Busch (UK) has announced a new addition to its Cobra range of screw vacuum pumps, designed for use in a wide variety of applications. The Cobra NC 400 B is robust in construction and reliable in operation, while at the same time being energy efficient for the user. Featuring an asymmetrical screw profile and free gas outlet, the new Cobra provides improved ability to handle liquid and dust carry over. The optimised efficiency of the pump reduces thermal load, which in turn maximises the service life of the installation. Uniform temperature distribution gives high resistance to corrosion.
Cobra NC 250 B has ATEX certification projected for category 1 and 2 and fast access screws allow for easy servicing. Other key features include a vacuum capability of between 1 hPa (mbar) and atmosphere.
