SHURflo Heavy-Duty Cast Iron and Bronze Rotary Close-Coupled External Gear Pumps

Refer to form L-4082 for General Operating and Safety Instructions and Applicable Warranty.

Description

SHURflo self-priming, positive displacement, rotary external gear pumps provide a nearly pulseless flow. Standard models are mounted directly to NEMA frame AC Open Drip-Proof (ODP) motors using an easy-installation package, or as pump heads only for custom installations. Standard safety pressure relief valve that is included can be ported internally or externally. Single-phase motors are thermally overload protected; 3-phase ODP motors are not.

Uses: Handle a wide range of industrial, marine, agricultural and commercial applications where non-abrasive and non-particulated fluids compatible with pump wet-end construction component materials are pumped.

• Capacities up to 24.8 GPM.

• Maximum pressure to 125 PSI and working casing pressure to 200 PSI.

• Max. RPM: 1725.

• Suction lift to 19.5 ft.

• Mechanical seals (Viton or Buna) with carbon on ceramic faces with engineered flush chamber for internal or external flush to handle viscosities beyond 2000 SSU.

• Pumps with electric motors are configured to handle up to 500 SSU and 125 PSI at 1725 RPM or run at reduced speeds to handle a wide range of pump fluid viscosities and specific gravity up to 100,000 SSU. (Maximum torque loads are found in the performance chart.)

• Pumps can operate bi-directionally (reversible).

• Temperature ranges from -20° to 280° F.

• Standard adjustable pressure relief valves that can be internally or externally ported are standard.

BRONZE MODELS – Excellent for water-based fluids. Ryton PPS (Polyphenylene Sulfide) spur gears provide quiet operation and chemical compatibility. No metal-to-metal contact. Pumps also have 303 stainless steel shafts and carbon graphite bushings. Buna-N mechanical seal with temperature range of -20° to 210° F. Wet-end parts are constructed from bronze, brass, Ryton PPS, stainless steel (17-7, 303 and/or 18-8),

CAST IRON MODELS – Specifically designed to be used with oil-based fluids, not to be used with water-based fluids. Pumps include steel spur gears with steel shafts and cast iron shaft support. V parts are constructed from cast iron, steel, stainless steel (17-7, 303 and/or 18-8), vellumoid, carbon, ceramic and Viton.

REPAIR SEALS AND OPTIONS – Standard seals are Viton and Buna-N with carbon on ceramic faces. Standard seals can be located in the repair parts list pages in this manual. When switching between V the matching o-rings in the same material. These can be found in the repair parts list pages in this manual.

Optional Close-Coupled Gear Speed Reducers are available that mount directly between pump and motor to reduce pump speed for high viscosity or high specific gravity applications (See Appendix 2).

NOTE: This series of gear pumps is also available as pedestal models for custom installation. They are not equipped with motors.

vellumoid, graphite, carbon, ceramic, and Buna-N.

iton and Buna-N mechanical seals, be sure to order

WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable

and/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in a room or area designated for that purpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniques and cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warning could result in personal injury and/or property damage.

NOTES: Pumps with motors are HP rated to handle up to 500 SSU at 125 PSI and specific gravity of 1.0.

Max. PSI = 125 Max. Viscosity = 500 SSU at 1725 RPM with standard spur gears Max. RPM = 1725 Max. Specific Gravity = 1.1 at 125 PSI, up to 1.6 at lower PSI & viscosity. Max. Input Torque = See chart above. Reverse Rotation = Pumps are equipped with pressure relief valves and can be run in reverse rotation; however pump is reversed unless pump relief valve cover is rotated 180 The pump relationship between volume (GPM), pressure (PSI), speed (RPM) and horsepower is shown on performance chart in Shurflo Motor Manual form L-4082. When pumping a more viscous liquid, a slower speed, a larger pipe size pump, and possibly a larger motor should be selected.

Check motor.

It may be equipped with an automatic resetting thermal protector and may restart unexpectedly (see specifications chart). Protector tripping is an indication of motor overloading as a result of operating the pump at too high a pressure (over 125 PSI), too high of viscosity, too high of specific gravity, excessively high or low voltage, inadequate wiring, incorrect motor connections, too small a motor (sized incorrectly, not enough HP), or a defective motor or pump.

Do not handle pump with wet hands or when standing in water. Failure to follow the General Safety Information and all warnings could result in fatal electrical shock!

Assembly

If pump and motor are

( pre-assembled, skip assembly.)

. Two styles of motor to pump shaft

couplers are manufactured but only one is shipped with each pump. See Figures 3 & 4 to identify which coupler you have.

2. Apply anti-seize compound to the entire length of the motor shaft and drive coupling spline teeth.

3. If you have a Type B coupler, install the rubber plug (See Figure 4) into the bottom of the motor shaft bore in the drive coupling.

4. Align the keyways of motorshaft and coupling, then install the key (See Figure 3 or 4). Slide the drive coupling onto the motor shaft as far as it will go.

NOTE: Some models are supplied with a bushing and extra key (not shown), which converts the drive coupling from a 7/8" motor shaft bore to a 5/8" motor

s the motor shaft bore of the coupling if needed.

5. Install the set screws into the coupler and tighten the set screws

ecuring the coupler, key and motor

s shaft together. For Type B collar, ensure the collar set screws line up over the key and it is flush with the back edge of the coupling prior to tightening (See Figure 4).

6. The coupling is now ready for final pump motor assembly.

7. Make sure the splines are coated with anti-seize compound or grease. Slide the male spline shaft on the pump head into the female spline now mounted on the motor shaft. The pump head will pivot on the motor.

8. Secure the pump to the motor with four bolts.

9. The unit is ready for operation.

Installation

MPORTANT:In any installations where

property damage and/or personal injury can occur when the pump is not operating due to power outages, discharge line freezing, or any other reason, a back-up system(s) and/or warning system(s) should be used.

In order to safely use this product, familiarize yourself with this pump and also with the liquid (chemical, etc.) that is going to be pumped through the unit. This pump is not suitable for many liquids.

1. Locate the pump as close to the liquid source as possible, making the suction line as short and direct as possible.

PIPING

SUCTION

2. Avoid excessive lengths or number of fittings and bends in the suction line.

3. Attach suction line to suction inlet.

4. It is recommended that same size pipe as pump ports be used or, in cases requiring lengthy piping, the next larger size pipe be used.

5. If suction lift is greater than what is indicated in the performance chart, attach a foot valve below liquid level at end of suction line to ensure positive priming. Also note: If fluid specific gravity is greater than 1.4 or viscosity greater than 500 SSU, a foot valve is also recommended.

NOTE: If a foot valve (or check valve) is not used in the suction line, it may be necessary to refill the pump every time the unit is stopped and you wish to restart the pump. This depends on the length of time between starts and whether or not the gears are wet enough to close cavities to af

6. in a liquid, place a filter in the suction line.

fect a prime.

7. Be certain all suction piping connections are airtight.

NOTE: Assure airtight pipe connections with the use of a pipe joint sealant.

ISCHARGE

8. Attach discharge piping to the discharge outlet.

Support pump and

piping during assembly and after installation. Failure to do so may cause piping to break, pump to fail, motor bearing failures, etc., all of which can result in property damage and/or personal injury.

NOTE: Should the pump need to be self-draining, the pump head should be mounted in the vertical position with the suction port facing down. When pumping high viscosity fluids, the vertical position can be used with the suction port facing up and the pump mounted under the source. Increasing the suction pipe size and eliminating bends and elbows also assists in pumping high viscosity fluids. Max. viscosity is 500 SSU at 1725 RPM.

9. If a shut-off valve or handgun is required in discharge line, provide a pressure relief valve for pump protection.

Shutting off discharge

without providing pressure relief can cause extreme over pressure which can result in pump and/or motor failure. Do not exceed 125 PSI pump or system pressure.

10. Operation under shut-off discharge

conditions will overheat and damage pump.

NOTE: Globe valves or other restrictive valves should not be used as shut-off mechanism as they are restrictive in nature and will seriously affect pump performance.

11. After all piping and controls (not sup-

plied with unit) have been installed, unit is ready for operation.

Operation

Do not run pump

dry, as permanent damage to the pump gears, seal, and bearings will result. Suction pressure should never be greater than the discharge pressure.

1. All pumps must be primed before start-up and the seal chamber needs to be filled (See Figure 5). Never operate a pump unless it is secured to a solid foundation and all safety shields are installed.

Remove plug and fill seal chamber with fluid and reinstall plug

Figure 5 - Prime Plug

Upon start-up, maintain a minimum of 15 PSI (1 BAR) operating pressure on the pump. This will allow any remaining air to be driven from the seal chamber and will ensure liquid circulation to the mechanical seal.

2. Gear pumps are built to very close tolerances and this tolerance must not be altered. The liquids must, therefore, be free of all abrasives. Sand, silt, wettable powders, etc. must be avoided.

NOTE: Cast iron pumps are for oil-based fluids only.

When pumping a more viscous

3. (beyond 500 SSU) liquid; a slower speed, a larger pipe size pump, and possibly a large motor should be selected.

NOTE: See performance chart for Max. Torque.

4. Recheck motor and pump rotation. Proper pump rotation is clockwise (CW) looking at the front of the pump when pressure relief valve is

Operation (continued)

nstalled by manufacturer (See

i Figure 1).

. On all standard models, pressure

relief valve is always on discharge side (See Figure 1).

PRESSURE RELIEF VALVE

6. Standard model rotary gear pumps are supplied with a built-in internal pressure relief valve (can be externally ported). The valve may be adjusted and used to set system operating pressure, or used as a system pressure relief valve to prevent pump and motor damage that can occur when discharge line is closed off. This relief valve is not factory set. Extended operation (over one minute) under shut-off conditions could cause pump to overheat, leak, and damage itself or overload motor.

7. To increase the pressure relief valve pressure setting, loosen lock nut (See Figure 12, Ref. No. 37), then turn the set screw (See Figure 12, Ref. No. 36) in (clockwise). Turning the set screw out (counterclockwise) will reduce the pressure setting. When desired pressure is achieved, tighten lock nut and reinstall protective cap (See Figure 6).

Loosen valve lock nut and adjust pressure with adjustment screw

and tighten lock nut again.

Figure 6 - Pressure Relief Valve Adjustment

The pressure relief valve can be

8. converted to an external relief. This will allow the relief to dump back to tank and allow longer periods of relief without pump damage.

Remove external bypass

lug cover and discard.

p then insert external bypass

relief plug as shown.

Figure 7 - External Pressure

Relief Valve Installation

However, this is not a full-line relief valve, and in cases where frequent extended relief valve operation is anticipated, a full-line external relief valve should be piped in the discharge line and connected either back to the tank or well downstream of the pump suction inlet (See Figure 7).

9. To convert the relief valve to external relief, remove the NPT pipe plug from the pump cover (See Figure 12, Ref. No. 36) and discard. This plug is next to the relief valve. In the bottom of the NPT hole, there is a second drilled and tapped hole. An optional external bypass plug (See Figure 12, Ref. No. 39 included) should be inserted in this hole and bottomed out. The open NPT port must now be piped back to the tank or well downstream of the pump suction (See Figure 7).

10. Standard models are equipped with pressure relief valves, and the pump can be run in reverse, however, the pressure relief valve will not function. For continuous reverse rotation, the cover plate must be rotated 180˚. This is accomplished by removing the eight cover plate screws, rotating the cover plate, and reattaching the screws. The pressure relief valve should now be on the opposite side. This will allow operation of the pump with a functioning pressure relief valve in reverse rotation.

GEAR PUMP GASKET ADJUSTMENT FOR TEMPERATURE (See Appendix 1)

11. For operation in fluid temperatures above 120° F, bronze pump models must have the gasket thickness

djusted (not necessary for cast iron

a models). Use Appendix 1 to identify pump, temperature and gasket recommendations for adjusting the cover clearance prior to operation in elevated temperatures or viscosities above 500 SSU.

Failure to adjust pump

cover clearances for operating temperatures above 120° F will result in severe pump and/or motor damage.

NOTE: When pumping fluids of high viscosity (>500 ssu), the required torque and HP can be reduced by adding a gasket for increased gear clearance.

MECHANICAL SEAL FLUSH INSTALLATION OPTIONS

12. These bronze and cast iron pumps

are equipped with mechanical seals and have been designed with flush ports because mechanical seals require cooling lubrication for long life.

a. For fluids with viscosities less than

2000 SSU, a flush is not necessary, but the seal cavity must be prefilled with either the operating fluid or a neutral fluid. This is to ensure seal cooling and lubrication during start-up (See Figure 5).

Failure to provide

initial seal prime can result in the mechanical seal overheating with resulting repair costs.

b. For high viscosity fluids, a flush

will be necessary

. The seal must be cooled and lubricated by a fluid. In the case of high viscosity fluids, due to the precision clear

ances between the gear teeth and the bronze or cast iron body, highly viscous fluids will not be able to adequately relieve the air

in the seal cavity on start-up. The dry running of a mechanical seal will cause rapid failure. A flush must be provided for fluids with a viscosity of greater than 2000 SSU.

Pumping fluids with

viscosities greater than 2000 SSU requires flushing the seal chamber during operation, otherwise seal damage will occur.

EXTERNAL FLUSH

An external flush system is typically recommended for applications where crystallization build-up on the seal is possible. Some dilution of the working material must be acceptable to use an external flush system.

The external flush system (See Figure 8 for typical installation) is commonly used with liquids where city water can be used as the neutral flush fluid. City water is taken from an external source such as a tap, hose, or special plumbing fixture and is regulated into the seal cavity by means of a needle valve and flow meter. Use of an anti-siphon check valve is required.

Figure 9 - Internal Flush

It is essential that an

anti-siphon check valve be installed between the pump and the city water supply to prevent any back flow from possibly contaminating the city water supply. Failure to do so could result in contamination of the water supply with consequential damages. Manufacturer assumes no responsibility for failure of user in not providing safeguards to city water systems.

Step 1: Locate appropriate city water supply and install anti-siphon check valve.

Step 2: Use appropriate pipe nipple to reduce piping to 1/8”.

Step 3: Install appropriate needle valve and flow meter.

Step 4: Connect piping to one of three available seal flush ports on pump.

Step 5: Adjust needle valve to achieve desired flow to seal cavity (recommended 1 to 3 GPH).

INTERNAL FLUSH

Similar to above but internal supply (See Figure 9 for typical installation). Typically recommended for high viscosity applications ensuring lubrication to the mechanical seal.

In an internal flush system, the fluid is taken from the discharge and regulated from 1 to 3 GPH (Gallon Per Hour) to the seal cavity by means of a flow meter and needle valve.

Step 1: Select a T pipe coupling that is consistent with discharge pipe size and material. Couple to discharge piping.

Step 2: From this coupling, attach a needle valve with appropriate nipple reducing to 1/8” pipe or tube. Install appropriate flow meter.

Step 3: Connect 1/8” pipe or tube to one of three available seal cavity flush ports.

Step 4: Adjust needle valve to desired flow into seal cavity

, (recommended

1 to 3 GPH).

For alternate flush

systems for hazardous fluid applications, hot liquid transfer those not addressed in this booklet, consult a qualified fluid handling specialist for assistance in specifying and installing flush sys tems according to local, state and federal environmental laws.

GEAR SPEED REDUCER OPTIONS

A gear reducer can be directly mounted between a standard pump and motor combination. Gear speed reducers are available for applications with high specific gravity, or when viscosities are greater than 500 SSU, using a standard 1725 RPM motor (See Appendix 2). The pump relationship between volume (GPM), pressure (PSI), speed (RPM), viscosity, specific gravity and horsepower is shown on performance chart in Shurflo Motor Manual form L-4082.

13. Unit is ready for operation.

Maintenance

Make certain that the

power source is disconnected before attempting to service or disassemble any components!

If the power disconnect is out of sight, lock it in the open position and tag to prevent application of power.

CLEANING

Clean the suction line filter at regular intervals.

ELECTRIC MOTOR (IF SUPPLIED)

Properly selected and installed, electric motors are capable of operating for

ears with minimal maintenance.

y Periodically clean dirt accumulations from open-type motors, especially in and around vent openings, preferably by vacuuming (avoid imbedding dirt in windings). Oil and maintain as recommended by motor manufacturer.

GENERAL

Periodically check that electrical connections are tight. Pump should be drained if placed in an area that is subject to freezing temperatures.

REASSEMBLY

(Refer to Figure 12 for Reference Numbers and Figures 10 & 11 for detailed seal and shaft assemblies.)

1. Shaft/Seal Assembly

a. Install inside o-ring (Ref. No. 10)

into body (Ref. No. 4). Lubricate with water on bronze models and oil on cast iron models.

b. Refer to assembling components

on drive shaft (See Figure 10). When installing the seal on the shaft, wet with water and be cautious when sliding it into position. The spring retaining washer and spring are behind the seal with the carbon ceramic facing towards the keyed end of drive shaft.

c. There are two possible types of

seals. One style, the seal is one piece while the other style has a seal boot, spring and spring retainer. The seal seats can also be of two styles; one has a rubber boot and the other has an o-ring. Identify which type you have (See Figure 11). Press seal seat into the seal retainer (See Figures 10 & 11) using water as a lubricant. The white shiny ceramic face should be visible after pressing the seal to the seal retainer mended to use a cardboard wash er or wood dowel when pushing the seal seat into the seal seat retainer fingerprints on the carbon ceramic faces will cause the seal to leak. The seal seat is stationary in the pump, while the seal on the shaft rotates, providing for the sealing surface.

d. Slide the seal retainer onto

the drive shaft holding seal onto the shaft.

. Any scratches, dirt, or

. It is recom

e. Slide the drive shaft assembly

(Ref. Nos. 5,6,7,8 &19) into the

ear pump and secure with the

g internal retaining ring (Ref. No.

28). (Also see Figure 10.)

f. As a last step, install o-ring (Ref.

No. 20) over the drive splines of the drive shaft (Ref. No. 5).

2. Gear and Shaft Installation

a. Install external retainer ring (Ref.

No. 22) onto drive shaft assembly (Ref. No. 5). Replace the woodruff key (Ref. No. 24) into the drive shaft (Ref. No. 5) using soft jaw pliers, or protect the shaft with rubber while pressing the key in place. Be sure that the key is level and that the key and shaft are free of burrs and scratches.

b. The drive gear (Ref. No. 21) can

be dropped in place and must be free to float on the shaft. Do not force the drive gear onto the shaft. Install external retainer ring (Ref. No. 22) onto drive shaft assembly (Ref. No. 5).

c. The idler gear (Ref. No. 21) is

placed on the idler shaft (Ref. No.

23) over the woodruff key and secured by the two external retaining rings (Ref. No. 22).

d. Slide idler gear and shaft assem-

bly into pump body (Ref. No. 4), rotating gear to get gears to

mesh.

e. Ensure that the gasket surfaces

are clear of debris, and dry off surfaces.

Place new, clean and dry gasket on the pump body by sliding gasket over dowel pins. For bronze mod els, refer to Appendix 1, to identify the right thickness of gasket to use.

Any foreign or liquid

material on the gasket or the gasket surfaces will increase the space between the gears and the cover, and substantially reduce pump performance.

f. Slide cover over dowel pins. The

drive shaft assembly will require

light compression as cover is

s tightened. Replace and tighten cover screws. Alternate from top to bottom and side to side while tightening screws. Torque cover screws (See Appendix 1).

g. Reinstall pump to motor (See

Assembly on page 5).

3. All pumps must be primed before start-up and the seal chamber needs to be filled (See Figure 5).

Appendix 1 - Gear Pump Gasket Adjustment for Temperature (Bronze Models only)

Gear pump is factory assembled to

perate within a temperature range

o of 70° – 120° F (20° – 50° C). For temperatures outside this range,

lease see the table below for your

p series and port size pump.

NOTE: Always refer to the original owner’s manual repair and maintenance sections on pump disassembly and assembly for more detailed instructions.

NOTE: When pumping fluids of high

iscosity (>500 SSU), the required torque

v and HP can be reduced by adding a gasket for increased gear clearance.

Gasket Installation Instructions (refer to assembly diagram below):

1. Turn off power to pump, turn off inlet and outlet valves, and relieve pressure in lines.

2. Allow pump to cool.

3. Remove cover screws (1), cover (2) nd gasket (3). Be sure to mark

a proper orientation of cover and pump body.

4. Replace gaskets (3) per instructions

listed in table.

5. Replace cover (2) and cover screws

(1) according to orientation marked in step 3.

6. Tighten cover screws (1) in

sequence listed on diagram. Use torque specifications listed in table.
