Product Overview
The HYDROMAX HGP-22A-F4+4R combines two gear-pump sections in one tandem assembly. This arrangement allows two hydraulic circuits or two flow requirements to be driven from a common shaft, depending on the machine design.
For a replacement inquiry, the complete model is a useful starting point, but the old pump should still be compared section by section. Displacement, rotation, shaft, ports and mounting details can differ even when pumps have a similar body shape.
Typical uses include industrial machinery, mobile equipment and replacement hydraulic power systems that require two pump sections. Both section specifications must be matched to the original circuit.

Compatibility / Selection Notice
Do not select a tandem gear pump from appearance alone. Both pump sections must be checked for displacement and function, and the direction of rotation must suit the drive arrangement.
The shaft, flange, mounting holes, port threads and port orientation should be compared with the old unit or a controlled dimensional drawing. Final hydraulic suitability and installation should be confirmed by qualified technical personnel.
