Application

Specification scope

Enhanced suction performance2

Easy maintenance3

Higher efficiency has been achieved using the latest hydraulic analysis. This unique design provides power saving and CO2 reduction.

DV-LJ is operated with enhanced suction performance. Stable operation is made possible, even at lower water level.

Achieved reduction in weight and size by full model change. Thus installation space is saved and easy to handle.

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.

This pump has been developed through optimum design using the FEM structural analysis. Furthermore, standard stainless steel impeller and shaft offers better durability and better corrosion protection.
