Industrial, construction, and agricultural hydraulic pumps
Industrial, construction, and agricultural hydraulic pumps are designed to deliver consistent oil pressure and flow in heavy-duty hydraulic systems. The pump housing is made of compacted graphite cast iron GGG40 with compressive strength up to 350 MPa. The main shaft is alloy steel 42CrMo4 with surface hardness between 58 and 62 HRC. Displacement ranges from 25 to 160 cubic centimeters per revolution, with operating speeds between 500 and 2800 rpm. The sealing system uses NBR O-rings resistant to 120°C and pressures up to 320 bar.
Industrial and agricultural hydraulic pumps are produced in gear and piston types with volumetric efficiency above 92 percent. Output flow varies by model from 10 to 240 liters per minute. Precision needle bearings and a dynamically balanced rotor reduce vibration and extend service life beyond 10,000 hours. Inlet and outlet ports use SAE fittings ranging from ½ to 1¼ inches. This design ensures stable operation, minimizes energy losses, and enhances hydraulic system efficiency in construction machinery and agricultural equipment.
