The Hydraulic Systems Division designs and manufactures hydraulic power supplies (HPS) for aerospace applications. Their HPS product line is ideally suited for applications where a highly integrated and compact hydraulic system is needed.

The HPS is a completely self-contained, compact, gearbox-driven device that fully integrates the hydraulic pump with the filters, reservoir, switches, transducers, and ground support couplings. This compact and robust unit provides the full functionality of a conventional hydraulic system for conformance to unique weight and space constraints.

Standard and custom units are available for a variety of applications.
