Single Screw Type Displacement Pump

G type single screw progressive cavity pump is compact, small, easy to maintain, and well-adapted to medium, stable flow, also with small pressure fluctuation and strong self-priming ability. This Mono Screw Pump has metal lined with rubber stator, which is made of various elastic materials, such as NBR rubber and Silicon rubber. G type screw pump could pump high viscosity fluid and medium with hard suspended solid/fiber as well. It has good adaptability to the medium,smooth flow, small pressure pulsation and high self-priming capacity. Its working temperature could be as high as 120℃ (248℉). This pump is suitable for conveying lubricating or non-lubricating media, corrosive media, media containing a small amount of tiny solid particles, media with low viscosity to very high viscosity, etc. in industries such as chemical industry, pharmacy, electroplating, printing and dyeing, papermaking and electric power. It is also widely used in construction field, foodstuff and beverage industries by adopting silicon rubber stator. It can be equipped with gear box motor, electromagnetic speed adjustable motor, CVT motor, frequency inverter motor, etc.
