HENGYUHANG Plunger Pump 259-0814 & 10R-6275 Perfect Replacement for CAT Hydraulic Piston Pump
In demanding hydraulic applications, a high-performance hydraulic piston pump is essential for stable pressure, efficient flow, and long-term reliability. CAT hydraulic piston pumps are widely used in construction, mining, and industrial equipment. However, the high cost and long delivery time of original CAT pumps have led many customers to search for a reliable CAT hydraulic piston pump replacement.
HENGYUHANG plunger pump 259-0814 and 10R-6275 are designed as a perfect replacement for CAT hydraulic piston pumps, delivering OEM-level performance, full compatibility, and superior cost efficiency.
What Is a Hydraulic Plunger Pump?
A hydraulic plunger pump, also known as a hydraulic piston pump, works by using the reciprocating motion of plungers inside a cylinder block to generate hydraulic pressure. This design allows the pump to operate under high pressure, high efficiency, and continuous heavy-duty conditions.
Because of these advantages, hydraulic piston pumps are widely used in CAT hydraulic systems and other high-load machinery.
The primary functions of a hydraulic piston pump include:
Generating stable high-pressure hydraulic power
Delivering continuous and precise hydraulic flow
Supporting heavy loads and long operating cycles
Improving overall hydraulic system efficiency
