Hybrid Actuation System | Parker HAS-500

Traditional hydraulic systems deliver excellent power density, but they require bulky power units, large oil reservoirs, and hoses and fittings to link all the components together. Electromechanical actuators excel at controlling the motion, but they suffer from excessive component wear and lack the power of hydraulics.

Parker HAS is a self-contained system, which does not need external power unit, valves, or hoses needed to make a traditional hydraulic system work, and it does not suffer from the excessive component wear like electromechanical actuators. It combines the fine control of electromechanical actuators with the power density, longer life, and resistive force of a traditional hydraulic system; it is an ideal drop-in actuator for both mobile and industrial linear motion applications.

Parker HAS 500 hybrid actuator components

How does it work? An electric motor powers a hydraulic pump. The hydraulic pump forces hydraulic fluid from a sealed oil reservoir through internal valving to energize a hydraulic cylinder. All components are contained in one unit, which can be located wherever it is needed. The HAS system is one-third of the size of a traditional hydraulic system with the same power, and it produces three times the power density of a similarly sized electromechanical system.
