Warnings

1. Read the instructions before installing the pump and starting it up. Always follow the guidelines for assem-

bly in order to achieve optimum operational reliability.

2. Always check that the specifications of the motor and the motor control unit are correct, particularly in oper-

ating environments where there may be a risk of explosion.

3. Pumps should only be installed, disassembled, repaired and assembled by personnel trained in servicing pumps.

4. Always ensure that all electrical installation is carried out by qualified staff.

5. Never hose down or clean the electric motor directly with water or cleaning fluid. If the motor will be used in a washdown environment a washdown designed motor must be used.

6. Never dismantle the pump before the motor has been disconnected from the power supply. Remove the fuses and disconnect the cable from the motor terminal box.

7. Never dismantle the pump until the isolating valves on the suction and discharge side have been closed

and the immediate pipe system has been drained. If the pump is used for hot and/or hazardous fluids, spe-

cial precautions must be taken. In such cases follow the local regulations for personal safety when working with these products.

8. Always ensure that all pipe connections have been fitted and tightened properly before the pump is started. If the pump is used for hot and/or hazardous liquids, take special care: follow the local regulations for personal safety when working with these products.

9. Always wear personal protective equipment according to the requirements established by OSHA, NFPA, NEC (See page 9).

10. Always remove all assembly and auxiliary tools from the pump before starting it up.

11. Make sure product lines and power cables are laid in suitable guides/trays.

12. Always ensure that no debris of any kind is present in the pump.

13. Always ensure that the pump and the motor shafts are properly aligned.

14. Always ensure that the suction and discharge valves isolating the pump are fully open before starting the pump.

15. Never close or obstruct the outlet of the pump as the pressure in the system will increase above the speci-

fied maximum pressure of the pump and cause damage to the pump.

16. There are rotating parts in the pump. Never put hands or fingers into a pump while it is in operation.

17. The pump components and piping may contain sharp edges. Handle the rotors carefully because edges

may be sharp. Wear gloves while installing and servicing the pump to help avoid injuries from these haz-

ards.

18. Never touch the gear case during operation. The surface temperature may exceed 110°F (43°C). The pump cover and body may be cold or hot depending on the product (CIP at 190°F (88°C) or 300°F (149°C) product, for example).

19. Never touch the motor or motor shroud (if supplied) during operation, as it can become very hot.

20. When moving the pump, use appropriate lifting devices. Attach lifting devices to the eye bolts on the gear case; the gear case has holes for attaching lifting eye bolts. Always use securely fitted lifting straps when lifting with a crane or similar lifting gear. See "Lifting" on page 17.

Waukesha Cherry-Burrell® Brand Universal 3 Pump Care of Component Materials

WARNING

Care of Component Materials

NOTE: SPX FLOW recommends the use of an FDA-approved anti-seize compound on all threaded connections.

Failure to comply with the Care of Component Materials could lead to bodily injury.

Stainless Steel Corrosion

Corrosion resistance is greatest when a layer of oxide film is formed on the surface of stainless steel. If film is disturbed or destroyed, stainless steel becomes much less resistant to corrosion and may rust, pit or crack.

Corrosion pitting, rusting and stress cracks may occur due to chemical attack. Use only cleaning chemicals specified by a reputable chemical manufacturer for use with 300 series stainless steel. Do not use excessive

concentrations, temperatures or exposure times. Avoid contact with highly corrosive acids such as hydroflu-

oric, hydrochloric or sulfuric. Also avoid prolonged contact with chloride-containing chemicals, especially in presence of acid. If chlorine-based sanitizers are used, such as sodium hypochlorite (bleach), do not exceed concentrations of 150 ppm available chlorine, do not exceed contact time of 20 minutes, and do not exceed temperatures of 104°F (40°C).

Corrosion discoloration, deposits or pitting may occur under product deposits or under gaskets. Keep surfaces clean, including those under gaskets or in grooves or tight corners. Clean immediately after use. Do not allow equipment to set idle, exposed to air with accumulated foreign material on the surface. Corrosion pitting may occur when stray electrical currents come in contact with moist stainless steel. Ensure all electrical devices connected to the equipment are correctly grounded.

Alloy 88

Waukesha Alloy 88 is the standard rotor material for Universal 1, Universal 2, Universal 3, Universal TS, Uni-

versal Lobe, Universal 420/520, and 5000 Series Rotary PD pumps. This alloy was developed specifically for

corrosion resistance and close operating clearance requirements of high performance rotary positive displacement pumps. Alloy 88 is a nickel based, corrosion-resistant, non-galling or seizing material. The ASTM desig-

nation is A494 Grade CY5SnBiM (UNS N26055), and the material is listed in the 3-A Sanitary Standards as acceptable for product contact surfaces.

The corrosion resistance of Alloy 88 is approximately equal to AISI 300 Series Stainless Steel. However, Alloy 88 has limited resistance to certain aggressive chemicals that may be commonly used in contact with AISI 300 Series Stainless Steel.

Do not use Alloy 88 in contact with nitric acid. Nitric acid is commonly used to passivate new installations of stainless steel equipment. Do not allow nitric acid based passivation chemicals to contact Alloy 88 rotors. Remove the rotors during passivation and use a separate pump to circulate the passivation chemicals. Also, if nitric acid-based CIP cleaning chemicals are used, remove the rotors prior to CIP cleaning and clean them separately by hand in a mild detergent. If you have questions regarding other aggressive chemicals, please contact SPX FLOW Application Engineering for assistance.

Elastomer Seal Replacement Following Passivation

Passivation chemicals can damage product contact areas of this equipment. Elastomers (rubber components) are most likely to be affected. Always inspect all elastomer seals after passivation is completed. Replace any seals showing signs of chemical attack. Indications may include swelling, cracks, loss of elasticity or any other noticeable changes when compared with new components.

Introduction

Pump Receiving

The pump contains internal moving parts. DO NOT put hands or fingers into the pump body ports or drive area at any time during operation. To avoid serious injury, DO NOT install, clean, service, or repair the pump unless all power is off and locked out.

All ports are covered at the factory to keep out foreign objects during transit. If covers are missing or damaged, remove the pump cover (if damaged) and thoroughly inspect the fluid head.

Be sure that the pumping head is clean and free of foreign mate-

rial before rotating the shaft.

Each standard Waukesha Cherry-Burrell brand pump is shipped completely assembled and lubricated. Review “Operation” on page 26 before operating the pump.

Intended Use The Universal 3 Series Rotary Positive Displacement Pump is

exclusively intended for pumping liquids, especially in food and beverage installations.

Refrain from using the pump in a manner which exceeds the scope and specifications stated in this manual.

Any use exceeding the margins and specifications set forth is considered to be not intended.

SPX FLOW is not liable for any damage resulting from such activities. The user bears the full risk.

Improper use of the pump leads to:

- damage

- leakage

- destruction

- potential failures in the production process

Equipment Serial Number All Waukesha Cherry-Burrell brand pumps are identified by a

serial number on the gear case nameplate, which is stamped on the pump body and cover.

The gear case, body, and cover must be kept together as a unit due to backface, rotor, and cover clearances. Failure to do so will damage the pump.

Pump max temperature is 300°F (149°C).

Operating temperatures depend on the rotor style used. See the rotor descriptions below.

Max. RPM

Rotor Style Recommended for use with liquid temperatures between:*

Low Viscosity Rotors -40°F (-40°C) to 180°F (82°C)

Standard Clearance Rotors -40°F (-40°C) to 300°F (149°C)

316SS Clearance Rotors -40°F (-40°C) to 200°F (93°C)

* Contact SPX FLOW Application Engineering for higher pressures or higher temperature applications.

Operating the pump outside the stated operating parameters may result in severe personal injury or death.

"Low Viscosity" rotors may be used with liquid temperatures up to 180°F (82°C).

Between 160° (71°C) and 200°F (93°C), consider other application factors, such as; speed of operation, differential pressure, lubricating properties of liquid being pumped, and product viscosity. If these factors trend toward a difficult application (high speed, high pressure, non-lubricating) then "Standard" clearance rotors are recommended.

"Standard" clearance rotors are recommended for use with liquid temperatures between -40°F (-40°C) and 300°F (149°C). They provide additional clearance in the front face area plus rotor to body areas. Because of this additional clearance there is more slip (inefficiency) with low viscosity liquids, which the pump must overcome with higher operating speed (rpm.) VHP (viscous horsepower) is slightly lower when using standard clearance rotors. Standard clearance rotors are also used when the product viscosity is above 200 CPS.

"316SS" clearance rotors are made from 316 stainless steel material (in place of standard non-galling alloy

88) and recommended for use at temperatures up to 200°F (93°C). These rotors provide additional clearance

all around (more than Standard clearance alloy 88 rotors) to ensure no running contact between the 316 SS rotors and other 316 SS pump components. Because of this additional clearance, there is more slip (inefficiency) with low viscosity liquids, which the pump must overcome with higher operating speed (rpm). VHP (viscous horsepower) is slightly lower when using "316SS" clearance rotors.

NOTE: Consult SPX FLOW Technical Services for applications near 300°F (149°C) or above 200°F (93°C) with 316SS rotors. For clearance data, see Table 18, “Rotor Clearances,” on page 91.

CAUTION

WARNING

Install Connections and Piping

These pumps are positive displacement design and will be severely damaged if operated with closed valves in discharge or inlet lines. The pump warranty is not valid for damages caused by a hydraulic overload from operation or start-up with a closed valve in the system.

Piping Support

To minimize forces exerted on the pump, support all piping to the pump independently with hangers or pedestals. Such forces can cause misalignment of the pump parts and lead to excessive wear of rotors, bearings, and shafts.

Figure 8 shows typical supporting methods used to independently support each pipe, reducing the weight effect of piping and fluid on the pump.

Do not exceed 50 lb (22.7 kg) load on pump inlet or discharge ports. Exceeding this limit may cause damage to the pump.

Figure 8 - Piping Support

Figure 9 - Flexible Connections and

Supports

Recommended

Figure 10 - Pump Below Supply

NOT recommended

Expansion Joints

Thermal expansion of piping can cause tremendous forces. Use thermal expansion joints to minimize these forces on the pump.

Flexible joints can be used to limit transmission of mechanical vibration. Ensure that the free ends of any flexible connections in the system are anchored.

Inlet Piping

Install the pump below the supply liquid level to reduce the air in

the system by flooded suction, to prevent the pump from becom-

ing air-bound (Figure 10).

If the pump is installed above the supply liquid level, the piping on the inlet side must slope up toward the pump, preventing air pockets in the pipes (Figure 11).

Recommended

A. Inlet Check Valve B. Foot Check Valve

Figure 12 - Inlet Check Valve

Discharge Side

For systems with liquid under a vacuum, install a check valve on

the discharge side of the pump. The check valve prevents back-

flow (air or fluid) to aid in the initial start-up by minimizing the required differential pressure supplied by the pump to start the flow (Figure 13).

NOTE: Make sure the inlet flow is not restricted. Don’t start the pump deadheaded, e.g., operated with no flow through it.

Pressure and vacuum gauges provide valuable information about pump operation (Figure 15). Wherever possible, install the gauges to help provide information on the following:

• Normal or abnormal pressures

• Indication of flow

• Changes in pump condition

• Changes in system conditions

• Changes in fluid viscosity

Inlet Side Strainers and Traps

Inlet side strainers and traps (Figure 19, items A and B, respec-

tively) can be used to prevent foreign matter from damaging the pump.

Select carefully to prevent cavitation caused by the restriction of

the inlet. If inlet strainers are used, they must be serviced regu-

larly to prevent clogging and flow stoppage.

A. Strainer B. Magnetic Trap

Figure 19 - Inline Strainers and Traps

CIP (Clean-In-Place) Design

In order to avoid temperature shock after the introduction of hot CIP fluid, stop the pump before filling the pumphead with hot CIP fluid. Once the hot CIP fluid has

filled the pumphead, allow up to 15 min-

utes for the pump fluid components to thermally expand, then re-start the pump.

NOTE: Depending on pump model, pipe size, fluid properties, and rotor clearance, some configurations will not supply sufficient flow rate to achieve the required line velocity of 5 ft/sec (1.5 m/s) for CIP. Upon installation, check the line velocity for each specific application. If the velocity is not sufficient, add a booster pump in line in order to reach the required velocity. Contact SPX FLOW Application Engineering for further questions.

The design of the Universal 3 provides complete access of the CIP solution to all product contact surfaces:

• The flat body profile (minimum requirement for standard CIP installations) allows complete draining of the side-mounted pump (see Figure 2 on page 13), and provides the CIP solution access to the entire profiled cover gasket groove.

• Flats on the rotor hubs provide solution access to the cover hub/shaft seal areas for difficult cleaning applications.

Guidelines

Use the following guidelines when designing and installing the CIP system to ensure successful cleaning:

• Ensure that the velocity rate of CIP solutions is adequate to clean the entire circuit. For most applications, a velocity of 5 ft/sec (1.5 m/s) is sufficient. For the CIP solution to achieve the proper velocity, the pump drive must have enough speed range and horsepower. The required inlet pressure also must be satisfied. If the pump does not supply enough CIP solution velocity, a separate CIP supply pump with an installed bypass may be used. To determine the appropriate bypass arrangement, contact SPX FLOW Application Engineering.

• Make sure that a differential pressure is created across the pump. Differential pressure will push CIP solutions through close-clearance areas of the pump, resulting in better cleaning action. The high pressure side may be either the inlet or outlet side. 30 psi (2 bar) is the minimum required differential pressure for most applications. For difficult cleaning applications, higher pressure or longer cleaning cycles may be required.

• The pump must be operated during CIP to increase turbulence and cleaning action within the pump.

NOTE: Make sure to jog the rotors during draining to ensure that all fluid drains from the seal area.

Page 22 95-03103 11/2018

• If complete draining is required, the pump must be in the side mount position.

Pumps with double seals require flushing.

The flush media (water or lubricating fluid compatible with the product) must be connected and flowing whenever the pump is operated.

Operating the pump without flush will damage the seal and pump parts due to excess heat from dry running.

Check for buildup or restrictions (kinking) in the flush lines or fittings at regular intervals. SPX FLOW recommends using clear (transparent) flush lines for easier observation.

Two 1/8-inch female pipe thread (NPT) flush connections are located in the seal housing pieces.

1. Connect the flush inlet to the lower connection, and the outlet

to the upper connection, to flood the flush area completely (Figure 20).

2. Connect the flush outlet for unrestricted flow to the drain.

NOTE: As shown (ports horizontal), if steam is used as a flush media, connect the inlet at the upper connection, and the outlet at the lower connection to ensure condensation removal (Figure 21). If steam condensate is used as a flush media, connect the inlet at the lower connection, and the outlet at the upper connection (Figure 20). See note under Figure 22.

3. Use cool, filtered flush media to obtain maximum service life

of the seal components. If the pumped product is sticky or solidifies at room temperature, use warm or hot flush media.

0.8 gpm (1.9-3.0 l/m).

NOTE: The difference between the product-side pressure and the flushing pressure must not exceed 102 psi (7 bar).

5. Also install a solenoid valve in the flush supply and wire it in

series with the motor starter to provide an automatic start/ stop of the flush media flow before the motor turns on and after the motor turns off.

Double O-Ring Seals

1. Set flow rate of approximately 1/4 gpm for most applications.

For high temperature applications, increase flow.

2. Flushing media is restricted on the inlet side and has free

flow to drain on the outlet side.

3. Typical flushing connections are 1/8" NPT female pipe taps.

NOTE: For O-ring seals, the maximum product pressure is 100 psi (7 bar).

Check Coupling Alignment Pumps and drives ordered from the factory and mounted on a

common base plate are aligned before shipment. Alignment must be re-checked after the complete unit has been installed and piping completed. Periodic re-checking is advisable during the pump service life.

• SPX FLOW recommends using a flexible coupling to connect the drive to the pump. Several different types are available,

Figure 24 - Lovejoy Coupling

Coupling

including couplings with slip or overload provisions. SPX FLOW provides Lovejoy (Figure 24) or T.B. Woods

25) couplings unless otherwise specified when ordering. Flexible couplings can be used to compensate for end play and small differences in alignment.

• Align the pump and drive shaft as closely as possible:

• Pump and Drive are factory aligned.

• Re-check alignment after installation and before start-up.

• Re-check alignment periodically, to maximize service life.

Maintenance Inspections

Detecting wear in the early stages can reduce repair costs and down time. A simple “look-feel” inspection of the pump during breakdown cleaning is recommended to detect signs of trouble at an early stage.

A detailed maintenance inspection should be scheduled annually. See “Annual Maintenance” on page 31.

Refer to the “Maintenance Inspection Chart” on page 32 for pos-

sible causes and solutions to common issues discovered during inspection.

Inspection of Rotor Tips

Remove the cover (see “Remove Cover” on page 34) and check for metal-to-metal contact between the rotor wings. When contact is detected, repair or replace the pump.

Figure 31 - Rotor to Rotor Tip

Clearance

Figure 32 - Shaft and Rotor Inspection

Visually inspect the rotors for rotor tip to rotor tip contact and rotor tip to rotor hub contact. Manually rotate the pump drive shaft and

ensure that the rotor tip clearance is equal on both sides as indi-

cated in Figure 31.

Inspection of Shaft and Shaft Shoulder

Visually inspect the shaft for twists or bends; replace it as neces-

sary. Visually inspect the shaft shoulder (Figure 32, item C) for excessive wear; replace it as necessary. If the shaft shoulder has a sharp edge, remove the edge with a file to prevent cutting the shaft O-ring on installation.

Inspection of Rotor

Visually inspect the rotors for worn splines (Figure 32, item A) and hub wear at the rotor stress points (see arrows in Figure 33

Inspection of Gears and Bearings

Gear backlash

With the fluid head and seals removed, feel for gear backlash by

rotating either shaft by hand. The other shaft must engage imme-

diately. Perform this check three times at 60-degree intervals. If play (backlash) is evident, remove the gear case cover, check the gear teeth for wear, and ensure that the gear is not loose on the

Figure 33 - Backlash Check

shaft. If the gear teeth are worn, replace the gears. If the gear is loose on the shaft, inspect the shaft key and keyway; replace as necessary.

Check bearing condition

With the fluid head and seals removed, check the bearing condi-

tion by applying (by hand) an up or down force of approximately

30 lbs (14 kg). If movement is detected, the bearing may be fail-

ing. Also check the shaft movement forward or backward. If the bearing is failing, replace the bearing and review the lubrication section starting on page 29.

Figure 34 - Bearing Deflection Check

Annual Maintenance

At least annually, perform the procedures and corrective measures outlined in “Maintenance Inspections” on page 30, in addi-

tion to the following preventive maintenance:

• Check the bearings with a dial indicator for shaft radial play. If

the deflection is equal to or greater than the rotor-to-body diametrical clearance (see “Checking for Proper Clearance” on page 90), replace the bearings.

• Remove the gear case cover and inspect the gears for wear,

backlash and looseness. Loosen and torque the gear retaining nuts to the proper torque.

• Thoroughly inspect the rotors for worn splines, hub wear and

stress cracks (see arrows in Figure 35). Use the dye check method to detect any fatigue-type cracks at rotor stress points.

• Review the performance record on the pump, and check the

radial and backface clearances to determine wear and effect on performance. Adjustment to the operating speed can compensate for wear in some applications.

When bearings or shafts are replaced in the field, take care to correctly position the shaft by shimming it to maintain sufficient running clearances between the rotor wing faces and the pump body faces (backface and cover face). It is important to hold the

Figure 35 - Rotor Stress Points

same backface dimension for both rotors, within 0.0005” (0.0127 mm), to avoid crossover interference.

To disassemble the fluid head, see Cover and Rotors” on page 34. Remove and clean the cover Oring, pump seals, and the rotor nut assembly. Inspect and replace them as necessary.

“Fluid Head Disassembly -

NOTE: Always replace the rotor nut O-rings and product-side seal O-rings when reassembling the pump. If the area behind these seals becomes soiled, contact SPX FLOW Application Engineering for a specific cleaning and sanitizing procedure validated to remove bacteria. If a chlorine solution (200 ppm available chlorine) is used, it should leave no residual deposits which would remain in the pump.

Acid cleaners have a much higher metal corrosion rate and pump parts should remain in acid cleaning solutions no longer than necessary. Any strong inorganic mineral-based acids that are harmful to your hands would be harmful to pump parts. See “Stainless Steel Corrosion” on page 11.

In applications where material can harden in the pump during shutdown, a CIP cleaning, flush, or disassembly of the fluid head and manual cleaning is strongly recommended. See “CIP (CleanIn-Place) Design” on page 22.

Front Bearing Assembly

SPX FLOW PD Precision Pumps require bearing assemblies with very tight internal tolerances. In fact, the internal tolerances of “off-the-shelf” bearings can be many times larger than required. Although they are considered in-spec in the bearing industry, they can cause internal damage within an SPX FLOW PD Pump.

SPX FLOW’s proprietary bearing “MATCHING” process starts with top quality bearing assemblies, then sorts, measures, pairs,

Figure 200 - Grease Shaft

Figure 201 - Bearing assembly

A. Lower Cone / Roller Assembly B. Inner Spacer C. Lower Cup D. Outer Spacer E. Upper Cup F. Upper Cone / Roller Assembly

grinds and adds spacers to them to ensure the matched bearing sets meet the required tight internal tolerances.

SPX FLOW bearings can be cross-referenced and appear to be the same, but competitive bearings are omitting the Matching

process, which is imperative to achieve the required internal toler-

ances. Once a bearing set is matched, it must remain together as a set for the life of the pump, in order to maintain the tight internal tolerances.

NOTE: The following instructions cover the assembly of a sixpiece front bearing assembly. For a four-piece assembly, only one spacer and cup is used.

1. Lubricate the front bearing area of the shaft (Figure 200, item

7, 8) with anti-seize. Place it upright in a hydraulic press with the liquid end down.

2. Unwrap the front bearing assembly.

PD100-645

Figure 202 - Press Lower Cone onto

Shaft

NOTE: DO NOT interchange the parts of one bearing

assembly with another. The parts are precisely matched during manufacturing and must be installed as a matched assembly. See Figure 201.

3. Lift the lower cone and roller assembly (Figure 202, item A)

out of the bearing stack and place it on the shaft with the radius facing down. Press it onto the shaft until it is seated against the shaft shoulder. Press only on the inner cone.

4. Place the inner spacer (Figure 203, item B) over the shaft

onto the lower cone and roller assembly.

5. Place the lower cup (item C) over the lower cone and roller

assembly, keeping the cup opening toward the assembly.

6. Place the outer spacer (item D) over the shaft and onto the

1. Unwrap the rear bearing assembly.

NOTE: DO NOT interchange the parts of one bearing assembly with another. These parts are precisely matched during manufacturing and must be installed as a matched assembly.

• For models with ball bearing assemblies: Lubricate the shaft bearing area with anti-seize, then press the bearing into place. The shielded side of the bearing fits against the bearing spacer. Press only on the inner race.

• For models with tapered roller bearing assemblies: Lubricate the shaft bearing area with anti-seize. Follow the “” procedures starting on page 85.

NOTE: Heating the bearings is NOT recommended. If bearings are heated, do not exceed 300°F (149°C).

NOTE: Do not install bearing retainer sealant, gears, or gear locknuts until the correct shimming has been verified.

2. If the shafts and/or bearings do not need to be replaced and the shims are marked indicating the shaft and bearing they are matched with, a shim adjustment probably

will not be necessary. Reuse the existing tagged shims, shafts and bearings in the same gear case bores.

3. If existing shims are lost and/or a standard shaft is used, determine the required shims from the chart.

4. If it is necessary to calculate the required shims for replacement shafts, bearings or both, refer to Figure 207 and Figure 208; carry measurements and calculations to three decimal places (e.g. 0.059).

5. Determine the shim thickness required for the front bearing:

• Measure “B” in the gear case and “C” on the shaft (Figure

207).

• Measure “D” and “E” on the body (Figure 208).

• Determine the proper backface clearance. Refer to

Table 18, “Rotor Clearances,” on page 91.

• Required Shims = Backface clearance - C + B + D - E.

6. Place the shims in the gear case, resting against the shoulder in the front bearing bore. (See Figure 207.)

Install Shaft

1. With the shims in place, install the shaft assembly in the front bearing bore with the fluid end facing up. Ensure that the shaft is installed in its original location.

NOTE: The shafts may need to be removed for a final shim adjustment.

2. Lubricate the outside diameter of the bearing.

3. Press the shaft into place until it is seated against the shim pack. Press only against the outer race of the bearing.

NOTE: A tube of the same diameter as the outer race of the bearing also can be used to press the shaft into place.

4. Temporarily secure the shaft/bearing in place with bearing

retainers to aid in checking the clearances. DO NOT install silicone sealant at this time.

5. The bearing retainer (Figure 209, item B) must rest firmly against the bearing. Leave a 0.010 to 0.050 in (0.25 to 1.25 mm) clearance between the back of the bearing retainer and the front of the gear case (Figure 209, item A). If this clearance is not met, place shims between the bearing (Figure 209, item C) and retainer.

Figure 210 - Measure Clearance

6. Temporarily mount the body on the gear case.

7. Secure the body to the gear case using the body retaining screws.

8. Install the rotors and rotor nuts. Rotor nut O-rings and retainer O-rings are not required at this time.

9. Measure the rotor backface clearance (Figure 210, item A) through the port or from the front. The backface clearance for both rotors must be the same to prevent rotor crossover contact and must be ±0.0005" of the value found in Table 18, “Rotor Clearances,” on page 91.

10. Check the rotor front face clearance (Figure 210, item C).

11. Check the rotor to body clearance (Figure 210 and Figure 211, item B).

12. Check the clearances against Table 18, “Rotor Clearances,” on page 91. For other non-standard rotors, check with customer service.

NOTE: If the process uses special clearance rotors, contact customer service with the serial number of the pump for clearance tolerance values.

NOTE: “B” dimension is below the face of the casing.

13. If the backface clearance is not met, disassemble the pump and adjust the shimming to achieve the correct backface clearance.

14. If the rotor to body clearance is not met or is uneven, contact SPX FLOW Application Engineering for proper adjustment procedures.

15. After obtaining proper clearance, remove the rotor nuts,

Install Timing Gears

1. Place the gear keys into the shaft key slots. Angle the keys

out for easier installation of the gears.

NOTE: To aid in timing setup, rotate the rotors until they are at right angles to each other before installing the gears.

2. Slide the spur drive gear onto the drive shaft. The spur drive

gear has one punch mark on the gear.

3. Slide the short shaft gear onto the short shaft. The short shaft

gear has two punch marks on the gear. Straddle the single punch mark of the spur drive gear with the two punch marks on the short shaft gear (Figure 214).

4. Use a wood or nylon block (Figure 215, item A) to keep the

shafts from turning. If a block is not available, use rags to block the gears, or with one rotor on the shaft, block the rotor with a nylon dowel.

5. Slide the lock washers onto the shaft. Lubricate the threaded

area on the shafts and face of the locknuts with oil or grease.

NOTE: It is generally best to keep backface clearance to a minimum.

Checking for Proper Clearance

Waukesha Cherry-Burrell brand pumps are designed with close running clearances. Backface clearances are set with shims

Backface clearance for both rotors must be equal to avoid crossover interference with the adjacent rotor hub.

during assembly.

Shafts are positioned with shims behind the front bearing and locked into gear case with the bearing retainers. Rotors lock against the shaft shoulder. Clearance between the body backface and the back of the rotor wing is called backface clearance.

1. To check backface clearance, first mount the body (less seals) onto the housing. Assemble the rotors and secure them with rotor jam nuts.

2. With feeler gauges, measure the rotor backface clearance (Figure 218, item A), through the port or from the front.

3. Measure the rotor front face clearance (Figure 218, item C).

4. Measure the rotor to body clearance (Figure 218, item B).

5. Check the measured clearances against Table 18, “Rotor Clearances,” on page 91.

6. Make corrections as required and follow examples in Table 19, “Backface Clearance Corrections,” on page 91, to determine the exact adjustment to make and to avoid unnecessary assembly/disassembly.

7. To make shim adjustments, first remove the rotors, body and shafts. Make the required shim adjustment and reassemble. (Figure 218, item D is the front bearing rear shim.)

8. Re-check the backface clearances. Be sure both rotors have the same clearance to avoid crossover interference with the
