The new HiPace 300 H turbopump (photo) is said to be the highest compression turbopump in the pumping speed class of 300 L/s currently on the market. With a compression ratio of 107 for hydrogen, it is suitable for producing high and ultra-high vacuum. The high compression ratio generates a low residual gas spectrum in the chamber, which is desirable for mass spectroscopy applications. The vacuum pump comes in a radiation-resistant version with external electronics as an option. With its sophisticated rotor design, the HiPace 300 H has a very high backing pressure compatibility of 30 hPa. This helps the pump achieve ultra-high vacuum when operating with high backing pressure in combination with diaphragm pumps. The HiPace 300 H also has an integrated “intermittent operation” function that switches on a backing pump only when the backing pressure is no longer sufficient. This lowers the energy consumption of the entire vacuum system by up to 90%, says the company. — Pfeiffer Vacuum GmbH, Asslar, Germany
