Problem Solving - Centrifugal Pumps
www.stuartjohnsonco.comCentrifugal pumps should never be allowed to operate in the wrong direction of rotation. If the pump is not fitted with an impeller screw the impeller may unscrew from the shaft making contact with the casing, thereby causing seizure. To ensure correct direction of rotation the motor can be started and stopped momentarily to check the
