Working principle of double suction pump
2025-08-22
Mainly based on pressure difference and centrifugal force. When the double-suction pump starts working, both of its inlets form negative pressure areas, and the liquid is driven by the pressure difference to flow from the supply system to the pump's suction inlet. After the liquid enters the pump chamber through the suction inlet, the pump rotor begins to rotate. The rotor usually consists of an impeller and a shaft, with the impeller responsible for transferring the liquid. As the rotor rotates, the liquid is pushed to the pump outlet; the rotor's rotation generates centrifugal force, pushing the liquid toward the outlet and increasing its pressure. After the liquid is pressurized into the outlet, the pump discharges it into the corresponding pipeline or container.
