ÖÐÎÄ°æPositive Displacement Pump
GF Sanitary Single screw pump
Summary
The single screw pump is an internal meshing closed screw pump. As the rotor type positive displacement pump(the Archimedes' screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle. It has strong adaptability to the medium,which can transport various flowable medium , as well as highly viscous, fibrous, medium containing hard suspended or solid particles.

Advantage
Comparison of the screw pump and other pumps:
1. screw pump does not need to install a valve, stable flow and pressure pulsation when compared with the centrifugal pump,
2. The screw pump has strong self-priming ability and strong suction height: 5m when compared with the general pump
3. the screw pump can transport various mixed impurities containing gas, solid particles (Max.50mm) or fibers without destroying it , and can also transport various corrosive substances when compared with the diaphragm pump
4. the screw pump can transport high-viscosity substances£¬ maximum viscosity of 200,000cps and water containing rate of 50% depend on materiality when compared with the gear oil pump
5. screw pump can be used for pharmaceutical filling and metering when compared with the plunger pump, diaphragm pump and gear pump
6. Others, bearings are placed externally, fluids are not contaminated.flow direction can be changed and reversed running. Sealing is set on suction side, maintenance is easy.
