A Guide to Discontinued Vickers/Eaton Hydraulic Piston Pumps
Hydraulic pumps are critical components of hydraulics systems because they turn electrical energy into fluid power to drive the system.
Using the wrong pump can adversely affect the hydraulics system, as the pump cannot provide sufficient fluid pressure. An improperly sized pump will also reduce a hydraulic system’s performance and power, eventually leading to overheating. So, it’s vital that you choose the right pump type and brand.
Among all the piston pump brands on the market, Vickers/Eaton is one of the most reliable brands. However, certain models will become obsolete over time, making it harder to find high-quality replacements.
Panagon Systems is a trusted manufacturer of aftermarket hydraulic piston pumps and motors from brands like Vickers/Eaton. Some discontinued piston pumps we manufacture include those in the PVM, PVB, PFB, PVE, PVH, and PVQ series.
Keep reading to learn more about each Vickers hydraulic piston pump we manufacture, including key features and specifications, to help you make the best selection.

Considerations
Selecting the right pump comes down to defining your specific application. For example, running a single piece of equipment at a fixed flow rate means you’ll need a fixed displacement pump, like a PFB pump. If your application requires that the displacement change, a variable pump will provide more versatility and efficiency.
Other considerations include the hydraulic pressure you’ll need the pump to support, the operating temperature, how frequently you’ll run the hydraulic system, space restrictions, mounting requirements, and speed
- Flow Rate Requirements (Fixed Versus Variable)
- Pressure Requirements
- Operating Temperature
- Frequency of Use
- Space Restrictions
- Installation/Mounting Requirements
- Speed Requirements
