Single screw is by turning gear coupling volume type working principle of new type of pump, the main working parts are eccentric screw (rotor) and fixed lining (stator) use a variety of flexible materials for the stator is made, to the pump for high viscosity fluid conveying and containing hard particles in suspension medium or containing fiber media delivery, each stage pump output pressure is 0.6MPa, head 60m (water), self-priming height in 6m, applicable to the conveying medium temperature of 80 degrees Celsius, other pumps are not competent characteristics.

The little pump parts, compact structure, small volume, easy maintenance, the rotor and the stator is the pump wearing parts, simple structure, easy to assemble and disassemble.
