-
Energy-efficient operation: The IE3/IE4 motor technology is adopted, and the optimized efficiency reduces the life cycle cost.
-
Good mechanical seal performance: Bidirectional, force-flushed mechanical seal.
-
Component characteristics: Replaceable neck rings, permanently lubricated and generously sized ball bearings, low NPSH value, and good cavitation characteristics.
-
High-efficiency energy-saving and long-life design: The improved hydraulics ensures high overall efficiency, the IE3/IE4 motor saves energy, and the easily replaceable and standardized components (such as spacer couplings, bronze neck rings) extend the service life.

The performance curve chart of the pump is provided, showing the change of head (H/m) of different models at different flow rates (Q/m³/h).
