Refurbished Pumps Key Terms

Utilize the refurbished pumps key terms to lower material costs for your company

By Kelley Keith

Buying refurbished pumps can help keep material costs low and most refurbished pumps carry similar warranties as the new ones. In order to know which refurbished pump to purchase, it's imperative to understand the types of pumps and the companies in the industry. Some of the major types of pumps are positive displacement and centrifugal pumps. There are also refurbished dealers with a long history of selling a quality product that you can rely on. To understand the refurbished industry, you should begin by learning a few refurbished pumps key terms and then expand your knowledge base from there.

Positive displacement pumps

A positive displacement pump is one with an expanding cavity where the liquid exits out of a decreasing cavity to the discharge side of the pump. When purchasing a refurbished pump of this type it's important to inspect the cavities thoroughly to make sure it marks correctly.
Try: Review the positive displacement pumps tutorial available at the Engineering Toolbox for more information.

Cavitation

Cavitation is when cavities form in whatever liquid a pump is trying to discharge. In refurbished pumps, cavitation can cause damage to components of the pump. Be sure to ask if cavitation was the reason for the refurbishing of the pump prior to purchase.
Try: Examine the cavitation primer available at the McNally Institute.

Centrifugal pumps

The centrifugal pump is one of the more simplistic pumps on the market and can be the easiest one to spot flaws on a refurbished pump. A centrifugal pump uses engine energy to make kinetic energy and then uses that energy to move liquid in the pump.
Try: Evaluate the centrifugal tutorial available at the Pump World for further details.
