Operation Of Engine Driven Units; Starting; Rotation - Pioneer PB Series Operation & Maintenance Manual

Do not attempt to operate the pump unless all connecting piping, fill plug and other fittings are
securely installed, failure to do so, could cause liquid pumped to be forced out under pressure
causing injury to personnel.
WARNING!!!
Never run the pump with the discharge valve closed for extended periods of time. Never use
the suction valve to throttle the flow. Check all suction and discharge piping for leaks.
If a suction strainer is installed, check the pressure drop across the strainer. If the differential in
pressure exceeds five (5) PSI have the strainer cleaned.

OPERATION OF ENGINE DRIVEN UNITS

Review pre-start instructions in the beginning of the Operation section.
Before Starting,
Check the fuel level and oil levels in the engine.
CAUTION!!!
Make sure the pump is level. Lower jack stands and chock the wheels. Use caution when
positioning the skid-mounted unit to prevent damage to the fuel tank. Consult the engine
operations manual before attempting to start the unit.
WARNING!!!
Do not operate the pump without guards in place over the rotating parts. Exposed rotating parts
can catch clothing, fingers or tools, causing severe injury to personnel.

STARTING

Consult the operations manual furnished with the power source.

Rotation

The correct direction of pump rotation is counter-clockwise when standing on the suction side
of the pump and facing the impeller. The pump could be damaged and performance adversely
affected by incorrect rotation. If pump performance is not within the specified limits, verify
rotation. If necessary, check the connection to the power source, and interchange two leads
(three phase power) in order to change rotation.
If an electric motor is used to drive the pump, remove V-belts, couplings, or otherwise
disconnect the pump from the motor before checking motor rotation. Operate the motor
independently while observing the direction of the motor shaft, or cooling fan.
If rotation is incorrect consult the power source operation manual.
