Single screw pump is a kind of volumetric pump, which can transport various fluidity media, high viscous media, media containing solid particles, and media containing fibers. Good regulation performance and high efficiency. Widely used in sewage, medicine, daily chemical, paper, printing, food and other industries.
When the single screw pump is selected with the supplier, it will provide the field medium (preferably know the viscosity of the medium, if the medium is sludge, provide the content) temperature, flow rate and pressure. In a word, the more parameters the better, which is beneficial to pump selection.
Secondly, after these parameters are determined, the sealing mode of the pump is determined according to the medium used in the field. Sealing methods are divided into mechanical seals and packing seals. Medium requires no leakage, mechanical seal is good, but the cost is expensive. For example, the flow rate of field demand is small, it is suggested to choose mechanical diaphragm metering pump, which has lower cost, smaller size and lighter weight than screw pump. It is also convenient to replace accessories later. For example, ordinary medium sewage, sludge content, direct selection of packing seal form, good wear, easy replacement, low price.
