GPC4 series high-pressure hydraulic gear pump is designed with the technique introduced from Vickers and has been modified in its inner structure by Changjiang Hydraulic. With high-strength Aluminum extruded shell, DU bearings of large bearing capacity, and floating side panel structure, GPC4 hydraulic pump is known for high pressure, large rotating speed, simple structure, easy maintenance, reliable performance, and long service life.
In addition to independent use, multi-connection form is also available for GPC4 to meet the requirements of machine’s main unit.
hydraulic drive system for engineering machinery, mining engineering, crane machinery, etc.
GPC4 series hydraulic gear pump is an application of the advanced Vickers technique. The pump body is extruded and formed as a piece. Operators can apply 4 pumps at the same time in serial. Besides, we are now planning to design a monoblock structure type pump to match the current market, as well as to solve the oil leakage between the valve surfaces and improve the volume efficiency to 94%.
