Severe damage can be done to the pump if it is driven in reverse rotation.
During installation, when the motor is jogged to check rotation,
this MUST be done with the coupling spacer removed.
Do not install coupling spacer until correct motor rotation has been established
Operators must become familiar with the installation and service manual as supplied by the
engine manufacturer.
Drivers
Electric Motors
Connect power supply in conformance with local and national codes. Line voltage and wire
capacity must match the ratings stamped on the motor nameplate.
Engine-Drives
Safe and efficient operation of a pumping unit driven by an engine, whether diesel or gasoline
requires the installation to satisfy the following requirements:
1. Be well ventilated in order to keep the ambient temperature as low as possible.
2. Provide ample air for proper combustion.
3. Provide the engine with an efficient exhaust system so that the combustion gases
discharge with a minimum of backpressure.
4. Provide for a fuel system of adequate capacity, which meets the local codes.
5. Provide ample accessibility to service engine.
6. Provide engines / drives for correct rotation of the pump. Engine rotation is determined at
the factory. No change of engine rotation can be made in the field.
Flushing and Cooling Lines
Pump auxiliaries such as flushing and
cooling are application-specific. In
general, however, note the following:
Cooling
Bearing cooling is required for applications
with pumpage temperature above 350
0
F or
if bearings operate above approx. 180
0
F.
Bearing cooling is accomplished with a
finned-tube cooler,
