Description

1.What Is a Hydraulic Plunger Pump?

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.


2.Functions of a Hydraulic Piston Pump

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.


3.Technical Parameters of HENGYUHANG Plunger Pump

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

  • Operating Temperature Range: -20°C to +90°C

  • Mounting Interface: Direct replacement for CAT pumps

These specifications ensure that HENGYUHANG products function as a true CAT hydraulic piston pump replacement.


4.Application Industries of Hydraulic Plunger Pumps

Hydraulic piston pumps are widely used in multiple industries, including:

  • Construction machinery (excavators, loaders, bulldozers)

  • Mining and quarry equipment

  • Agricultural machinery

  • Industrial hydraulic systems

  • Marine and offshore machinery

  • Energy and power equipment

In these applications, both CAT hydraulic piston pumps and HENGYUHANG plunger pumps provide reliable hydraulic power.


5.Advantages of CAT Hydraulic Piston Pumps

CAT hydraulic piston pumps are trusted globally and offer several advantages:

CAT Strengths

  • Strong global brand recognition

  • Proven reliability in harsh working conditions

  • Stable pressure output

  • Long service life when properly maintained

These benefits make CAT pumps a popular choice for OEM equipment.


6.Limitations of CAT Hydraulic Piston Pumps

Despite their performance, CAT hydraulic piston pumps also have notable drawbacks:

CAT Weaknesses

  • High initial purchase cost

  • Expensive replacement parts

  • Long delivery lead times in many regions

  • Limited flexibility for aftermarket alternatives

These limitations have increased demand for a reliable CAT hydraulic piston pump replacement.
