BUSCH Dry Screw Vacuum Pumps COBRA BA COBRA BA are proven dry screw vacuum pumps perfectly suited for demanding processes such as sterilization, metallurgy, gas recovery or furnace applications.
COBRA BA are proven dry screw vacuum pumps perfectly suited for demanding processes such as sterilization, metallurgy, gas recovery or furnace applications.
The patented self-balancing screw design ensures lowest vibration levels and quiet operation.
COBRA BA vacuum pumps feature a bell-shaped cantilever construction: The twin rotor with variable pitch screws is mounted only on the motor side. Thanks to the unique “flying bearing” design, inlet bearings are unnecessary. Therefore, the pumped medium does not come in contact with the bearings. This ensures clean vacuum generation and allows to fully recover the pumped medium.
COBRA BA vacuum pumps are characterized by an efficient air cooling.
A directly mounted, canned motor makes the dimensions of the COBRA BA series very compact.
