High efficiency
- Higher efficiency has been achieved using the latest hydraulic analysis. This unique design provides power saving and CO2 reduction.
Enhanced suction performance
- 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.
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.
Light weight and compact
- Achieved reduction in weight and size by full model change. Thus installation space is saved and easy to handle.
Applications
- City Water Supply
- Desalination
- Irrigation
- Petrochemical Industry
- Power Plant
- Steel Industry
