Description
The COBRA single stage, direct criven, dry vacuum pumps, with their unique rotary screws, are designed for difficult applications in the pharmaceutical and chemical processing industries. They require no intercoolers and offer greater efficiency and easier maintenance than other types of dry vacuum pumps. They will operate at any pressure from atmosphere down to ultimate pressure. For higher pumping speeds and lower ultimate pressures, Busch offers COBRA/booster systems along with many other custom designed vacuum systems.
