Vacuum Pump
VSP Series Dry Screw Vacuum Pump
Dry screw vacuum pumps operate with two screw rotors rotating in opposite directions. This traps the medium to be pumped between the cylinder and the screw chambers and Transports it to the gas discharge. A vacuum is formed by the principle of suction, Compression, and discharging through passing regular intervals of two small pitches. Hybrid Combined Variable Pitch is a screw type to remedy the disadvantage of Single pitch and adjustable pitch compared to conventional single pitch.

Dry Screw Vacuum Pumps for Industrial ApplicationsÂ
Dry screw vacuum pumps are straightforward yet sophisticated, reliable, and highly efficient. The dry and contact-free operation requires no lubrication in the pumping chamber. This translates into major advantages: no process contamination and no pollution caused by the pump operation. Dry vacuum pumps can safely and reliably handle corrosives, organics, inorganics, and solvents because of their oil-free, non-contacting screw design. Key applications include:
- Distillation (normal, short path & molecular)
- Drying (filter, freeze, and transformer drying)
- Evaporation
- Filtration
- House vacuum (central or general/laboratory vacuum service, pilot plants)
- Reactor service
- Solvent recovery (fuel vapor)
- Sterilization (ethylene oxide)
- Problem gasses (flammable, low auto-ignition temperatures, corrosive gasses, and hydrogen)
- Conveying
