INSPECTING THE PUMP PARTS
A. Pump Housing should be smooth inside and
not show any rough spots.
B. Both spindles should show smooth surfaces,
not be worn from touching or show splintered
corners.
C. Both pump shafts need to sit tight without any
play or wiggle room in axial and radial direction.
If any, there could be very minimal play from
the gear wheels. Grip both shafts and wiggle up
& down, forward & backwards, and also side to
side, to check for excessive wear.
D. If even small movements are detected, it will
require a complete bearing replacement before
further operation.
E. Inspect both mechanical seals for visible wear
and tear. In case the seals are worn, please send
it to
for refurbishing.
