construction hydraulic pump , Iran

The hydraulic pump for construction machinery is designed to provide the required hydraulic power for steering, lifting, and power transmission systems. It is an axial piston type with a swash plate and automatic pressure compensation mechanism. The displacement capacity ranges from 65 to 200 cubic centimeters per revolution, with a continuous operating pressure of 320 bar. The housing is made of ductile cast iron GGG50 with a tensile strength of 500 MPa. The inner cylinder surface is coated with 30-micron hard chrome to improve wear resistance. The operating temperature range is from -25°C to +115°C, and overall efficiency exceeds 93 percent.

Hydraulic pumps for construction equipment are equipped with roller bearings supporting a 45 kN radial load capacity. The input shaft is made from hardened 42CrMo4 alloy steel for superior mechanical strength. The sealing system uses FKM O-rings resistant to pressures up to 400 bar and ISO VG 46 hydraulic oils. The 30-degree angled input shaft minimizes vibration and mechanical oscillation. These pumps deliver continuous operation up to 13,000 hours and are widely used in excavators, loaders, and bulldozers.You can order and buy construction hydraulic pump from Iran by contacting us through whatsaap and email.
