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.
