FIGURE 3-1 Lubricant Recommendations
PLUNGER / PACKING LUBRICATION
The fluid end plungers are lubricated from a
separate lubrication pump through the
stuffing box. The lubrication pump, hosing,
and check valve to the stuffing box is not
provided with the unit.
See
"Plunger
Packing
Lubrication
Recommendation Chart," page 20, for a list
of lubricants recommended for plunger
/packing lubrication.
STARTUP AND NEW PUMP RUN-IN
PROCEDURES
A centrifugal charge pump will be required
to charge the fluid end suction manifold.
The charge pump should be sized according
to the volume to be pumped by the triplex
pump so that there is no less than 40 psi
charge when the triplex pump operates at its
maximum flow.
The first startup and several hours of the pump
run-in are performed at the factory during the
acceptance tests as a part of quality assurance
procedure. However, the new pump break-in
period process may continue for the first 80-100
hours of operation, and therefore it will be each
user’s responsibility to perform all the tasks
related to this critical period. As all moving
parts of the pump go through wearing-in
process, steel and bronze wear particles are
carried by the oil flow in the lubrication system.
The resulting contamination of the lubrication
system with the wear particles and especially
clogging of the strainer and the oil filter may
cause serious problems. To assist the user,
