I-1B Underflow pump

Overview

Screw pump is a single-screw transfer pump. Its main working parts include the screw of eccentric helicoids(called rotor)and the screw bush with a double-line helicoids on its surface(called stator). Its working principle goes like this: when the electromotor drives the pump shaft to rotate, the screw rotates around its own axes one hand and rolls along the inner surface of the bush on the other, thus forming a seal cavity in the pump. When the screw rotates a cycle, the liquid in the seal cavity will advance a screw pitch forward. With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally.
Screw pump is a new type of machinery for the liquid transfer. It boasts such advantages as simple structure, safe and reliable operation, easy operation and maintenance, continuous and uniform liquid discharge and stable pressure. The metal parts contacting materials of our underflow pump all adopt top-grade stainless acid-proof steel; the shaft material is 2cr13;the bush adopts nontoxic rubber with no peculiar smell; its working temperature can reach up to 100℃. It can be used for the transfer of corrosive media like foodstuff slurry, solution or suspension containing solid grains or rubber blocks with a viscosity of 10000Pa•s. It is widely applied in such industrial sectors as food, metallurgy, construction, pharmacy and chemical industry.
