Screw Pump
G-type single screw is a closed screw pump with internal teeth, which belongs to the rotary displacement pump. Because of its strong adaptability to medium, stable flow, good suction performance and small pressure pulsation, this pump can transport not only various flowable media, but also highly viscous media, media containing hard suspended particles or solid particles and media containing fibers, with good adjustment performance, wide range and high efficiency, so it is widely used in environmental protection, ships and petroleum.
