You heroes water pump, stainless steel impeller and bronze impeller what is the difference?
Stainless steel impeller use longer and longer, sanitary cleaning, bronze impeller is more resistant to corrosion, mainly used in the 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).
The price is different: 304 stainless steel impeller compared to bronze almost, 316, 316L, two-way stainless steel prices much higher.4, different materials, different levels of environmental protection:
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. (learn from Baidu experience)
