2 KUBOTA Double suction volute pump DV-L type J series The double suction volute pump with higher efficiency and enhanced suction performance. The double suction volute pump DV-LJ is the latest pump series developed by KUBOTA, following an extensive feedback from major customers. As an advanced pump, the DV-LJ provides a total reliability and better cost-performance. The DV-LJ series is available in rich line-up and can be useful in various applications. Features Application High efficiency City Industry Higher efficiency has been achieved using the latest hydraulic analysis. This unique design provides power saving and CO2 reduction. Enhanced suction performance Incorporated shaft seal water piping into the casing For water intake, water conveyance, pressurization, water distribution, front and back wash etc. Irrigation For agriculture, drainage etc. For water supply, cooling water circulation etc. Building, air-conditioning For water supply, fire-extinguish, etc. DV-LJ is operated with enhanced suction performance. Stable operation is made possible, even at lower water level. Easy maintenance Easily replaceable string-shaped rubber gasket is employed for the upper and lower seal face, and the shaft seal water piping is incorporated into the casing. Maintenance time is shorter since a number of parts have been reduced.
