For use with sea water, please consult the technical office. This table should be considered a general guide.
It is important to consider the specific operating conditions, in particular the concentration in the pumped liquid, the specific weight and/or the viscosity, the temperature
of the liquid and its pressure.
All these conditions are essential for engine and pump performance.
When pumping hazardous liquids, it is recommended to take safety precautions. You can contact us for more information.
OVERVIEW
All parts in contact with liquids are made of AISI 304
stainless steel (AISI 316 X versions).
DAB construction quality guarantees solidity and
greater resistance to wear and tear.
