LX LP300 Centrifugal Water Pump: How it Works Water circulation pumps power the body jets of a tub, whirlpool bath, and other spa systems. The most common type of pump used in these is coined as centrifugal. A centrifugal pump, also known as a radial-flow pump, is a high-pressure pump built with a backward-swept rotor rotating anticlockwise. The pump speeds up water flow as it goes through the center. Water vents out of the pump in a radial manner, hence the name. A pump containing one rotor is considered as a single-phase or single-speed pump. An example of a single-phased centrifugal water pump is the LX LP300 pump. Priming and Self-Priming Pumps Air is lighter than water, hence in a manual priming pump, it will stay afloat on top of the casing. This will prevent the rotor from operating and may lead to overheating. Air and water can circulate in a self-priming, centrifugal pump. The machine itself combines both elements into a single fluid and then vents the air out. Water without air is denser than air and water combined. This allows water to move through the rotor energizing hot tub and whirlpool bath jets. Want to know more about water pumps? - Please head on to our Whirlpool Bath Buyers Guide.
