A8VO140 A8VO120 A8VO200 Uchida Rexroth Hydraulic Piston Pump For Excavator
The A8VO140 A8VO120 A8VO200 Uchida Rexroth Hydraulic Piston Pump is a high-pressure piston pump used in hydraulic systems for excavators. It has a variable displacement, making it suitable for hydrostatic drives in open circuits. Its flow is proportional to the input speed and displacement, and is infinitely variable from q V max to q V min.
Common Usage Scenarios
This piston pump is widely used in construction machinery, forestry machinery, agricultural machinery, lawn care equipment, material handling equipment, and concrete mixer trucks. It is ideal for direct mounting on the flywheel case in diesel engines.
Product Features and Benefits
- Variable double pump with two axial tapered piston rotary groups of bent-axis design
- One common suction port for auxiliary pump and both circuits
- Wide range of control instruments for different control and regulating functions
- Integrated auxiliary pump with pressure-relief valve
- Power-take-off for mounting axial piston and gear pumps
- High power-to-weight ratio
- Long service life
The A8VO140 A8VO120 A8VO200 Uchida Rexroth Hydraulic Piston Pump is designed with a high volumetric efficiency, small leakage, and can operate under high pressure. It is suitable for high-power hydraulic systems, but the structure is complex, and material and processing precision are high, which leads to a higher cost and greater oil cleanliness requirements.
Installation, Maintenance, and Repair
Before operating the piston pump, make sure the mounting is secure, the screws are tightened, and the coupling is installed correctly. Fill the pump body with oil and make sure the inlet and outlet ports are in the proper rotary direction. During operation, do not start up quickly with full speed, but rather, before continuous operation without load, press the switch of the prime mover for some moments to drive out the air in pipes.
If there will be a long time of no running, clean the oil out of pumps and fill it with low acid oil. To protect against corrosion, paint anticorrosive oil on the surface of pumps and plug the ports.
