Double Suction Volute PumpDV-LJ (Large)
Download Catalog1. High efficiency
Higher efficiency has been achieved using the latest hydraulic analysis. This unique design provides power saving and CO2 reduction.
2. Enhanced suction performance
DV-LJ is operated with enhanced suction performance. Stable operation is made possible, even at lower water level.
3. 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.
4. Increased durability and reliability
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.
5. Light weight and compact
Achieved reduction in weight and size by full model change. Thus installation space is saved and easy to handle.
6. Custom design
Large capacity DV-LJ pumps are custom-design to suite with the required specification for optimum performance.
