A centrifugal pump is a type of pump that uses centrifugal force. As liquid enters the eye of the impeller, it becomes more pressurized and spins around at high speeds to travel through the pump. This high-speed liquid can push other liquids up or against gravity. If you want to control how fast fluid flows through your pump, also called head pressure, you can adjust the speed of your industrial pump's impeller. With pumps for sale from United Rentals, you have options that provide high performance without sacrificing safety.
