Busch Vacuum Solutions USA, a Virginia Beach, Va.-based manufacturer of vacuum pumps, blowers, compressors and systems, acquired Jennings Associates Inc., a distributor for new equipment, maintenance and repair for vacuum pumps, blowers and heat exchangers. The acquisition of Jennings’ vacuum pump, blower and service portion of the business furthers Busch’s long-term goal of providing better technical and service support for customers in the eastern central region of the United States. 

The HiPace 350 and 450 turbopumps are dedicated for applications like mass spectrometry, electron microscopy, metrology tools, particle accelerators and plasma physics.

The COBRA NX 0950 A PLUS is a dry, oil-free vacuum pump that can run with pressure control or at a constant rotational speed, making it exceptionally energy-efficient.

Busch Vacuum Solutions collaborated with the European Space Agency, Fluid Gravity Engineering Ltd. and the University of Glasgow to prepare a space mission for the Mars rover Perseverance. The craft started its mission to Mars weeks ago and will hopefully bring back rock samples for future research. Vacuum pumps from Busch are part of a system that studies the behavior of a rocket when it lands on the surface of Mars or the Moon. With the help of the vacuum pumps, the landing of a rocket is simulated, and the surface of Mars and the Moon is imitated on the basis of different pressure levels.

Hena 50 and 70 are single-stage, oil-sealed rotary vane pumps specially developed for the demanding requirements of mass spectrometer systems. They achieve pumping speeds of between 32 and 59 m³/h, depending on their size and speed of rotation.

The TURBOVAC i/iX series of turbomolecular pumps are used where clean and stable high- and ultrahigh-vacuum is required, such as in heat treatment.

Two new online tools have been developed to assist customer’s pump choice and layout of complete vacuum systems: The Pump Finder and calculation tool LEYCALC.

Many papers have been written on the subject of vacuum furnace leaks, how to detect them and how to find them.

The overall furnace design and volume determines the required throughput of the pumping system and the ultimate vacuum expected.

The DRYVAC DV 200 and DV 300 complement the existing product range of DRYVAC 450, 650 and 1200 and offer the same user benefits for applications requiring smaller sizes.
