Product Description

Accu-Steer HPU100 offers adjustable flow rate operation (0.1 - 1.0 gal/min) and consists of a running continuous running pumpset and flow control that is second to none in performance and dependability. It accommodates steering systems of 50 cu. in.


The Accu-Steer HPU100 is a complete pump assembly consisting of a piston pump, hydraulic lockvalves and an electric permanent magnet motor with a connection/relay start box. As the pumpset is self-contained, installation involves connection the pump to the steering lines and the electric control and adjusting the unit to the requirements of the steering system.


The pump is a piston style unit with an adjustable swash plate. Adjusting the angle of the swash plate varies the piston stroke and therefore the output flow. It also features adjustable pressure relief valves, oil suction make up valves and output lockvalves. The lockvalves are double pilot operated check valves, which prevent oil from the steering system from entering the electric pumpset when it is not in use. The pressure relief valves are factory set for 500 psi and should not be altered in the field.


The electric motor is a permanent magnet style D.C. motor featuring ball bearing supports and replaceable brush gear. The motor has a soft anti-vibration foot mount and a soft jaw shaft drive coupling which results in very quiet operation. The motor/pump alignment is accomplished through a machined pilot bore.


The electric box features a remote start relay and thermal overload along with oversized terminals for easy connection. The thermal overload is sized for proper motor protection. Refer to the drawings for the layout and wiring schematics.
