(X) - Positive suction head required
1 = Good compatibility (1) Dangerous liquid (toxic, poisonous, attacks skin, irritant, etc.).
2 = Poor compatibility (2) Flammable and explosive liquid.
3 = No compatibility (3) 4-poles versions only.
(4) The stainless steel compatibility depends on the chlorine content in relationship with the liquid
temperature, a detailed analysis is necessary.
