A bypass attached to the discharge opening recycles part of pumped water to the intake to generate a jet flow. An ejector effect produced by the jet flow, generates suction power in the collection cup (Intake). This guarantees a stable sucking process even if water, air, and suspended matter are drawn in from water surface simultaneously.
