Type pump (screw Non-clog pump) for pumping off medium-concentration thick liquid is a new kind of pump developed by our factory which digested international latest technology. The pump is assembled with the unique vane having both characteristics of volute and centrifugal vanes, thus, the pump has both properties of centrifugal and volumetric pumps. It can transfer heavy-concentration, high-viscosity liquids, such as up to 12% paper pulp, up to13% solid contain-ing sewage, 14% sludge and 14% fiber pulp. The pump is evidently superior to whirl pump and centrifugal impurity pump in efficiency, suction force and passing force of pulp and impurity. The pump can transfer the mixture of liquid, gas and solid. Its suction head is high, its anti-corrosiveness is good, and its flow-power curve is flat, which prevent the pump from overloading. Having above-mentioned advantages, the pump is widely used in drainage system, paper, textile, wheat food, light, metallurgical, dyeing and printing industries. It is the ideal pump for transferring heavy and medium-concentration syrup, slurry, paper pulp, chemical pulp, bagasse pulp, excrement and urine, and waste liquid from slaughtering animals.
