The difference between pump impeller material, cast iron, stainless steel and bronze
Material corrosion resistance grade is different: stainless steel impeller use longer and longer, sanitary cleaning, bronze impeller is more resistant to corrosion, mainly used in fire, sea and other occasions, but there is no stainless steel impeller. (except tin bronze, this material is much better than stainless steel and is better at price).
4, different materials, different levels of environmental protection:5, the temperature conditions are different: Bronze resistance to low-temperature performance is outstanding, 100 degrees below zero intensity will not drop. For stainless steel, chilling temperatures, brittle like glass. At room temperature, the mechanical strength of stainless steel is higher.
Efficiency is different: the use of stainless steel impeller higher efficiency,3, the price is different: 304 stainless steel impeller compared to bronze almost, 316, 316L, two-way stainless steel price is much higher.
