HENGYUHANG Plunger Pump 169-4883 & 10R-3875 Perfect Replacement for CAT Hydraulic Piston Pump


In heavy-duty hydraulic systems, a reliable hydraulic piston pump is essential for stable pressure output and efficient power transmission. CAT hydraulic piston pumps are widely used in construction, mining, and industrial machinery. However, the high cost of original CAT pumps and long lead times have encouraged many users to look for a dependable CAT hydraulic piston pump replacement.


HENGYUHANG plunger pump 169-4883 and 10R-3875 are engineered to be a perfect replacement for CAT hydraulic piston pumps, providing OEM-level performance, full compatibility, and a more cost-effective solution.


What Is a Hydraulic Plunger Pump?


A hydraulic plunger pump, also referred to as a hydraulic piston pump, generates hydraulic energy through the reciprocating motion of multiple plungers inside a rotating cylinder block. This structure allows the pump to operate under high pressure, high efficiency, and continuous working conditions.


Due to these characteristics, hydraulic piston pumps are commonly used in CAT hydraulic systems and other demanding applications.


Functions of a Hydraulic Piston Pump

The main functions of a hydraulic piston pump include:

  • Generating stable high-pressure hydraulic power

  • Delivering continuous and precise flow output

  • Supporting heavy loads and long operating cycles

  • Improving overall hydraulic system efficiency
