“Hydraulic Power Units (HPUs) are custom-built to support a specific customer’s application at the fluid, flow and pressure specified. They are used to supply hydraulic power to aircraft under test and remote hydraulic consoles. Our designs employ the latest pump technology to ensure quiet, reliable operation and minimal energy consumption. Modern manifolds are used to minimize space, reduce leakage, and simplify maintenance. Our Central System HPUs are easily adaptable to a variety of electrical power supply requirements for unique in-country standards.

HPU is designed with an open or closed frame construction with easy installation, operation, and maintenance. Each unit consists of a reservoir, heat exchanger, pump/motor groups, filters, manifolds and electrical control cabinet mounted on a rigid carbon steel base and frame. Controls are manually operated and labelled for ease of use. Maintenance items such as filters and suction strainers are located for easy access.

The hydraulic circuit control components (relief valve, check valve, filter and pressure gauges) are mounted and interconnected through a remote mount filter manifold system. By using a manifold, as well as new seal technology, many of the inherent problems associated with hydraulic component interconnections are eliminated and other advantages gained. The solid metal manifold is drilled and ported to form a hydraulic circuit between the components mounted on it. This eliminates leakage related to hydraulic tube fittings, and maintenance problems associated with the replacement or servicing of in-line mounted components. Manifolds also simplify troubleshooting and system adjustments. Other advantages such as direct port-to-port connections, increased overall system efficiency, and tighter pressure control are achieved, while decreasing contamination and pressure drop.”
