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.
Section 4, "Service Procedures," describes
the
various
assembly
/
disassembly
procedures.
Section 5, Trouble Shooting, describes
possible problems, causes and solutions
related to pump performance.
Section 6, Rebuilding Data, Recommended
Running Clearances and Torques, presents
information useful for pump rebuilding and
assembly,
including
dimensional
and
tolerance data, running clearances for all
bearings,
and
recommended
fastener
torques.
PUMP DESIGN
The GD-2500Q quintuplex pump uses only
two major assemblies: power end and fluid
end. The gear reducer is located inside the
power end. The pump is designed with a
modular concept. Each assembly is a
module that can be assembled, handled,
installed, fixed, or transported separately
from the rest of the pump (See FIGURE 2-1,
page 9). The following is a brief description
of the essential design features for each
modular assembly.
POWER END (FIGURE 2-2,FIGURE 2-3)
The power end design is a fabricated steel
frame made from high-strength low-alloy
steel plate, joined by heavily welded cross-
members to provide stiffness and strength.
This design concept provides maximum
durability with minimum weight.
