With the air-cooled, oil-free SCROLLVAC plus, Leybold offers an uncomplicated, reliable
backing pump. Its properties predestine it for a wide range of demanding applications, such as laboratory vacuum furnaces.
The HiPace 300 H also has an integrated "intermittent operation" function which switches on a
backing pump only when the backing pressure is no longer sufficient.
ULVAC released the HELIOT 900 series leak detectors in June 2014 with
backing pump up to 250/300 (50 Hz/60 Hz) L/min).
For example, in vacuum packaging situations, production and packing speeds will decline due to reduced air flow through the pump, with poorer end pressure and interaction between the
backing pump and booster arrangements that are so often used in such applications.
The overall long-term maintenance on the system was greatly reduced versus the mass spectrometer vacuum system because the Falcon Leak Test System does not have a vacuum chamber, a chamber vacuum pump, a mass spectrometer instrument, or a
backing pump for the mass spectrometer.
The SSTC utilizes an oilless diaphragm roughing or
backing pump and an oilless turbomolecular high vacuum pump.
Their functional and design features simplify daily use of the
backing pump. For example, the hermetic sealing of the rotating parts from the pump chamber reduces the risk of contamination.
ULVAC launches the ceramic ball bearing turbo molecular pump, UTM300B, in addition to the existing line-up, small size pivot bearing type, medium and large size magnetic levitation turbo molecular pumps, to meet to the requirements such as free mounting orientation, more compact design, smaller size
backing pump, etc in the trend of diversified applications of turbo molecular pumps.
