Product Features
HIGH CRITICAL BACKING PRESSURES
allow the use of relatively small mechanical backing pumps.HIGH THROUGHPUT
very high throughput at operating pressures.FOR CONTAMINATED SYSTEMS
most useful in pumping contaminated systems and high loads of hydrogen, hence their use in metallurgical and chemical processes.BEST USE
the pumps are used in the 10⁻¹ to 10⁻⁴ mbar range where rotary pumps are at their limit and ordinary diffusion pumps exhibit instability.LARGE PUMPING SPEED
very large pumping speed at high operating pressures.
