Vertical Mixed Flow PumpDF-V
Download CatalogSaving Installation Cost
The motor is installed on the discharged elbow and so the pump requires less space than for the horizontal type thereby reducing installation costs.
High reliability
The motor is installed at a high elevation making it safe from flooding even during times of emergency. Because the impeller is located in the water, pump is free from cavitation and can lift water from deep wells, which is not possible with horizontal pump. Kubota’s Vertical Mixed Flow Pump has a rising characteristic (H vs. Q) from run out flow to no-flow condition and can lift water even when the head fluctuates. Pump operation is very quiet over a wide range of flows.
Easy Operation
Automatic operation is very simple because the impeller is submerged and priming devices such as a vacuum pump are not required. Unlike for axial flow pumps, shut-off operation is possible at start-up.
