Dual Pre-Filter
1. Problem:The Feed Water Pressure into the Pre-filter is higher than normal, and the Feed Water Pressure
into the High Pressure Pump is lower than normal.
a. Description: The pressure differential readings across the Pre-filter indicate that the elements are filled with
debris blocking the feed water.
b. Solution: Replace the Prefilter Elements.
Commercial Pre-Filter
1. Problem: The Feed Water Pressure into the Prefilter is higher than normal, and the Feed Water Pressure
into the High Pressure Pump is lower than normal.
a. Description: The pressure differential readings across the Pre-filter indicate that the element is filled with
debris blocking the feed water.
b. Solution: Replace the Pre-filter Element.
Oil and Water Separator
1. Problem: The Feed Water Pressure into the Oil/Water Separator is higher than normal, and the Feed
Water Pressure into the High Pressure Pump is lower than normal.
a. Description: The pressure differential readings across the Oil/Water Separator indicate that the element is
filled with debris blocking the feed water.
b. Solution: Replace the Oil/Water Separator Element.
Std HP Pump Assembly
Prior to assuming that the High Pressure Pump’s Electric Motor has failed, perform a function test.
1. Problems: The Single Phase (115 or 230 VAC) Electric Motor “hums,” pulls starting current (locked
rotor) amperage, does not rotate, and trips the supply power circuit breaker when attempting to operate
the System.
a. Description: The Single Phase Electric Motor is a capacitor start motor. If the motor was started with low
voltage, a drop in voltage during starting, and if this was repeated several times in rapid concession the
capacitor will short out. Without the aid of a working capacitor the motor will “hum”, pull starting current
(locked rotor) amperage, not rotate, and trip the supply power circuit breaker when attempting to operate
the System. Low voltage will also cause the same symptom. Low voltage is caused by an undersized power
supply or generator, undersized power lead wires to the System or motor, loose power wire, or connection
at the motor or within the power supply line, and “burnt” contacts on the motor starter relay (contactor).
b. Solutions:
a. Check wiring size and connections to, from, and in between the Power Supply and the electric motor.
Correct wire size or any loose wires.
b. Check the capacitor on the motor, and replace it if it has shorted out.
c. Measure voltage at the motor during attempt to start it. If voltage drops more than 10% locate and correct
the reason.
d. Check the motor starter relay (contactor) for “burnt” contacts.
2. Problems: The Three Phase (230/380/460 VAC) Electric Motor “hums,” pulls starting current (locked
rotor) amperage, does not rotate, and trips the supply power circuit breaker when attempting to operate
the System.
