the single-stage double-suction split volute centrifugal pump achieves continuous liquid delivery through the high-speed rotation of the impeller and the action of centrifugal force. Its working principle is simple and efficient, and it is widely used in water treatment, water supply and drainage systems and other projects.

The self-priming centrifugal pump generates negative pressure through the rotation of the impeller, sucks in liquid and air, and then uses centrifugal force to separate the liquid from the air in the mixture, ultimately achieving continuous liquid delivery. This pump has the advantages of strong self-priming ability, simple structure, and stable operation, and is widely used in industrial and civil fields.

the stainless steel sewage pump drives the impeller to rotate through the motor to generate centrifugal force, and uses the pressure difference to drive the sewage flow, thereby realizing the transportation and discharge of sewage.
