Excellent corrosive gas and entrained liquid handling capabilities and realizing 10-3torr vacuum degree
▶ Vps dry vacuum pump includes the standard advantage of the P Series(Single Pitch) model and following details (Low ultimate 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
-
Cooling Effect
- No Cooling Gas necessary.
- Unique hydrodynamic spiral jacket structure
- Reducing discharge temperature greatly & close to T4 requirement
-
Corrosion Resistance Design
- Suitable for pumping Toxic, Corrosive and condensable gas by special coating(PTFE, PFA, Ni, NIFA, PEEK)
- Preventing condensation of corrosive gas through lowering vapor pressure by the gas ballast(N2cooling purge)
-
Power Consumption
- Variable pitch screw design
- power consumption reduced by 30%
Characteristice of
VPS-C Series Dry Vacuum Pump
Reliable seal structure
Mechanical seal and lip seal applied
Dry vacuum pump exclusive mechanical seal.
Use of air & N2 purge in front of Mech. seal for protection from dust & etc.
Applid variable pitch screw
Prevention of coating damage by pump temperature rise
30% reduction in power consumption 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(133Pa)
Spiral coolant jacket
Excellent cooling efficiency of the spiral jacket
Low operating temperature
Controlling temperature inside the pump with a small amount of coolant
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
