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 19, 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 50 psi
charge when the triplex pump operates at its
maximum flow.
The first startup is 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 our
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 a 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 can cause serious problems. To
assist the user, the following guidelines are
presented for the maintenance personnel to
follow during the critical startup and break-in
period:
1.
Fill the lube oil reservoir with the
recommended grade of oil. See
FIGURE 3-1 above for Lubricant
Recommendations.
