There are lots of types of impellers. According to the structure difference, there are more than ten types, such as paddle, open turbine, disc turbine, saw-teeth type, propeller, hydrofoil, Bulmarking type, screw, hellical ribbon, anchor and gate type, and other special types. According to the ussage, there are two types, low viscosity type and high viscosity type.Paddle, open turbine, disc turbine, saw-teeth type, propeller, hydrofoil, Bulmarking type are low viscosity type impellers, operating at rubulent conditions, the ratio of impeller diameter to tank diameter is usually 0.3 0.6. Screw, hellical ribbon, anchor and gate type are high visocity type impellers, usually operating at laminar or transition flow.Impeller, propeller, stainless steel impeller
