SECTION 3
PREPARATION, OPERATION AND MAINTENANCE
DANGER
Read and understand clearly all
safety rules and precautions before
attempting to operate the pump.
This section deals with pump preparation
after shipping and storage of the pump, user
built
lubrication system and its
specifications, pump break in procedures,
recommended oils, allowable crankcase
operating
temperatures, viscosity
conversion tables, and routine maintenance
schedule.
PREPARATION AFTER SHIPPING AND
STORAGE
All pumps are shipped dry and therefore
must be flushed with light weight oil before
operating. The flushing must be performed
regardless of method or duration of the
shipment or type of container the pump was
shipped in.
Pumps are not prepared for storage and
should be put in service as soon as
possible.
If for any reason the pump has to be put into
storage after prior use, the following
procedure should be followed:
1.
Clean and flush the fluid end with a
rust preventative.
2.
Plug all discharge and suction
openings.
3.
Drain oil from the power end and the
gear reduction unit.
4.
Flush the power end with a rust
preventative (before flushing make
sure that the rust preventative will not
clog the oil passages).
5.
Remove the breather and either plug or
tape the opening.
6. Coat the gear reducer input shaft and
all exposed bare metal with a heavy
rust preventive.
7.
Plug drain holes at the bottom of the
pump frame, at the rear of the pump,
and the gear reducer drain.
8.
Plug the lube inlet in the lube manifold.
9.
Store the pump inside in a warm dry
place.
10. If the pump is shipped ocean cargo, it
must be crated in a water-tight contain-
er placed below the deck to prevent
rusting and salt water contamination.
PUMP MOUNTING INSTRUCTIONS
Because of the lightweight, low stiffness
nature of these pumps, it is easy to twist or
distort the frame during installations.
Therefore, it is necessary to follow this
procedure to shim the feet of these pumps.
This requires (4) grade 8, 1.00” diameter
cap screws of the appropriate length,
lockwashers, nuts, if required, and shims if
required.
1.
Set the pump in its location.
2.
Using a feeler gauge, check under the
feet at all four boltdown locations.
3.
Select the proper number and
thickness of shims to fill the gap under
the high foot. Note it is better to use
shims up to .005” too thick than to
leave any gap under the foot.
4.
With shims in place, install bolts in all
four locations.
CHARGING PUMP REQUIREMENT
A centrifugal pump will be required to prime
the fluid end suction. The centrifugal pump
should be sized to generate a minimum of
50 PSI at maximum flow. Increased
pressure is required for pumping higher
volumes, heavy sand concentrations, and
