VPS - Model C-series -Booster / Dry Screw Vacuum Pumps

Excellent corrosive gas and entrain liquid handling capabilities and realizes 10-3 torr vacuum degree

VPS dry vacuum pump includes the standard advantage of the P Series(Single Pitch) model ad following details

Low ultimate pressure, corrosion resistance, cooling effect, etc.

• Casing: Ductile Iron(Teflon Coated, PTFE)
• Screw: Ductile Iron(Teflon Coated, PTFE)
• Shaft Seals
  • Suction(Rear) : Double Lip Seal & Single Lip Seal
  • Discharge(Front) : Mechanical Seal & Lip Seal
  • Drive End: Oil Seal
• Bearings
  • Suction(Rear): Roller Bearing
  • Discharge(Front): Angular Double Ball Bearing
  • Drive End: Single Ball Bearing
• O - ring: Viton

However, the followings are also available;

• Special coatings Teflon(PFA), NIFA, Ni Plated, etc
• Special O-rings such as Kalrez
• Special Mech. Seals like Hastelloy, Ni-resist
• Special material – Stainless Steel, Titanium

The dry vacuum pumps can operate continuously in all the ranges of pressure from the atmosphere to the ultimate pressure, and it can reach 0.0075Torr(1Pa) by itself and has high efficiency.

Corrosion Resistance Design

• Suitable for pumping Toxic, Corrosive, and condensable gas by special coating (PTFE, PFA, Ni, NIFA).
• Prevents condensation of corrosive gas through lowering vapor pressure by the gas ballast.

Cooling Effect is good

• No Cooling Gas necessary.
• Unique hydrodynamic spiral jacket structure.
• Reduce discharge temperature greatly & close to the T4 requirement.

Power Consumption

• Variable pitch screw design.
• Power consumption reduced by 30%

Smooth discharge structure

• The short gas path through the pump makes quick gas discharge
• Smooth condensate draining within the pump
• Excellent liquid handling ability

IEC Flange (NEMA Optional)

• Mostly C-flange design Simplified mounting reduces noise level and eliminate shaft alignment
• Rib enhancement for deformation and vibration prevention

Grease leakage prevention

• Triple single lip seal
• Applied the optimized grease space
