WARNING: Please read completely before you install or operate your new pump! This is an external “out-of-pond” pump! It is NOT submersible! Do NOT allow this pump to become submerged! Never run dry!

We congratulate you on your choice of the EXP Self Priming Pump! It has been carefully designed using the advantages of today’s technology and carefully constructed to give you the dependability of yesterday. To insure proper performance, we urge you to carefully follow the instructions in this manual. If you have any questions, call your nearest distributor or EasyPro for assistance.

INSTALLATION

Please read carefully! When properly installed this pump will provide dependable trouble-free service.

1. Locate pump as near the source to be pumped as possible. A flooded suction situation is preferred. This pump is self-priming, however, there must be fluid in the pump for it to function properly. A check valve is recommended for non-flooded suction. (Figure 2)

2. Mount motor base to a secure, immobile foundation.

3. Use only plastic fittings on both the intake and discharge ports. Seal pipe connections with Teflon paste. These fittings should be self-supported and in neutral alignment with each port. (i.e. Fittings must not be forced into alignment which may cause premature line failure or damage to the pump volute.)

4. Never restrict the intake. Keep both input and discharge lines as free of elbows and valves as possible. Always use pipe of adequate diameter. This will reduce friction losses and maximize output.

5. This pump must not be run dry! We recommend a flooded suction installation. Please read carefully! When properly installed, the pump will provide dependable, trouble-free service.

6. Before starting pump, the priming pot must be filled with water.

WARNING: WARNING: ALWAYS SHUT OFF ELECTRICAL POWER BEFORE INSTALLATION AND / OR SERVICING THIS PUMP! ALL ELECTRICAL WIRING SHOULD MEET STATE AND LOCAL ORDINANCES. IMPROPER WIRING MAY NOT ONLY BE A SAFETY HAZARD BUT MAY PERMANENTLY DAMAGE THE MOTOR AND/OR PUMP!

ELECTRICAL HOOK-UP

1. Check that supply voltages match the motor’s requirements.

2. Check motor wiring and connect, according to instructions on motor, to match supply voltage.

3. Power cord should be protected by conduit or by cable and be of proper gauge. It should be no longer than necessary.

4. Power should be drawn directly from a box with circuit breaker protection or with a fused disconnect switch.

PUMP END ASSEMBLY

1. Clean and inspect all pump parts (0-ring, seal seats, motor shaft, etc.).

2. If replacing the seal, apply sealant in bracket bore hole and around seal case according to sealant instructions. We recommend using Gasgacinch®. Silicone sealant can also be used.

3. Press seal into bracket while taking care not to damage seal face.

4. Place slinger (rubber washer) over motor shaft and mount bracket to motor.

5. If replacing the seal, carefully lubricate the boot around ceramic piece and press it into the impeller hub making certain that the ceramic is in evenly — the sealing surface should be parallel with the impeller hub.

6. Apply clean water to the carbon-graphite and seal seat sealing surfaces. Do not use silicon lubricants or grease!

7. Mount bracket to motor face.

8. Thread impeller onto shaft and install o-ring and screw! If required, remove motor end-cap and use a screwdriver on the back of motor shaft to prevent shaft rotation while tightening. Replace motor end cap.

9. Place diffuser over impeller and tighten allen bolts used to hold diffuser in place. Note: Be sure diffuser is in an upright position. (The word “top” appears on the diffuser as an indicator).

10. Seat O-ring on diffuser. Assemble diffuser to bracket with two allen screws.

11. Seat O-ring in bracket slot and assemble casing to bracket.

12. Install drain plugs with its O-rings in casing drain holes.

DISASSEMBLY

1. Shut off power to motor before disconnecting any electrical wiring.

2. Close all necessary valves on inlet and discharge lines and drain the pump by removing both drain plugs. The water will drain faster if you loosen the lid.

3. Disassemble bracket-motor assembly from casing by removing the nuts and bolts. (The casing may be left inline)

4. Unscrew the two allen bolts and remove diffuser. Diffuser may need to be pried off with a fl athead screwdriver.

5. Remove screw and O-ring from front side of impeller. Screw is a left-handed thread and loosens in a clockwise direction.

6. Remove cap covering shaft at back of motor. Unscrew the impeller by twisting counter clockwise while holding the shaft with a large screwdriver to prevent shaft rotation.

7. Remove ceramic piece from impeller (if replacing the seal).

8. Detach bracket from motor.

9. Remove seal from bracket by pressing out from the back (if replacing the seal). Do not dig out from the front!

MAINTENANCE

Lubrication
Rotary Seal - Requires no lubrication after assembly.

*The pump must be drained before servicing or if stored below freezing temperatures. Periodic replacement of seals may be required due to normal carbon wear.

TROUBLE SHOOTING AID

Motor will not rotate

• 1. Check for proper electrical connections to motor.
• 2. Check main power box for tripped circuit breaker.

Motor hums or will not rotate

• 1. Check for proper electrical connections to motor and proper wire size according to local electrical codes.
• 2. Check for foreign material inside pump.
• 3. Remove volute and check for impeller rotation without excessive resistance and/or noise.
• 4. Remove pump and check shaft rotation for excessive bearing noise.
• 5. Check start switch and/or capacitor.

Pump operates with little or no flow

• 1. Check to insure that pump is primed.
• 2. Check for leaking seal.
• 3. Improper line voltage to motor or incorrect rotation.
• 4. Check for clogged inlet port and/or impeller.
• 5. Defective check or foot valve.
• 6. Check inlet lines for leakage, either fluid or air.
• 7. Verify rotation direction of impeller (see page 2).

Pump loses prime

• 1. Defective check or foot valve.
• 2. Inlet line air leakage.
• 3. Seal leaking.
• 4. Fluid supply low.

Motor or pump overheats

• 1. Check for proper line voltage and phase, also proper motor wiring.
• 2. Binding motor shaft or pump parts.
• 3. Inadequate ventilation.
• 4. Fluid being pumped should not exceed 194°F (90°C) for extended periods
