How Does a Hydraulic Piston Pump Work?

how does a hydraulic piston pump work

Hydraulic piston pumps are used to power a wide range of professional equipment and industrial machinery. But there comes a time when your Caterpillar, Rexroth, Eaton or Vickers piston pumps may break down and require repair, or need replacement. Panagon Systems, a company who specializes in the manufacturing of piston pumps and offers a wide range of hydraulic pump parts, as well as hydraulic pump replacement options offers some expert insight into a commonly asked question “how does a hydraulic piston pump work?”.

The Hydraulic Piston Pump Process

Hydraulic pumps are designed to control the flow of fluid. Many of these pumps are part of hydraulic systems designed to produce energy. Once a pump is activated, the resulting pressure moves the hydraulic fluid and powers a mechanism.

These systems are incredibly powerful. A leading piston pump is capable of delivering as much as 10,000 pounds per square inch of differential pressure. This allows even the heaviest equipment to operate buckets, lifts, drills and other equipment.

The exact process is determined by the type of pump. There are five basic types of hydraulic piston pumps, and each one is used in a slightly different way to direct and control the flow of fluid. Compare these types of pumps to determine the best option for your equipment needs.

Common Piston Pump Types

Depending on the amount of pressure, size of equipment and other considerations, manufacturers choose one of these five types of hydraulic pumps. Be sure to check the type of pump in your equipment for hassle-free replacement:

  • Axial
  • Bent axis
  • Radial
  • Inline
  • Plunger

An axial pump uses a propeller to push fluid along the axis in a spiral motion. These unique pumps are common in aerospace and marine applications, including jet and torpedo use. They stand up well in high-temperature situations and can produce a particularly high flow of hydraulic fluid.

A bent axis piston pump can bend up to 40 degrees and still spin effectively. Compared to inline pumps, this type allows far more flexibility and higher spin rates.

Choose a radial hydraulic pump for high-pressure applications. These highly reliable pistons push fluid in an outward direction to distribute energy. They are typically used to generate energy, test rigs and in machinery applications.

One of the most common types of pumps is an inline axial piston pump. This type is ideal for water pressurization and is a very efficient option. It doesn’t have the same flexibility as a bent axis pump but is capable of some levels of flexible performance.

Finally, a plunger hydraulic piston pump uses a cylindrical shape to displace fluid. The back-and-forth motion of a plunger allows it to produce reliable energy with minimal maintenance. These pumps are commonly used in pressure washing and reverse osmosis projects.

Replacement Pumps vs. OEM Pumps

When your piston pump experiences performance issues, it may be time for a repair, rebuild or replacement service. Unfortunately, OEM replacement pumps and services can be a significant investment. If you have outdated equipment, you may not be able to find the obsolete hydraulic pump parts necessary to restore your equipment.

As North America’s largest aftermarket manufacturer of piston pumps, we at Panagon Systems are confident we can deliver an exceptional pump at an affordable price. Match our aftermarket pumps with the original make and model of your pump to see for yourself how we compare with OEM hydraulic components.

Replace your Caterpillar, Rexroth, Eaton or Vickers piston pumps with a Panagon Systems pump to enjoy an affordable alternative to costly or obsolete replacement parts. We carefully design and engineer pumps to restore your construction equipment, industrial press or other machinery.

Panagon Systems Pump Options

So, how does a hydraulic piston pump work? A Panagon Systems pump works by providing you with convenient replacement options that produce impressive power and long-lasting convenience. Our piston pumps are sorted by series, so you can easily find a replacement that is labeled with the same series name of the OEM hydraulic pump in your existing equipment.
