SHURflo 316 Stainless Steel 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, external rotary gear pumps operate bi-directionally (reversible) and provide a nearly pulseless flow for a wide range of industrial, marine, agricultural, and commercial chemical-duty applications. Mounted directly to NEMA frame AC Totally-Enclosed Fan-Cooled (TEFC) motors using an easy-installation package, or as pump heads only for custom installations. Single-phase motors are thermally overload protected; 3-phase motors are not. Ryton PPS (Polyphenylene Sulfide) spur gears provide quiet operation and chemical compatibility with no metal-to-metal contact. Pumps can operate in a temperature range of 32° to 280° F.

Quality features include a keyed 316 stainless steel shaft supported by a ball bearing and carbon graphite bushings. Wet-end parts are constructed of 316 stainless steel, Ryton PPS, graphite, graphoil, carbon, ceramic, and Viton or Teflon

Uses: For use with non-particulate and non-abrasive fluids compatible with pump wet-end construction component materials.

• 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.

• Temperature ranges from 32° to 280° F.

• Large female NPT ports allow use with viscous fluids.

• Pumps are close-coupled with electric motors to handle up to 500 SSU 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.)

®

• Viton or Teflon external flush to handle viscosities beyond 2000 SSU.

• Pumps can operate bi-directionally (reversible).

REPAIR SEALS AND OPTIONS – Standard seals are Viton or Teflon located in the repair parts list pages in the owner’s manual. When switching between standard and optional mechanical seals, be sure to order the matching o-rings in the same material. These can be found in the repair parts list pages of 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 applications.

If a pump head needs to be coupled to an electric motor, then the following procedure should be followed. (See Figures 3 and 4.) First, install one of the two coupling halves and key on the pump shaft and tighten the set screw. The shaft end should be even or slightly recessed from the coupling half (approximately 1/8”). The other coupling half must be installed on the motor shaft. To do this, it should be placed on the shaft with the key, with the shaft recessed approximately 1/2”. The set screw is not yet tight-

ened. It is necessary to establish a gap between the coupling halves of approximately .02” to .05” (See Figure

4). A thin piece of cardboard or a piece of paper folded up will work fine to set this gap. The pump is placed into position on the motor and the position of the motor coupling half is established using the piece of thin cardboard or other gauge material. The motor coupling half is tightened. The pump is removed, the coupling spider (rubber piece) is placed into position, and the pump bolted to the motor using the four bolts.

Installation

IMPORTANT: 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 (See Figure 1 for proper rotation).

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 affect a prime.

6. If solid contaminates are suspected in a liquid, place a filter in the suction line.

7. Be certain all suction piping connections are airtight.

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

DISCHARGE

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 overpressure 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 valve 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 supplied 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

Remove plug and fill seal chamber

with fluid and reinstall plug

Figure 5 - Prime Plug

to be filled (See Figure 5). Never operate a pump unless it is secured to a solid foundation and all safety shields are installed.

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.

3. When pumping a more viscous

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

Torque.

4. Recheck motor and pump rotation. Pump rotation is by-directional (See Figure 1).

PRESSURE RELIEF VALVE

5. Standard models do not include a pressure relief valve. If discharge is going to be shut off, an external pressure relief valve should be installed.

GEAR PUMP GASKET ADJUSTMENT FOR TEMPERATURE (See Appendix 1)

6. For operation in fluid temperatures above 120° F, stainless steel pump models must have the gasket thickness adjusted. 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

7. These stainless steel 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 clearances between the gear teeth and the stainless steel 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 6 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.

Operation (Continued)

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 7 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 (Gallons 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, and those not addressed in this booklet, consult a qualified fluid handling specialist for assistance in specifying and installing flush systems 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.

8. 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

Properly selected and installed, electric motors are capable of operating for years with minimal maintenance. 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

Check the pump to motor shaft coupler alignment at regular intervals.

Periodically check that electrical connections are tight. Pump should be drained if placed in an area that is subject to freezing temperatures and should not be operated until temperature permits.

To store the pump, place a small quan-

tity of light oil or some other storage preservative compatible with your application in the pump and rotate the shaft very slowly to work the oil throughout the gears and the body.

REASSEMBLY

(Refer to Figure 13 for Reference Numbers and Figures 3, 8, 9, 10, 11 & 12 for detailed seal and shaft assemblies.)

1. Shaft/Seal Assembly

a. Install inside o-ring (Ref. No. 20)

into body (Ref. No. 11). Lubricate with water.

b. There are two possible standard

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 10). (For the Teflon seal, see the following note and Figure 12.)

c. Refer to assembling components

on drive shaft (See Figure 9). 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 (See Figure 9).

d. Press seal seat into the seal

retainer (See Figure 11) using water as a lubricant. The white shiny ceramic face should be visible after pressing the seal into the seal retainer. It is recommended to use a cardboard washer or wood dowel when pushing the seal seat into the seal seat retainer. Any scratches, dirt, or 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.

NOTE: When installing the seat for the Teflon seal, an anti-rotation pin must be installed into the seat retainer. The anti-rotation pin (Ref. No. 25) is a small spring pin which must be installed into the seat retainer in the small hole. About 1/8” to 3/16” of the pin should be exposed inside of the seat retainer (Figure 11). The seal seat is then installed into the seat retainer.
