The impeller spins to heighten the flow and pressure of water. Double and multi-stage pumps have more than one rotor. The LX JA50 single speed is a centrifugal pump, meaning it moves water by converting the flow of fluid from rotational kinetic energy into hydrodynamic energy. Water going into the pump’s rotor is accelerated by the rotor. It then flows towards the casing and egresses from the machine. Even though the engineering of centrifugal pumps is simple, it has the capacity for a high flow rate, making it a popular choice for tubs and baths.Water circulation pumps, like the LX JA50, serve a variety of purposes.
