A stainless steel screw pump is a positive displacement rotor pump, which relies on the volume change of the sealed cavity formed by the screw and the rubber stator to suck and discharge liquid.Stainless steel screw pumps are ideal for use with corrosive and toxic fluids because they can be sealed with mechanical seals or a magnetic clutch. The stainless steel is often an alloy that contains chromium to make it resistant to rust. They are often used in the food and beverage industry, pharmaceutical synthesis, and agriculture.Sanitary stainless steel screw pumps have a number of advantages, including: Wide range of pressure and flow, Can transport a variety of liquids, High speeds, Good absorption and self-priming ability, and Constant flow and low vibration.
