Pfeiffer Vacuum have introduced the HiPace 300 H, a high compression turbopump working at 300 L s–1, and with a compression ratio of 107 for hydrogen, making it suitable for high and ultra-high vacuum. It has a high backing pressure compatibility of 30 hPa, which helps the pump achieve ultra-high vacuum when operating with high backing pressure in combination with diaphragm pumps. An “intermittent operation” function switches on a backing pump only when the backing pressure is no longer sufficient; this lowers energy consumption of the entire vacuum system by up to 90%.
