Description

SHURflo pedestal non-metallic pumps produce high flow rates under moderate head conditions. Designed for continuous medium pressure circulation and transfer of nonflammable liquids, water circulation, booster

service, irrigation, spraying systems, jockey pump service, aggressive liquid applications, and other general-purpose pumping compatible with pump component materials where no suction lift is required. Water seal flush port is provided for the decontamination of chemicals on the seal and seat elastomers.

• Capacities to 110 GPM, heads to 95 ft.

• 1/3 to 3 HP AC requirement range.

• Discharge can be rotated in 90-degree intervals.

• All pumps have 1

• Standard pump models (at 3450 RPM) will handle specific gravities to 1.1 (at 100 SSU or less). For specific gravities to 1.4 (at 100 SSU or less), increase motor HP by one size but not to exceed standard 3 HP motor at 3450 RPM or 65 in.-lbs. of torque maximum. Higher specific gravity fluids are not recommended.

• Standard pump models (at 3450 RPM) will handle viscosity to 100 SSU (at 1.1 specific gravity or less) and up to 200 SSU (specific gravity of 1.0 or less). For viscosity up to 400 SSU (specific gravity of 1.0 or less), increase motor HP by one size but not to exceed standard 3 HP motor at 3450 RPM or 65 in.-lbs. of torque. For fluids with a viscosity greater than 400 SSU, pump speed must be reduced below 3450 RPM.

• Maximum operating speed is 3600 rpm.

• Pedestal-mount models feature a 5/8" diameter; 316 stainless steel solid shaft; a corrosion-resistant coated cast iron bearing

housing and sealed ball bearings. They may be either long coupled or pulley driven with any base-mounted motor such as ODP, TEFC or wash-down motors.

CLOSE COUPLED – Non-metallic pumps are also available that feature NEMA 56J frame motors with base. NORYL SERIES – This series is designed for industrial chemical application. The pumps are made of Noryl, which is non-metallic

and chemical-resistant to most acids, alkalis, and inorganic solvents. This material is stiffer under pressure and temperature than the Polypropylene Series. Noryl models handle inlet booster pressures to 30 PSI and maximum temperatures up to 180° F. These pumps are equipped with a unique chemical-resistant, carbon and ceramic mechanical seal with Viton elastomer having the stainless steel components sealed in Noryl allowing for a complete non-metallic Noryl wet end. This unique seal guarantees reliability through simplicity and balance of design. Even the pedestal drive shaft is protected by the seal design.

POLYPROPYLENE SERIES – This series is designed for light industrial or commercial water-based applications. The pumps are made of non-metallic, glass-filled polypropylene construction offering chemical resistance to most acids, alkalis, and inorganic solvents as does the Noryl Series. The difference is these pumps are equipped with a carbon ceramic mechanical seal with Buna-N elastomers with the stainless steel components that are not sealed, but still protect the pedestal shaft from chemical exposure. The polypropylene series cannot handle added inlet booster pressures and is rated for a maximum temperature of

. However

140 REPAIR SEALS AND OPTIONS – Standard and upgraded seals are available for both the Noryl and Polypropylene pumps.

If abrasive or small, particulated fluids are being pumped, upgrading to either the encased Noryl or polypropylene silicon carbide mechanical seal with Viton elastomers is recommended. Standard and upgraded seals can be located on the repair parts list pages in this manual.

PUMP HEADS AND PEDESTAL MOUNT BASE – Complete pump heads and pedestal base can be ordered. Pump head and pedestal base model numbers are called out in the repair parts list pages in this manual.

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

For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction.

Make certain

that the unit is disconnected from the power source before attempting to service or remove any components! Do not exceed 3600

rpm operating speed.

Drive Source Installation for the Pedestal-Mount Pump

his manual covers the installation of

T the basic drive configuration for the pedestal polypropylene and noryl centrifugal pumps. Consult the manufacturer of motor or engine for additional information. Read all instructions before attempting to install or operate the pump. The unit should run clockwise as viewed facing the shaft end. Counterclockwise rotation can result in damage to the pump motor, property damage and/or personal injury.

Safety shields are

required and must be mounted and kept in place while power is supplied to pump drive.

BELT/PULLEY DRIVE INSTALLATION

1. For pulley-driven pumps, a single 1/2" [12.7 mm] (A or 4L section) “V” belt is satisfactory for drive sizes and speed up to 1 HP, 3450 RPM. For larger sizes, double “V” belts are recommended.

2. Mount pulleys as close to the ump and motor engine shaft

p bearings as possible. Check the

lignment with a straight edge as

a shown in Figure 1. Make sure that

he belt has proper tension. (Too

t much tension will cause bearing wear; too little will cause slippage). See Figure 2. Check with belt and pulley sources for specific recommendation. A safety shield (belt guard) must be installed over the motor/pump pulleys and belts.

3. To figure proper diameter of pump pulley, multiply motor/engine RPM by the diameter of the motor/engine pulley and divide that figure by the desired pump speed.

Pump Pulley = Size

Motor RPM x Motor Pulley Size

Desired Pump Speed

4. A safety shield (belt shield) must be installed over the pump and motor shafts, pulleys and belt.

NOTE: Refer to the pump performance charts to determine the desired speed to obtain the desired maximum flow.

Direct Drive - Flexible Coupling

For direct driving of pedestal centrifugal pumps with flexible couplings, make sure that the speed (RPM) of the gas engine or electric motor is within the maximum rated RPM of your pump. Make sure that shaft rotation is correct between the pump and the motor or gas engine (see Figure 3).

1. Mount the motor or engine into position on the base.

2. Line up the pump shaft with the straight edge as shown in Figure 4 to assure they are aligned. Shim the pump if necessary to match the shaft height of the engine or motor. The shaft ends should not touch.

3. Mark the exact position of the pump on the base. Remove and install the coupling halves on both shafts. Place the coupling center disc into one of the coupling halves.

4. Re-position the pump, sliding the coupling halves together.

NOTE: No end thrust should be applied to the pump when the coupling is connected.

5. Tighten the pump mounting and then the set screws on each coupling.

6. A safety shield (coupling guard) must be installed over the pump and motor shafts and coupling.

Pump Installation

Do not run the pump

dry! Check pump rotation before operating. Pump rotation should be clockwise as seen from shaft end. Reverse rotation can result in severe pump damage.

1. Position the pump as close as possible to the source being pumped. A flooded suction situation is required. The pump is NOT selfpriming, therefore, if the fluid

is below the pump, a foot

level valve must be installed and the pump primed prior to start-up.

Form L-4074 (12/09)

2. Mount the pedestal base to a secure, immobile foundation.

3. Use only composite fittings on both the intake and discharge ports. Seal the pipe connections with Teflon™ tape. These fittings should be self-supported and in neutral alignment with each port. Fittings must not be forced into alignment because it may cause premature line failure or damage to the pump housing volute.

4. Never choke the intake. Keep both input and discharge lines as free of elbows and valves as much as pos

sible. Always use an adequate diameter pipe. This will reduce friction losses and maximize output.

5. For positive pump start-up upon intial installation or after pump has been maintained or fluid drained from pump, fill pump with water or liquid compatible with pumped material. This is accom plished by installing a “T” fitting on the discharge with the fill portion of the fitting facing up.

Maintenance

Make certain

that the unit is disconnected from the power source before attempting to service or remove any components!

REMOVAL OF OLD SEAL ASSEMBLY

Should the mechanical seal (Ref. No. 5) require repair, proceed as follows and refer to Figures No. 5 - 7.

IMPORTANT: Always replace both the seal seat and seal as an assembly to ensure proper mating of components!

1. Remove bolts (Ref. No. 8) connecting the pump housing casing (Ref. No. 2) to the body adapter (Ref. No. 1).

2. Remove the pump housing casing (Ref. No. 2).

Care should be taken

not to pinch or ”shave” the O-ring gasket (Ref. No. 6) between the body adapter and the housing casing.

3. Remove the impeller (Ref. No. 4) from the shaft by unscrewing it counterclockwise as viewed from the pedestal pump face.

NOTE: Pump shaft must be held in place to remove impeller. Impeller (Ref. No. 4) unscrews CCW when looking at the front of the pump.

4. The ceramic seat is located on the back side of the impeller (part of Ref. No. 5). Pry the seat out by using a screwdriver in the inside hole (see Figure 5). Be careful not to damage or scratch the inside surfaces of the bore holding the seat. Such scratches can cause leaks. Replace the impeller if such damage occurs.

5. Remove the body adapter (Ref. No. ) from the pedestal by removing

1 the adapter bolts.

. Use a wooden dowel to push out

the mechanical seal (part of Ref. No. 5) from the body adapter (Ref.

o. 1). (See Figure 5.) Do not dig

N the seal out from the front.

INSTALLATION OF NEW SEAL ASSEMBLY

The precision

carbon/ceramic faces on the mechanical seal are easily damaged. Handle your repair seal carefully. Do not touch the carbon/ceramic seal faces.

IMPORTANT: Be sure that shaft shoulder does not damage carbon face.

1. Thoroughly clean all surfaces of the seal cavity in body adapter (Ref. No. 1).

2. Replace the o-ring inside the cavity (Ref. No. 11). Using seal installation tool (see Figure 6), press in new mechanical seal being careful not to scratch the polished carbon face.

3. Wet the rubber portion of the new seal seat (part of Ref. No. 5) with a light coating of soapy water. While wearing clean gloves or using a clean light rag, press seal seat squarely into impeller recess. Use the cardboard washer (usually supplied with new seal) to place over the polished ceramic surface and use a piece of pipe or dowel rod to press in firmly but gently (see Figure

5). Avoid scratching the ceramic face, usually white.

4. Dispose of cardboard washer. Check gain to see that ceramic surface is

a free of dirt and all other foreign particles and that it has not been

cratched or damaged.

5. Install the body adapter (Ref.

o. 1) to the pedestal using bolts.

N Be careful not to damage the seal when sliding over the shaft.

6. While preventing the shaft from

turning, screw impeller (Ref. No. 4) onto shaft and tighten (see Figure 5).

NOTE: A short “run-in” period may be necessary to provide completely leakproof seal operation.

This completes the seal installation.

7. Check if shaft turns freely by spin-

ning impeller. If rubbing or binding is found, remove impeller.

8. Place o-ring (Ref. No. 6) into groove

on back side of housing. It may be necessary to temporarily hold the o-ring in the groove with grease.

Seal assembly will

produce minor drag when spinning shaft, but rubbing anywhere else must be eliminated! Otherwise, damage to pump and/or motor may occur.

Figure 5 - Seal Install

Water-Flushed Seals

1. Water-flushed seals are recommended for abrasive solutions, high temperature service, or when pumps may be run dry or against deadhead conditions.

2. When conditions cause the pumped liquid to form crystals, or if the pump remains idle for a period of time without adequate flushing, a water-flush seal system is advised.

3. The water flush will provide decontamination of chemicals on elastomers and seal and seat faces, while providing lubrication required for start-up. Two (2) methods of water flush can be used:

a. Direct Plumbing to City Water

This provides the best possible approach to flushing the seal and seat faces. Caution must be taken to conform to local city ordinances that may require backflow preven ters. These are a series of check valves required to prevent contamination of city water if the water supply is shut off. Also be aware of the addition of water into the chemicals pumped where some imbalance may be created, altering the chemical’s formulation and aggressiveness.

b. The flush port is provided on the

side of the pump below the discharge.

c. Recirculation of Solution Pumped

This system takes a bleed off the pump discharge and recirculates the solution in the seal chamber. Although not nearly as effective as the direct water flush, it will provide cooling to the seal and seat faces under operation. This system is not ef crystalization occurs or for pumps in idle conditions.

fective where

Figure 6 - Seal Install Tool

For internal recirculation to seal, drill the recess plug on the pump body located at 3 o’clock with a 1/8” drill.

Hazardous substance alert!

4. Always drain and flush the pump before servicing, disassembling for any reason or returning the unit for repair.

5. Never store pumps containing hazardous chemicals.

6. Before returning the pump for service/repair, drain out all liquids and flush the unit with a neutralizing liquid. Then, drain the pump. Attach a tag or include a written notice certifying that this has been done.
