What should I do if the centrifugal water pump is hot?

(1) The pan is too tight or not saturated with oil. Readjust or replace.

(2) The balance plate is heated. The drain pipe is too dirty or the valve on the pipe is not open, clean or open the valve.

(3) The pump casing is hot. When the gate is closed or there is no water, the pump work time is too long; stop the pump to cool, and then pay attention when starting.
