Features Our hydraulic power packs and hydraulic power units are widely used in the field of machine tools, steel industry, metallurgical machinery, plastic machinery, rubbermachinery, forestry machinery, mining machinery, building machinery, petroleum machinery, pharmaceutical machinery, chemical machinery, ceramics machinery, environmental protection machinery, leather machinery, etc.With usage of Aand AR series low noise piston pumps and fully consideration of oil tank construction and proper piping ,niose from the hydraulic system is greatly reduced Application of high efficient and pressure compensation type variable displacement piston pumps reduces power consumption ,saves energy and decrease heat. With more than over 29 combinations of pumps ,tank volumes and electric motor power capacities ,users can easily select motor is AC380V To meet the requirement of different hydraulic system ,selscted valves and base plates can be combined into all kinds of circuit.
