5 Tips to Make Your Rotary Vane Pumps Last Longer

Rotary Vane Pump

Rotary vane pumps, also known as positive displacement pumps, are used in an array of industries and applications because they are efficient and reliable. When you choose rotary vane pumps, you’re choosing an affordable option that can last longer than some of the other pumps available on the market today.

Here are five tips to make your rotary vane pump last longer.

1) Learn how to rebuild the pump

It’s always important to maintain your equipment, but some pumps are easier than others. For example, rotary vane pumps require a bit more maintenance than other types.

A good way to make sure you’re able to keep using your rotary vane pump for as long as possible is by giving it an annual tune-up. This will help eliminate problems and ensure the pump will be in top shape for many years down the road.

2) Clean out any debris

Rotary vane pumps are often used in the mining industry for dewatering mining shafts. They move large quantities of water, slurry and ore by spinning in a circular motion. This can cause any debris or minerals to build up on the vanes and eventually wear them down.

To make your rotary vane pumps last longer, be sure to regularly clean out any debris that may have built up on the vanes.

3) Test all moving parts

It is important to maintain your rotary vane pump by inspecting the rotating shaft and seals. When you are inspecting the seal, make sure it is not worn or damaged. If it does appear compromised, replace it with a new one.

You should also check for cracks in the housing and see if there are any dents in the impeller blades. If you notice any issues with these parts, replace them as well.

4) Pay attention to lubrication

Lubrication is one of the most important aspects of keeping your rotary vane pump running efficiently. A lack of lubrication will cause the rotors and vanes to wear down prematurely, which can lead to costly repairs.

In order to avoid this issue, it is best to run the pump dry periodically and apply a light coating of oil with a paper towel.

5) Invest in proper maintenance

In order to make your rotary vane pumps last longer, it’s important that you invest in a regular maintenance plan. This will ensure that the pumps are operating efficiently and won’t break down when you need them the most.

It’s also a good idea to have them inspected annually by an experienced professional who will be able to identify any potential issues before they become serious problems.


Rotary vane pumps are a necessary component in many industries. If you want your business to run smoothly, it’s important that you keep your rotaries in top condition.
Keeping these five tips in mind can make the difference between a pump that lasts for years and one that needs to be replaced prematurely.
