The hydraulic pump for construction machinery is designed to generate stable pressure and accurately transfer hydraulic power within the motion systems of heavy equipment. It is an axial piston type featuring a swash plate mechanism with an automatic pressure control system. The displacement range is between 68 and 185 cubic centimeters per revolution, with a rated working pressure up to 340 bar. The housing is made of ductile cast iron GGG45 with a compressive strength of 370 MPa. The inner cylinder surface is reinforced with a 20–25 micron hard chrome layer to minimize wear. It operates reliably between -25°C and +115°C and is built for heavy-duty conditions.
Hydraulic pumps used in construction equipment achieve overall efficiency above 95 percent and utilize optimized flow channels to reduce pressure losses. The input shaft is made of 34CrNiMo6 alloy steel, heat-treated for superior fatigue and torque resistance. The sealing system includes FKM O-rings capable of withstanding high temperatures and pressures up to 400 bar. Tapered roller bearings with a 45 kN radial load capacity ensure mechanical stability and service life exceeding 14,000 hours. These features make the pump an ideal choice for loaders, excavators, and graders.
