Hydraulic Pump

We WONEPART have high quality original hydraulic pump parts and OEM Japan quality parts and aftermarket pump parts, such as LS valve, main relief valve, port relief valve, solenoid valve, piston shoe, cylinder block, cradles, bearing, valve plate and so on. The hydraulic pump is a power component of the hydraulic system, and is driven by an engine or an electric motor to suck oil from the hydraulic oil tank to form a component that is discharged to the actuator. The hydraulic pump is divided into a gear pump, a plunger pump, a vane pump and a screw pump according to the structure. A hydraulic component that provides pressurized liquid to a hydraulic drive and is a type of pump. Its function is to convert the mechanical energy of a power machine (such as an electric motor and an internal combustion engine) into the pressure energy of a liquid. There are many factors affecting the service life of the hydraulic pump. In addition to the design and manufacturing factors of the pump itself, it is also related to the selection of components related to the pump (such as couplings, oil filters, etc.) and the operation during the test run. The working principle of the hydraulic pump is that the movement brings about a change in the volume of the pump chamber, so that the fluid is compressed to make the fluid have pressure energy. The necessary condition is that the pump chamber has a sealed volume change. We have a wide range of hydraulic pumps for all types of construction machinery excavators. Komatsu,Hitachi,Caterpilliar,Kobelco,Case,Sumitomo,JCB,Volvo,SANY,Liugong,XCMG,XGMA, Kawasaki, Rexroth pump. Any other details, you could whatsapp us +86-15860751932
