GWSPS Oil free Scroll Vacuum Pump
Working principle:
GWSPS oil free scroll vacuum pump is constructed with pump head assembly, crank pin assembly, bracket assembly, air flush assembly, and exhaust valve assembly. Two spiral cylinders, one offset and orbiting against the other fixed with an offset of 180° to form several crescent-shaped pockets of different sizes. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gas from outside towards the inside thereby pumping the gas from vacuum chamber.
Basic informations:
1) Model: GWSPS300 Oil free scroll vacuum pump
2) Ultimate vacuum pressure: 8.0Pa/0.08 mbar (abs.)
3) Max suction capacity: 50Hz-4.4l/s 60Hz-5.3l/s
Safety Precautions:
The GWSPS series oil free scroll vacuum pumps are suitable for clean processes only.
Do not pump toxic, explosive, flammable or corrosive substances or substances which contain chemicals, solvents or particles.GEOWELL will not perform maintenance work on pumps which have used special gases or other hazardous substances.
Be sure the inlet gas temperature must be lower than 122 °F.
