The two-stage excavator pump is an axial piston or gear hydraulic pump designed to supply hydraulic power for movement and implement systems of excavators. Typical operating pressure ranges from 250 to 350 bar, with flow rate per stage between 20 and 80 liters per minute. The two-stage design allows simultaneous supply for travel and implement circuits, with volumetric efficiency above 90 percent. The pump body is made of steel or aluminum, and the hardened steel drive shaft with precision bearings ensures stable operation, reduced vibration, and low noise.

Structurally, the two-stage excavator pump consists of a dual-stage cylinder block, pistons or gears, swash plate or vane mechanism, drive shaft, and reinforced bearings. Seals are made of Viton or NBR to resist heat and oil. Precise contact between pistons or gears and the swash plate minimizes internal leakage. The pump can be mounted directly on the motor or gearbox, with an operating temperature range from -20 to 120°C. It is designed for excavators and heavy machinery.You can order and buy pump from Iran by contacting us through whatsaap and email.
