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.

- What is the maximum operating pressure for the Eaton 72400-SJK-04?
The maximum operating pressure for the Eaton 72400-SJK-04 is up to 5,000 psi (345 bar). It also features a closed-circuit design that ensures high efficiency and improved performance. The high-pressure seals are designed for long life and reliable operation. So you can rest assured that the Eaton 72400-SJK-04 will perform reliably under demanding conditions.
- What is the maximum pressure that the Eaton 72400-SJK-04 can withstand?
The Eaton 72400-SJK-04 can withstand a maximum pressure of 210 bar (3045 psi). This is enough to meet most industrial requirements, providing superior efficiency and reliability for your application. With its innovative design, it also features a quieter operation and improved wear resistance.
- What is the difference between an open and closed circuit piston pump?
The main difference between an open and closed circuit piston pump is the amount of pressure that can be generated by the pump. In an open circuit piston pump, the pressure is generated from within the pump and is not regulated. A closed-circuit piston pump, such as the Eaton 72400-SJK-04, maintains a constant pressure level with an adjustable regulator. This type of piston pump is typically used in hydraulic systems that require precise control over pressure levels.
