G Stainless Steel Screw Pump is a new type of internal meshing rotary positive displacement pump. It has the advantages of high efficiency, strong self-priming ability and wide application range. It can be used to transport various difficult-to-transport media. Therefore, screw pumps are called universal pumps abroad. This series of pumps can transport neutral or corrosive liquids, clean or abrasive liquids, liquids containing gas or easy to produce bubbles, high-viscosity liquids, including liquids containing fibers and solid substances. Compared with centrifugal pumps: single screw pumps do not need to be equipped with valves, and the flow rate is a stable linear flow. Compared with plunger pumps: single screw pumps have better self-priming ability and can reach a suction height of 8.5 meters of water column. Compared with diaphragm pumps: single screw pumps can transport various mixed impurities, media containing gas and solid particles or fibers, and various corrosive substances. Compared with gear pumps: single screw pumps can transport high-viscosity substances. Unlike plunger pumps, diaphragm pumps and gear pumps: single screw pumps can be used for pharmaceutical filling and metering.
