Does Your Company Use A Regenerative Pump? 2 Tips To Keep It Maintained

by Jared De Hooge

A regenerative pump, also known as a turbine pump, uses fluid to generate the pressure from the pump. The pump has an impeller that is used to apply force to the liquid to make it move. If your company uses regenerative turbine pumps, it is important to keep them maintained. This will ensure the pump lasts you a long time, which can save you money. Below are two tips to help you get started.

Set Up a Preventive Maintenance Program

You should set up a preventative maintenance program to ensure this gets done. The impellers, pump bearings, and mechanical seals should be examined periodically for excessive wear. The fluid chemistry should also be maintained and monitored. You need to clean the suction strainers on a regular basis. The relieve valves need to be tested also. This will help prevent any problems so you can keep your business running smoothly.

Purchase a spare parts kit from the regenerative pump's manufacturer to keep on hand so if something does happen you will have the parts to repair the pump. You could also purchase a duplicate pump to have on hand in case your pump goes down completely.

Protect the Pump

If the centrifugal pump is shut off completely while it is running this will cause problems. Fortunately, you can protect it if this is done. For example, you may have an employee that accidentally shuts it off or your power could go out. If the pump is not protected, this could damage the mechanical seals and the motor will overheat, which may result in you having to replace the motor or the entire pump.

To keep the pump protected in case something like this happens, keep the system valves open and ensure the pipes are not restricted from anything before the pump is started up. You should use a relief valve and an over pressure cutout system to help protect your centrifugal pump from this type of damage.

You also need to protect the pump from dry running. You can do this by making sure the system valves are open and the pump suction should be completely flooded before the pump is turned on.

Talk with the manufacturer that you purchased your centrifugal pump from to learn more maintenance tips. They can go over the above information with you also if you are not sure how to do any of these things.
