Quick Tip: Dry running a centrifugal pump can cause damage to your pump and system.

A centrifugal pump uses the kinetic energy generated by the rotation of the impeller to transport water. Keep in mind that most of the pumps we sell are centrifugal pumps. The liquid that the pump transports is key to counteracting the heat generated by the impeller’s motion and keeping both the pump body and motor cool.

When and if the pump is run dry, there is no water to counter and slow the motion of the impeller. Speed increases past the desired point and the heat generated increases as well. This could cause sparking, overheating, melted plastic and a busted pump that needs immediate replacement. We’ve heard plenty of horror stories of warped pumps that were run dry for one reason or another. So make sure to periodically check your pump and make sure that the water is flowing smoothly and consistently to your pump.
