps with low values are preferred. The pump with the lowestL3/D4 is considered the base and a price penalty is assessed on pumps with high values. Depending on thedifferences in the L3/D4 values and the amount of the penalty applied, it is possible for the price penalty tobe greater than the proposed price of the pump.


724.1A205July 14, 2011(Sup. 09/15/07)

The pump evaluation factors are generally not part of the inquiry documents. It is essential to know inadvancehow the purchaser will evaluate the pumps.The A Series frames have higher L3/D4 values than the X Series frames. If the purchaser will evaluatethe shaft diameter as part of his pump evaluation procedure, the X Series power frames must be offered. Al−though there is a price adder for the X Series, it will have a lower evaluation cost than a pump with the ASeries frame plus the evaluation penalty.

Mechanical RequirementsThe A Series power frames have temperature, suction pressure, shaft power and frame load (“M” Factor)limits as stated below. When these limits are exceeded, the X Series power frame must be used:

The pumpage temperature exceeds 426° C (800° F).• Suction pressure exceeds 35 bar (500 psi).• Power limits of the A Series frame is exceeded. This applies only to the LA frame and LX framewhen use on XLX sizes.

· The A Series frame load factor (M factor) is exceeded for the actual pump size and operatingconditions. The following chart lists sizes and applicable speeds where this limitation applies (i.e., “actual”frame load factor exceeds the “allowable” frame load factor). Where no values are indicated under the speedcolumn in the following chart, the actual pump load factor is less than the allowable frame load factor and theA Series bearing frames may be used for all cataloged operating speeds (unless already restricted per one ofthe above temperature, pressure, shaft power limitations).

The listed frame load factor limitations are based on fluids with specific gravities of 1.0. For pump sizeslisted in the chart where a restriction is noted, you may be able to use the A Series frames by taking intoaccount the actual specific gravity of the pumped fluid. The acceptability of the A Series frame can bedetermined as follows:

If: (Actual ‘M’Factor)x(Specific Gravity) < (Allowable ‘M’ Factor), Then: “A” series frame usable

If: (Actual ‘M’Factor)x(Specific Gravity) > (Allowable ‘M’ Factor), Then: “X” series frame only

C. Pressure LimitsPage 724.1A305 shows pressure temperature limits for the Model 3700. The maximum discharge pressureat operating temperature must be within the limits of the pressure−temperature chart for the material andflange rating being quoted.

[Max Discharge Pressure] = [Max Suction Pressure] +1.1x[pump pressure at shutoff, max driver speed]

Maximum driver speed for steam turbines is the overspeed trip setting. Should the customer future operatingconditions change, these conditions must also be within the pressure− temperature limits of the pump. Class300 RF flanges are standard. Other flange facings are available as options.


724.1A205July 14, 2011(Sup. 09/15/07)

D. MaterialsStandard materials of construction correspond with API material classes S−4, S−5, S−6, S−8, C−6, and A−8. The following commonly specified material classes which are standard should be addressed as follows:

S−1 (carbon steel case with cast iron impeller and wear parts)Quote S−4 construction (carbon steel case and impeller with cast iron wear parts). This is the minimumconstruction. The carbon steel impeller is a material upgrade over cast iron.

S−8 and A−8 use Nitronic 60 impeller wear rings and 316L casing and cover rings as standard. This materialcombination is inherently non−galling. Refer to 724.1A435 for a detailed description of the materials used ineach material class.

E. Shaft SealingShaft sealing is by cartridge mechanical seals only. All mechanical seals require an appropriate seal flushplan. Mechanical seals and sell flush plan recommendations on page 724.1A315 are general guidelines.

Seals included on pages 724.1B4 conform with API 682 (ISO 21049), Category 2. Seals which mustconform to API 682 (ISO 21049), Category 3 must have the API 682 (ISO 21049) data sheet submitted to theseal vendor who will supply an individual quotation for the service.

F. TestingAll casings receive a non−witness hydrostatic test as standard. No performance testing is included in the ba−sic pump price.

For liquids with a specific gravity of less than 0.7, a surfactant is used for the hydrostatic test, see price bookfor adder.


Model 3700 11th Edition (ISO 13709)API−610 Compliance

724.1A230July 14, 2011(Sup. 3/15/06)

The Model 3700 is designed to fully conform to API 610 11th Edition (ISO 13709). However, variousparagraphs within API 610, as well as customer specifications, impose requirements on how the pump oraccessories are to be selected and/or sized. Depending on the operating conditions, other paragraphs mayrequire special features which necessitate extra pricing. API610 also contains many “bulleted” (·)paragraphs. These bulleted paragraphs indicate that a decision is required or further information is to besupplied by the Purchaser.

When quoting pumps to API 610 and/or customer specifications, care must be taken so that all necessaryclarification statements and extra pricing, as applicable to specific selections being offered, are included inthe proposal. Contact Factory for any required assistance/guidance.

Model 3700 11th Edition (ISO 13709)Bearing Life

724.1A310July 14, 2011(Sup. 12/01/04)

All Model 3700 11th Edition (ISO 13709) pumps are supplied standard with impeller balance holes and frontand rear impeller and casing wear rings. The balance holes and wear rings reduce the pressure behind theimpeller. This lower pressure reduces axial hydraulic thrust and seal chamber pressure. At suction pressuresup to 35 bar (500 psig), the impellers with balance holes provide an L10 (in accordance with ISO 281) thrustbearing life of greater than 25,000 hours as required by API 610 (ISO 13709).

At higher suction pressures, however, bearing life may be reduced below the minimum API life of 25,000hours. In these situations it may be possible to plug the balance holes to restore axial hydraulic balance. Notethat the suction pressure limit for the A Series power frame is 35 bar (500 psi). When higher pressures areencountered, the X−Series frame must be supplied.

Contact the Factory for applications with suction pressures greater than 35 bar (500 psig) or whenevercustomer requirements specify bearing life greater than 25,000 hours.


Model 3700 11th Edition (ISO 13709)Mechanical Seal Selection Guidelines

724.1A315July 14, 2011(Sup. 09/15/07)

The following seal selection guide determines the seals to be used on the basis of the type ofliquid, the liquid properties, and the operating conditions. Each liquid and operating conditionrange is assigned a seal index number and a recommended seal flush plan. The seal indexnumber is listed on the price pages for the specific seal manufacturer for the appropriate sealtype.

The following general guidelines apply.• These are general recommendations only and are based on clean liquids without the

presence of solids or corrosives such as acids, caustics, ammonia, hydrogen sulfide,carbon dioxide, etc., and maximum pump operating speeds of 3600 RPM. For higherspeeds and for liquids outside the scope of these selection guidelines, a sealmanufacturer's recommendation must be obtained.

• Single seals on hydrocarbon services represent the minimum seal selection. Forliquids that are defined as hazardous or where the emission rate for hydrocarbons isregulated, dual seal configurations (unpressurized or pressurized) may be required.Dual seal selections with flush plan requirements are listed for each of thehydrocarbon services selection guidelines.

• If the customer's data sheet specifies a seal that is different from the followingrecommendations, the data sheet specified seal must be quoted. Seals selected fromthese guidelines may be offered as an alternate provided it is a technically acceptableoffering and it is clearly stated that it is an alternate. If the alternate seal type isacceptable, the customer must change the data sheet prior to order placement.

• It is the responsibility of the purchaser and the seal vendor to ensure the selected sealsand seal auxiliaries are suitable for the intended service. This is particularly true onhydrocarbon services where operating experience and knowledge of the actual fluidproperties affect the seal selection.

• If full API−610 9th/10th edition compliance is required API−682 (ISO 21049)Category 2or 3Mechanical Seals must be used. (Customer must specify applicable Seal Category).

Model 3700 11th Edition (ISO 13709)Minimum Motor Sizing

724.1A325December 1, 2004(Sup. 2/14/00)

High suction pressure applications cause very high loading of mechanical seal faces. Because these facesmust “break free,” the torque necessary to start a pump with high suction pressure can be greater than thatrequired at the rating point.

Motors sized for the rating point of pumps with relatively low flow and/or head may not have sufficienttorque to be able to start units on high suction pressure applications. This will primarily occur with SA or SXpumps, but may also be encountered on larger MA/MX or LA/LX sizes operating below 1800 rpm. In orderto assure that pumps falling within this criteria have sufficient starting torque, motors must be checked forcorrect sizing according to the graphs found on the following page.
