Pfeiffer Vacuum has introduced high-compression models with its new HiPace 700 H turbopumps.
The turbopumps have a compression ratio of ≥ 2.107 for hydrogen, the pumps are suitable for generating high and ultra-high vacuum. Due to the high compression ratio, a low residual gas spectrum is created in the chamber.
The HiPace 700 H turbopumps have a high critical backing pressure capability of 22 hPa, allowing the pumps to reach ultra-high vacuum, even when operating with high backing pressures that occur in combination with diaphragm pumps.
“With the new HiPace H-family, we have the ideal turbopumps for research and analytics applications as well as for other industrial applications. In terms of energy efficiency as well, this product is far ahead,” said Florian Henss, Product Manager at Pfeiffer Vacuum.
“Due to the integrated ‘intermittent mode’ function, the HiPace H switches a connected backing pump on only if the backing pressure is no longer sufficient. This reduces the energy consumption of the entire vacuum system by up to 90%,” Henss continued.
Due to the hybrid bearing, combining a ceramic ball bearing on the fore-vacuum side with a permanent-magnet radial bearing, the turbopumps are equipped with a robust bearing concept, resulting in a long service life with a service interval of more than four years.
