General Safety

WARNING
Hazardous pressure!
Do not run pump against closed discharge.
Release all pressure on system before working on any component.
Pump is designed as a lawn sprinkler only. To avoid heat built-up, over pressure hazard and possible injury, do not use in a pressure tank (domestic water) system.
Do not use as a booster pump; pressurized suction may cause pump body to explode.
Do not allow pump or piping system to freeze. Freezing can damage pump and pipe, may lead to injury from equipment failure and will void warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on pumps.
Keep work area clean, uncluttered and properly lighted; store properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.

Before You Install Your Pump

Figure 1 – No Dirt or Scale in Suction Pipe	Figure 2 – Foot Valve Must Work Freely
Figure 3 – No Air Pockets in Suction Pipe	Figure 4 – Suction Pipe Must Not Leak

NOTICE: Well must not be more than 20’ depth to water.

1. Long runs and many fittings increase friction and reduce flow. Locate pump as close to well as possible: use as few elbows and fittings as possible.
2. Be sure well is clear of sand. Sand will plug the pump and void the warranty.
3. Protect pump and all piping from freezing.
   Freezing will split pipe, damage pump and void the warranty. Check locally for frost protection requirements (usually pipe must be 12” below frost line and pump must be insulated).
4. Be sure all pipes and foot valve are clean and in good shape.
5. No air pockets in suction pipe.
6. No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal pipe joints.
7. Unions installed near pump and well will aid in servicing. Leave room to use wrenches.
8. WARNING Pump body may explode if used as a booster pump. DO NOT use in a booster application.

Well Pipe Installation

Figure 5 – Cased/Dug Well Installation	Figure 6 – Driven Point Installation	Figure 7 – Multiple Discharge

NOTICE: Use the installation method below which matches your well type.
CASED WELL INSTALLATION

1. Inspect foot valve to be sure it works freely. Inspect strainer to be sure it is clean.
2. Connect foot valve and strainer to the first length of suction pipe and lower pipe into well. Add sections of pipe as needed, using PTFE pipe thread sealant tape on male threads. Be sure that all suction pipe is leakproof or pump will lose prime and fail to pump. Install foot valve 10 to 20 feet below the lowest level to which water will drop while pump is operating (pumping water level). Your well driller can furnish this in formation.
3. To prevent sand and sediment from entering the pumping system, the foot valve/strainer should be at least 5 feet above the bottom of the well.
4. When the proper depth is reached, install a sanitary well seal over the pipe and in the well casing.
   Tighten the bolts to seal the casing.
5. When using a foot valve, a priming tee and plug as shown in Figure 5 are recommended.

DUG WELL INSTALLATION
Same as cased well installation.
DRIVEN POINT INSTALLATION

1. Connect the suction pipe to the drive point as illustrated in Figure 6. Keep horizontal pipe run as short as possible. Use PTFE pipe thread sealant tape on male pipe threads. Multiple well points may be necessary to provide sufficient water to pump.
2. Install a check valve in horizontal pipe. Flow arrow on check valve must point toward pump.

HORIZONTAL PIPING FROM WELL TO PUMP

1. Never install a suction pipe that is smaller than the suction port of the pump.
2. To aid priming on well point installations, install a line check valve as shown in Figure 6. Be sure check valve flow arrow points toward pump.

DISCHARGE PIPE SIZES

1. If increasing discharge pipe size, install reducer in pump discharge port. Do not increase pipe size by stages.
2. When the pump is set away from the points of water use, the discharge pipe size should be increased to reduce pressure losses caused by friction.
   • Up to 100’ run: Same size as pump discharge port.
   • 100’ to 300’ run: Increase one pipe size.
   • 300’ to 600’ run: Increase two pipe sizes.

LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. It is de signed to deliver plenty of water at full sprinkler pressure. It can pump from a pond, cistern or well points.
Pump discharge can be divided to supply two (2) or more sprinkler systems. A suggested multiple discharge to service is shown in Figure 7.
Do not use in a pressure tank or booster pump application.

Pump/Piping Installation

	Drawings are for PDSS, PD, and PD2 Series pumps. PD2 Series is shown.
Figure 8 – Bolt Pump Down	Figure 9 – Independently Support All Piping Attached to Pump
Figure 10 – Use PTFE pipe thread sealant tape on pipe joints and connections to pump.	Figure 11 – Don’t overtighten.

PUMP INSTALLATION
NOTICE: Use only PTFE pipe thread sealant tape for making all threaded connections to the pump itself. Do not use pipe joint compounds on plastic pumps: they can react with the plastic in the pump components. Make sure that all pipe joints in the suction pipe are air tight as well as water tight. If the suction pipe can suck air, the pump will not be able to pull water from the well.

1. Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 1-1/2 to two layers of PTFE pipe thread sealant tape clockwise (as you face end of pipe) on all male threads being attached to pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not overtighten.

NOTICE: Install pump as close to well head as possible. Long piping runs and many fittings create friction and reduce flow.
NOTICE: For long horizontal pipe runs, install a priming tee between check valve and well head as shown in Figure 6. For driven point installations, install a check valve as shown in Figure 6. Be sure check valve flow arrow points toward pump.
Use schedule 80 or iron pipe. See “Well Pipe In stallation” for more information.

Figure 12: Changing the Voltage Setting	Figure 13: Motor Set for 115 Volt Operation

WARNING Hazardous voltage. Can shock, burn, or cause death. Disconnect power to motor before working on pump or motor. Ground motor before connecting to power supply.
WIRING
Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections.
Supply voltage must be within ±10% of nameplate voltage. Incorrect voltage can cause fire or damage motor and voids warranty. If in doubt consult a licensed electrician.
Use wire size specified in Wiring Chart (Page 7). If possible, connect pump to a separate branch circuit with no other appliances on it.
Wire motor according to diagram on motor nameplate. If nameplate diagram differs from diagrams above, follow nameplate diagram.

1. Install, ground, wire and maintain this pump in accordance with electrical code requirements.
   Consult your local building inspector for information about codes.
2. Provide a correctly fused disconnect switch for protection while working on motor. Consult local or national electrical codes for switch requirements.
3. Disconnect power before servicing motor or pump.
   If the disconnect switch is out of sight of pump, lock it open and tag it to prevent unexpected power application.
4. Ground the pump permanently using a wire of the same size as that specified in wiring chart (Page 7).
   Make ground connection to green grounding terminal under motor canopy marked GRD. or
   
5. Connect ground wire to a grounded lead in the service panel or to a metal underground water pipe or well casing at least 10 feet long. Do not connect to plastic pipe or insulated fittings.
6. Protect current carrying and grounding conductors from cuts, grease, heat, oil, and chemicals.
7. Connect current carrying conductors to terminals L1 and L2 under motor canopy. When replacing motor, check wiring diagram on motor nameplate against Figures 12-13. If the motor wiring diagram does not match either diagram in Figures 12-13, follow the dia gram on the motor.
   IMPORTANT: 115/230 Volt single phase models are shipped from factory with motor wired for 230 volts. If power supply is 115 volts, remove motor canopy and reconnect motor as shown in Figures 12-13. Do not try to run motor as received on 115 volt current.
8. Motor has automatic internal thermal overload protection. If motor has stopped for unknown reasons, thermal overload may restart it unexpectedly, which could cause  injury or property damage. Disconnect power before servicing motor.
9. If this procedure or the wiring diagrams are confusing, consult a licensed electrician.

(*) Dual element or Fusetron time delay fuses recommended for all motor circuits.

Operation

PRIMING THE PUMP
NOTICE: ‘Priming’ refers to the pump expelling all air in the system and beginning to move water from its source out into the system. It does not refer only to pouring water into the pump (although pouring water in is usually the first step).
NOTICE: NEVER run pump dry. Running pump without water in it will damage seals and can melt impeller and diffuser. To prevent damage, fill pump with water before starting.

1. Remove priming plug (Figure 14).
2. Make sure suction and discharge valves and any hoses on discharge side of pump are open.
3. Fill pump and suction pipe with water.
4. Replace priming plug, using PTFE pipe thread sealant tape on thread; tighten plug.
   NOTICE: If a priming tee and plug have been provided for a long horizontal run, be sure to fill suction pipe through this tee and replace plug.
   (Don’t forget to seal the plug with PTFE tape.)
5. Start pump: water should be produced in 10 minutes or less, the time depending on depth to water (not more than 20’) and length of horizontal run (10’ of horizontal suction pipe = 1’ of vertical lift due to friction losses in the pipe).

If no water is produced within 10 minutes, stop pump, release all pressure, remove priming plug, refill and try again.
WARNING Hazardous pressure and risk of explosion and scalding. If pump is run continu­ ously at no flow (that is, with discharge shut off or without priming), water may boil in pump and piping system. Under steam pressure, pipes may rupture, blow off of fittings or blow out of pump ports and scald anyone near.
To prevent explosion, do the following:
A. Be sure discharge (valve, pistol grip hose nozzle, etc.) is open whenever pump is running.
B. If pump fails to produce water when attempting to prime, release all pressure, drain pump and refill with cold water after every two attempts.
C. When priming, monitor pump and piping temperature. If pump or piping begin to feel warm to the touch, shut off pump and allow system to cool off. Release all pressure in system and refill pump and piping with cold water.

Maintenance

MAINTENANCE
Pump and piping need not be disconnected to repair or replace motor or seal (see Figure 19). If motor is replaced, replace the shaft seal. Keep one on hand for future use.
Be sure to prime pump before starting.
NOTICE: Check motor label for lubrication instructions.
The mechanical shaft seal in the pump is water lubricated and self-adjusting.
NOTICE: Drain pump when disconnecting from service or when it might freeze.
PUMP DISASSEMBLY

1. Disconnect power to motor.
   NOTICE: Mark wires for correct assembly.
2. Remove clamp (see Figure 19).
3. Remove pump base mounting bolts. Motor assembly and back half of pump can now be pulled away from pump front half (Figure 19). CAREFULLY remove O-ring.

CLEANING/REPLACING IMPELLER
NOTICE: First, follow instructions under “Pump Disassembly”.

1. Remove four screws fastening diffuser to seal plate; remove diffuser (see Figure 20). Exposed impeller can now be cleaned.
2. If impeller must be replaced, loosen two machine screws and remove motor canopy (see Figure 21).
3. WARNING Capacitor voltage may be hazardous. To discharge capacitor, hold insulated handle screwdriver BY THE HANDLE and short capacitor terminals together (see Figure 21). Do not touch metal screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.
4. Unscrew capacitor clamp and remove capacitor. Do not disconnect capacitor wires to motor.
5. Slide 7/16” open end wrench in behind spring loaded switch on motor end of shaft; hold motor shaft with wrench on shaft flats and unscrew impeller by turning counterclockwise when looking into eye of impeller.
6. To reinstall, reverse steps 1 through 5.
7. See directions under “Pump Reassembly,” Page 11.

REMOVING OLD SEAL

1. Follow instructions under “Pump Disassembly”.
2. Follow steps 2 through 5 under “Cleaning/Replacing Impeller”.
3. Unscrew four nuts holding pump back half to motor. Remove rotating half of seal by placing two screwdrivers under back half of pump body and carefully prying up (Figure 22). Back half of pump body will slide off shaft, bringing seal with it.
   NOTICE: Be sure you do not scratch or mar shaft; if shaft is marred, it must be dressed smooth with fine emery or crocus cloth before installing new seal.
   DO NOT reduce shaft diameter!
4. Place pump body half face down on flat surface and tap out stationary half of seal (see Figure 23).

INSTALLING NEW SEAL

1. Clean seal cavity in seal plate.
2. Wet outer edge of Rubber Cup on ceramic seat with liquid soap. Be sparing!
3. Put clean cardboard washer on seal face. With thumb pressure, press ceramic seal half firmly and squarely into seal cavity (See Figure 24). Polished face of ceramic seat is up. If seal will not seat correctly, remove, placing seal face up on bench.
   Reclean cavity. Seal should now seat correctly.
4. If seal does not seat correctly after recleaning cavity, place a cardboard washer over polished seal face and carefully press into place using a piece of standard 3/4” pipe as a press.
   NOTICE: Be sure you do not scratch seal face.
5. Dispose of cardboard washer and recheck seal face to be sure it is free of dirt, foreign particles, scratches and grease.
6. Inspect shaft to be sure it is free of nicks and scratches.
7. Reassemble pump body half to motor flange. BE SURE it is right side up.
8. Apply liquid soap sparingly (one drop is sufficient) to inside diameter of rotating seal member.
9. Slide rotating seal member (carbon face first) onto shaft until rubber drive ring hits shaft shoulder.
   NOTICE: Be sure not to nick or scratch carbon face of seal when passing it over threaded shaft end or shaft shoulder. The carbon surface must remain clean or short seal life will result.
10. Hold motor shaft with 7/16” open end wrench on shaft flats and screw impeller onto shaft. Be sure you do not touch capacitor terminals with body or any metal object. Tightening impeller will automatically locate seal in correct position.
11. Remount diffuser on pump body half with five screws.
12. Follow instructions under “Pump Reassembly”.

PUMP REASSEMBLY

1. Clean O-ring and O-ring groove.
2. Put O-ring in groove on face of flange; put pump halves together (see Figure 27).
3. BE SURE inside of clamp is clean. Place clamp on pump halves; snug up. Alternately tighten screw and tap clamp with mallet to seat O-ring (see Figure 28).
4. Replace base mounting bolts.
5. Replace pressure switch tubing and motor wiring; close draincock.
6. Prime pump according to instructions. See “Operation.”
