Bareshaft Pump

Supply Couplings
The supply couplings provide a quick method for
attaching the supply hose to the manifold.
Secondary Filter (40K Units)
A secondary filter (Figure 4) is mounted on top of the
pump for use when operating at “40K”. The filter is
not connected during 15K or 20K operation.
A pressure gauge is mounted on the filter to monitor
pressure in the filter.
A differential pressure switch is mounted in the filter
circuit to monitor proper flow through the filter. If the
filter becomes plugged and flow is insufficient, the
switch will cause the engine to shut off. “Emergency
Stop” will be displayed on the control panel.
A drain valve is located on the filter cover that allows
the operator to purge air from the filter at startup.
Fluid End Identification
A plate (Figure 5) is attached to all fluid end mani -
folds. The plate is stamped with the fluid end model
number. In addition, the plate is stamped with plung-
er size and output pressure related to that plunger
size. Refer to this plate before operating the pump.
