Get a quick quote

Eaton high pressure closed circuit piston pumps are hydraulic pumps designed for use in closed loop hydraulic systems. These pumps operate by using a piston to transfer fluid from the inlet port to the outlet port, creating flow and pressure within the system. The pump is sealed, meaning that the fluid being pumped is not exposed to the atmosphere, which helps to reduce contamination and increase the efficiency of the system. These pumps are commonly used in applications that require high pressure, such as in construction equipment and industrial machinery. They are also suitable for use in mobile and stationary hydraulic systems, and can be easily integrated into existing systems.
