Motor or pump overheats.2018-05-30T17:32:09+00:00

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 of time.

Motor Hums Or Will Not Rotate At Correct Speed2018-05-30T17:31:25+00:00

1. Check for proper electrical connections to the motor and proper cord size and length.
2. Check for foreign material inside the pump.
3. Remove the bracket and check for impeller rotation without excessive resistance.
4. Remove pump and check shaft rotation for excessive bearing noise.
5. Have authorized serviceman check start switch and/or condenser.

Motor will not rotate.2018-05-30T17:30:42+00:00

1. Check for proper electrical connections to motor.
2. Check main power box for blown fuse, etc.
3. Check thermal overload on motor.

Pump operates with little to no flow.2018-05-30T17:29:45+00:00

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.

My pump keeps loosing its prime. 2018-05-30T17:29:09+00:00

A: Check for:

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

We have a new system and just installed the pump and it’s making a noisy sound, sort of like its pumping sand.2018-05-30T18:15:15+00:00

A: If the motor connections are properly set, then you need to check the actual voltage supplied at the motor. It is best to do this with the motor, and any other lights or equipment that share that circuit, running. Using a voltmeter, check the voltage across Line 1 and Line 2 leads. It should be within 5% of the nominal 115 or 230V. It the voltage is low, correct the problem before trying to operate the pump.

With the pump running, slowly close down your valve on the discharge side of the pump. If the noise goes away, then you were hearing cavitation. Cavitation is caused when the pump isn’t getting water re-supplied quickly enough. To remedy this, you need to

1. Reduce the output by partially closing a valve on the discharge, until you reach a point where the cavitation stops.
2. Increase the diameter of pipe on the suction of the pump.
3. Shorten the length of the pipe on the suction of the pump.
4. Reduce the numbers of elbows on the suction of the pump.
5. Lower the elevation of the pump.
Any one or combination of the above changes will help eliminate cavitation.

I just installed a new unit and when I turn it on, the motor makes a funny sound and doesn’t come up to speed properly.2018-05-30T18:15:42+00:00

A: Check to make sure that the supply voltage matches the voltage the motor is set for. In other words, if your motor is wired according to 230 Volt connections, then your supply line must also be 230Volts.
