Never suspend the pump from the power cord.
4. Description of Product and Accessories
All WJ-series pumps are self-priming.AlI parts in
contact with the medium being handled are of
corrosion-resistant steel. Single-phase motors
have built-in thermal contacts, switching off the
motor on overload and on again after a cooling
down period. A mechanical seal separates the
pump housing from the motor.
