VPS®C Series Dry Screw Vacuum Pump
(Variable Pitch Screw Pump)
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 utimate pressure, corrosion resistance, cooling effect, etc.)
Low Ultimate Pressure
The dry vacuum pumps can operate continuously in all the ranges of pressure from atmosphere to the ultimate pressure, and it can reach at 0.0075Torr(1Pa) by itself and has a 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 T4 requirement.
Power Consumption
- Variable pitch screw design.
- Power consumption reduced 30%
Characteristics of VPS-C Series Vacuum Pump
Reliable seal structure
● Mechanical seal and lip seal applied.
● Dry vacuum pump exclusive mechanical seal.
● Protect from dust & etc to purge Air & N2 in front of mechanical seal.
Applid variable pitch screw
● Prevention of coating damage by pump temperature rise
● Reduction of power consumption by 30% by energy-saving design
Vacuum degree improvement
● Reaches the maximum vacuum degree 0.0075Torr(1Pa)
● Increase pumping volume from high vacuum
● Maintains stable volume from atmospheric pressure up to 1Torr
Spiral coolant jacket
● Excellent cooling efficiency of the spiral jacket
● Low operating temperature
● Controls temperature inside the pump with a small amount of coolant
Material of construction
● 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

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
Smooth discharge structure
● Short gas path through the pump make quick gas discharge
● Smooth condensate draining within the pump
● Excellent liquid handling ability
IEC Flange (NEMA Optional)
● Mostly C-flange design Simplified mounting reduce 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
