WARNING
The GLH series pump parts are not interchangeable with previous designs unless the factory
has approved to convert the old design to a GLH design using a modification kit. The
modification kit along with the identified GLH major kit will be required to make the conversion.
By design, all rotor sets are hydraulically balanced in the radial direction. Idler rotors (40 and 41)
are balanced axially by internally transferring high pressure oil from the pump discharge end to
the pump inlet end (thrust end). The high pressure oil is transferred to the pump inlet end
through bores that have been drilled axially through the rotor housings (83 and 28).
In order to provide axial hydraulic balance on the power rotor (11), a balance piston (17) is
provided. The sizes of the balance piston (17) and the balance piston bushing (18) in which it
