Eaton medium-pressure closed-circuit piston pumps are hydraulic pumps that use a reciprocating piston to generate flow and pressure. These pumps are designed for use in medium-pressure applications, typically in the range of 1000 to 3000 psi. They are closed-circuit pumps, which means that the fluid being pumped is contained within the pump and is not exposed to the external environment. This allows for precise control of the fluid flow and pressure and makes these pumps well-suited for use in a variety of industrial and mobile applications. They are often used in hydraulic systems for construction equipment, agricultural machinery, and other industrial applications. Eaton’s medium-pressure closed-circuit piston pumps are known for their high efficiency, durability, and reliable performance.
