FAQ

1What is the maximum suction lift for a self-priming pump?

For DEFU DJZ series self priming pump, the max suction lift can be 7.6m. For further details, welcome to contact us at any time.

2How do I prime a self-priming pump?

To prime a self-priming pump, ensure the pump casing is filled with water or the liquid to be pumped. Start the pump, and the impeller will create a vacuum to evacuate air and draw fluid into the pump. Once primed, the pump will continue to operate automatically.

3What is the difference between a self-priming pump and a standard centrifugal pump?

A standard centrifugal pump requires the suction line to be filled with liquid before operation and may need external priming if the pump loses its prime. In contrast, a self-priming pump can evacuate air from the suction line and pump casing, enabling it to operate without external priming.
