Work Principle

Micro centrifugal pump lifting water by rotating the impeller to make the water centrifugally move. Before the pump is started, the pump casing and the suction pipe must be filled with water. After starting the motor, the pump shaft drives the impeller and the water to rotate at a high speed, which makes water into the pressurized water line of the pump. Centrifugal water pump has become the most widely used water pump in agriculture because of its simple structure, convenient use and maintenance, and high efficiency.
