Overview:
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. They incorporate five mechanical seals for optimum protection from dust and particulate contamination, and can be mounted separately or on the inlet of the backing pump to create a compact integrated package.
Featuring an extra large diameter shaft, the Stokes 6” series has the capability for use with higher powered motors in addition to ensuring a uniquely rugged and durable mechanical booster. This allows the pumps to operate at their full displacement from atmospheric pressure with an appropriately sized backing pump.
The Stokes 6" series must be backed by a primary vacuum pump designed to discharge to atmospheric pressure. Examples of suitable backing pumps are listed below:
• Microvac series piston pumps
• GV Drystar or Chemical Drystar dry pumps
• EM or ES oil sealed pumps
• Two stage LR series liquid ring pumps
