622 5H25
Activair.cz > Products > Vacuum pumps and vacuum stations > Mechanical Boosters > Stokes 6" > 622 5H25
Stokes 6" series process isolation boosters are designed to be used in conjunction with rotary-piston, dry vacuum, rotary vane and liquid ring pumps to increase pumping speed at working pressures and shorten pump down time significantly.
Features and Benefits
- Mechanical shaft seal – improved life and serviceability
- Ringfeder® keyless gear locking system – stronger, faster timing
- Large shaft diameters – allowing improved performance at high pressures
- Belt drive or direct drive capability
- Vertical or horizontal gas flow
- Drive end roller bearing – resists belt pull and thermal effects
- Over-sized anti-friction bearings – increased uptime and longer service intervals
- Rugged proven design and construction
- Quiet operation
- Unique impeller design -Dynamically balanced to minimize vibration
- High volumetric efficiency
- High differential pressure – operation capability
- Available by-pass option for improved pumpdown
- Available process isolation seal option – optimum protection from dust and particulate contamination
Applications
- Automotive
- Chemical processing
- Heat treatment
- Leak detection
- Metallurgy
- PET processing
- Pharmaceuticals
