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.

FAQS

  1. Can I use the Eaton 72400-SPK-04 in an open circuit application?

    The Eaton 72400-SPK-04 is designed to be used in a closed circuit application, but it can also be used in an open circuit application if needed. We suggest that you consult your system requirements and carefully consider all safety concerns before making a decision.

  2. What is the maximum pressure that the pump can handle?

    The Eaton 72400-SPK-04 Closed-Circuit Piston Pump is designed to handle pressures up to 400 bar (5800 psi). This makes it an ideal choice for applications that require high pressure pumps. The pump is designed with a robust construction, ensuring maximum durability and long lasting performance.

  3. What is the difference between a closed-circuit and an open-circuit piston pump?

    Closed-circuit piston pumps, such as the Eaton 72400-SPK-04, are designed to maintain pressure in a closed system. This means that the pressurized fluid is recirculated within the same loop rather than being exhausted out of a primary port. On the other hand open-circuit piston pumps will exhaust the pressurized fluid from a primary port, which can be used for other applications.

  4. How many GPM does this pump deliver?

    The Eaton 72400-SPK-04 Closed-Circuit Piston Pumps delivers up to 54 GPM, the ideal flow rate for most industrial and commercial applications. The pump is designed for high efficiency and durability, making it a great choice for your hydraulic needs.
