Description, Care and Maintenance
Diesel Powered Centrifugal Pump
Care and maintenance of the engine and pump are covered in this manual and/or the manufacturer
operator’s manuals supplied and should be read and understood. We suggest the following daily checks be
carried out prior to using the system. Check the diesel tank is full. Check oil level by removing the oil plug /
dip stick, and viewing the oil level. Check the pump seal grease cup is full (see grease cup instructions Fig.5).
Check the engine air filter (due to environmental conditions). Check that any water intake valve(s) are open
and the reservoir tank has sufficient liquid to supply the centrifugal pump.
The pump is mounted directly to the engine, so there is no “drive coupler” to check or maintain. The pump
is the primary component that will see the most wear due to the nature of the material it is handling
therefore it will require regular checks, adjustments and maintenance.
There is a section of this manual dedicated to the pump itself and should be read and understood
which will help should any problems or concerns arise in the field.
The pump should never be allowed to start or run dry, as this WILL damage the internal pump seal (grease
seal) and render the unit inoperable until the seal is fixed.
To prime the pump or check to visually see if the pump is primed, slowly undo the priming plug (see
fig. 3) on top of the pump and stop after about 3 turns. If the pump is primed, fluid & air will escape from
around the plug threads. This indicates that the pump housing is full, and the plug can be tightened back up.
If no fluid is escaping from around the threads, completely remove the plug & carefully remove the plug.
Drill fluid or water can be poured into this opening to fill the pump cavity, and a visual of the fluid level
inside the pump can be made. The level should be approximately to the top of the pump priming hole.
Another way to prime the pump is to have the tank FULL of fluid, and standing off to the side of the
hopper, rotate the hopper valve SLOWLY to the open position. As the valve is opened, you will hear air
escaping followed by fluid, into the hopper itself. Close the valve as the fluid enters the hopper. This means
the fluid in the tank has filled the pump cavity of the pump and flowed from the outlet of the pump to the
remaining piping on the unit.
CAUTION
IMPROPER INSTALLATION OF THE
MECHANICAL or GREASE SEAL
will result in leakage and possible
damage to the seal. All maintenance,
operating and repair of this unit, must be
done per the instructions in the operators
manual for safety and reliability.

DANGER
NEVER ATTEMPT REPAIRS
OR DISASSEMBLY
without shutting off the engine.
Serious personal injury will result.
CAUTION
BEFORE STARTING THE ENGINE,
BE SURE THE PUMP IS PRIMED!
Check the pump by slowly & carefully
opening the primming plug located on
the centrifugal pump.
A visual inspection can be made if the fluid
escapes around the plug as it is loosened.
Remove the plug to view inside fluid level.
The centrifugal pump seal WILL be
damaged if allowed to cavitate or run dry.
DANGER
IN AN EMERGENCY
rotate the engine speed control lever
to the STOP position
to halt engine, pump, and fluid flow
