A hydraulic plunger pump, also known as a hydraulic piston pump, uses reciprocating plungers to convert mechanical energy into hydraulic energy. Compared with gear pumps and vane pumps, hydraulic plunger pumps are designed for high-pressure, high-efficiency, and heavy-duty operating conditions.
Because of their robust structure, hydraulic piston pumps are commonly used in CAT hydraulic systems and other demanding equipment.
The primary functions of a hydraulic piston pump include:
Generating stable high pressure for hydraulic circuits
Delivering precise and continuous hydraulic flow
Supporting heavy-load and long-duration operation
Improving overall system efficiency and responsiveness
A high-quality CAT hydraulic piston pump replacement must meet all these functional requirements without compromise.
HENGYUHANG plunger pump 202-1335 and 10R-0544 are manufactured to match CAT hydraulic piston pump standards.
Typical parameters include:
Pump Type: Axial hydraulic plunger pump
Rated Pressure: Up to 35 MPa
Maximum Flow Rate: High-efficiency flow output
Rotation Speed: Compatible with CAT hydraulic systems
Working Medium: Hydraulic oil
