The H1 45/53cc and 78cc single pumps have an integral electrohydraulic servo-piston assembly that controls the speed and direction of hydraulic flow.
The pumps are optimized for use around electronic controls. Control Cut Off (CCO) circuit that disables both pump controls in the absence of the proper signal to the override solenoid; an integral speedlimitation (ISL) circuit that improves vehicle braking while preventing engine over-speed; and integral pressure filtration with a filter bypass sensor and switch. The pumps have one “clean side,” facilitating machine design and installation.
