Types of Hydraulic Pumps and How to Repair Them

Share This:

At Global Electronic Services, we’re often called upon to service hydraulic pumps. Hydraulic pumps are an important part of a wide variety of manufacturing processes. If you use them in your industry, you need to have them up and running at maximum efficiency as often as possible.

We have seen and repaired all types of hydraulic pumps and can get yours back to you fast if you should have a problem. Here is a little more information about the types of hydraulic pumps we service and how we service them.

What Are the Different Types of Hydraulic Pumps?

There are three main types of hydraulic pumps that you will encounter — piston pumps, vane pumps and gear pumps.

3 Types of Hydraulic Pumps

  • Piston Pumps: Piston pumps are the most common and also the most capable of complex jobs. These are the hydraulic pumps you are most likely to find in manufacturing situations. They are the pumps you will use in high-pressure applications. A piston pump is a positive displacement pump that uses a high-pressure seal working reciprocally with a piston to move water. This configuration allows them to operate under high pressure without noticeably affecting flow rate.
  • Vane Pumps: These are less common and simpler pumps that you can use for lower-pressure applications with high flow rates. Vane pumps are positive displacement pumps that can work with a number of different vanes, including flexible vanes, swinging vanes, rolling vanes, external vanes and sliding vanes. As the rotor of the motor rotates, the vanes sweep liquid to the opposite side of the cavity inside the motor and squeeze it through discharge holes in the cam.
  • Gear Pumps: This is the most basic hydraulic pump you can use. You will typically use this pump for single, basic applications. Gear pumps work by using two gears which mesh to displace water. The gears rotate together, creating suction as they separate, which draws water into the pump — water it then displaces when the gears mesh together.

 

Common Hydraulic Pump Issues

The most common problem you will encounter with any hydraulic pump is wear. Like all mechanical parts, hydraulic pumps wear out eventually with use. Contamination and heat issues are the most typical cause of premature wearing-out when it comes to hydraulic pumps.

GES Hydraulic Repair Process

Although familiarity with all of the different types of pumps is a requirement for all of our trained technicians and definitely facilitates the repair process, the problems that hydraulic pump issues face and the way we resolve them is fairly similar for all types of hydraulic pumps.

We start by fully disassembling the hydraulic pump so we can see each part to try to visually identify what is causing the problem. Once we find what is creating the issue, we will repair it if possible. If not, we’ll replace it with a new OEM part. We will then reassemble the pump and test it to make sure it is operating according to original specifications.

We will replace any worn-out parts with new ones so that when you get your hydraulic pump back, it will be like-new. To ensure your confidence in our repair, we offer our 18-month in-service warranty.

In addition to our promise that you will get back a fully functioning hydraulic pump — usually in five days or less from the time we receive it — you will also appreciate that we have the lowest price anywhere when it comes to hydraulic pump repair. If you can bring us a verified competitor’s price for hydraulic pump repair that is lower than ours, we will beat it by 10 percent.
