Said impeller stainless steel corrosion resistant pumps can be semi-open structure, the structure may also be closed, in addition, pump and motor connection mode there are direct-coupled and with bearing bracket type two, pump seal cantilever mechanical seal technology, overcurrent parts and connecting frame made of stainless steel material. So, HB stainless steel corrosion resistant pumps products with corrosion resistance and reliable to use, easy to maintain, compact, low power consumption, good sealing performance and a series of advantages. Uses stainless steel corrosion resistant pumps can transport temperature no higher than 120 ℃ (direct coupling) or not more than 150 ℃ (with bearing bracket type), including (or excluding) there is a small soft particles or fibers, corrosive or health requirements liquid, widely used in food, beverage, pharmaceutical, water treatment, chemical, electroplating, dyeing, chemical and other industries use
