Overview
Used in conjunction with rotary-piston, liquid ring, rotary vane and dry vacuum pumps, BOC Edwards 6" superblower series will increase pumping speed at working pressures and shorten pump down time significantly. Whether your objective is to reduce valuable time from the front end of
your pumping cycle, or to substantially boost pumping capacity for high out-gassing applications, the result is the same - significantly reduced cycle times.
BOC Edwards 6" superblower series are compatible with any make or type of vacuum pumping system. The boosters can be mounted separately, or on the inlet of the backing pump. The latter forms a compact integrated package as a mechanical booster system. For even lower-pressure applications, two 6" superblower series can be used in series with one backing pump. This results in a significantly lower-cost and space-saving pumping
system.
Bypass technology is available in the 615 model to enhance your productivity further, while also assuring consistent, reproducible vacuum processing. The bypass valve limits the maximum differential pressure, enabling the booster to start from atmosphere and provide increased pumping capacity over the full pressure range. Eliminating the electrical pressure switch insures continuous, booster operation regardless of vacuum level.
The 1 11/16 inch extra large shaft diameter engineered into the 6" superblower range provides the capability for use with higher powered motors, in addition to ensuring a uniquely rugged and durable mechanical booster. The use of higher powered motors in conjunction with the high differential specification, allows the pumps to operate at their full displacement from atmospheric pressure, with appropriately sized backing pump.The 612MB offers these advantages in a standard package (see page 2-43). The 6" superblower is also available in a process isolation series (five mechanical seals) for optimum protection from dust and particulate contamination in arduous duty applications.

All mechanical vacuum boosters must be backed by a primary vacuum pump designed to discharge to atmospheric pressure. Below is a list of commonly used backing pumps:
• Dry Pump (GV Drystar or Chemical Drystar)
• Liquid Ring Pump (Two-stage LR Series)
• Oil Sealed Pumps (RV, EM or EVC)
• Piston Pumps (Microvac Series)
Features & benefits
