Section 3, "Pump Preparation, Operation,
and Maintenance," addresses the issues of
preparing the pump for operation after
shipping or storage, the lubrication system
design and specifications, the new pump
run-in procedures, and the periodic routine
maintenance schedule. The recommended
oils, viscosity data, and crankcase oil
temperature
requirements are also
presented in this section.
PUMP DESIGN
The HD-2250 is a horizontal single acting
2250 horsepower triplex pump. It has an 8”
stroke and various plunger sizes from 3.75”
diameter through 7.5” diameter. The weight
of this pump will vary slightly due to the
various accessories, but will not exceed
12,650 pounds. Materials used in the power
end have been selected to provide long life,
and meet the rigorous demands required for
well servicing applications. All sizes of
plunger fluid ends are interchangeable on
the power end.
POWER END
The power end is available in 6.353:1 gear
ratio only. This is a “dry sump” pump
designed for pressure lubrication fed
through
various hoses and drilled
passageways to the main bearings, rod
bearings, knuckle joints, etc. Because of
the various drive arrangements for powering
these pumps, the lubrication pump itself is
not built-in. It must be sized and mounted
to suit each particular application.
NOTICE
The direction of rotation must be
such that the top side of the
crankshaft is moving toward the fluid
end.
