Benefits of Compact Closed-Circuit Pumps for Mobile Hydraulic Applications

Benefits of Compact Closed-Circuit Pumps for Mobile Hydraulic Applications Paver Hydraulic Pump and Power SystemsDoing more with less is a common theme in business and the pump market for medium-duty applications is no exception. With the overall hydraulic system size becoming increasingly smaller and smaller, mobile, medium-duty end-users in industries such as construction, agriculture, material handling, oil and gas, and transportation industries are in search of a flexible, high-performance compact pump.

With two hydraulic pump loop options, open circuit or closed circuit, a closed circuit loop saves valuable system space by offering continuous fluid flow without the need for additional parts. In comparison, an open circuit loop typically requires a larger reservoir and as a result, increases the system’s footprint. To fulfill the market’s need for smaller hydraulic components, Parker recently introduced the PC3 Compact Closed Circuit Pump. This article explores three primary benefits of the PC3 pumps:

 

1. Compact size

On-trend with hydraulic mobile systems decreasing in size, each system component has to do more in order to save valuable system space. PC3 is a solution for this market trend with a closed-circuit design, resulting in fewer components than an open circuit hydraulic pump. In addition to the closed-circuit design, it also offers a built-in bypass valve and hot oil shuttle valve eliminating the need for third-party components, conserving valuable system space.

To achieve greater system efficiency and streamlined performance, PC3 includes a variety of features, such as:

- A hydraulic pressure override to ensure that the prime mover is not loaded in excess

- A built-in hot oil valve to increase operational efficiency and reduce system complexity

- Cross port reliefs to prevent system overload by limiting the maximum pressure in your system

 

Each of these features ensures system performance and efficiently deliver the exact power required for each unique application.

 

3. Flexibility

Finally, Parker’s PC3 offers the hydraulic pump market flexibility through various product features and sizes to use in a wide variety of applications.

PC3’s modular and interchangeable controls include options for a manual servo, hydraulic proportional and electric proportional controls, providing end-users with further customizations.

Resources

When designing hydraulic systems for mobile equipment, getting the right pump is crucial. Resources are available to help ensure the right selection is made—use an online configurator for assistance in selecting the best compact closed-circuit pump for the application. Full system supplier such as Parker can also assist with overall system designs that optimize all of the components to work together.
