Designed
for reliability and long life, the high-efficiency hydraulic gear
pumps provide high-speed positioning and maximum working pressure.
The gear pumps may have integral adjustable unloading valve in single
or multiple configurations. They are high performance pumps with
a long pump life, low noise level and compact size with pressure
compensator, load sensing and torque limiting controls.
Hydraulic gear pumps are used in a
wide variety of machines, for example agricultural and construction
vehicles to provide flexible power from the engine to lifting gear
or ancillary equipment. Standard options allow the specifier to
custom design a complete system and reduce component cost and assembly
time.
The basic gear pump consists of two
meshed gears, a case or housing to encompass the gears, and two
cover plates that enclose the ends of the gears. Each gear is mounted
on a shaft supported on bearings in the end covers. Out of these,
the drive shaft is coupled to the prime mover or the drive motor.
