HiPace 30 With a pumping speed of 32 liters per second, the HiPace 30 is said to currently be the most powerful turbopump of this size on the market. Due to the small footprint and low vibration level, the pump is particularly suited for integrating in compact analysis systems such as portable mass spectrometers, small electron microscopes, and leak detectors. HiPace 300 H Pfeiffer Vacuum says the HiPace 300 H is the most powerful compression turbopump currently available in the pumping speed class of 300 l/s. With a compression ratio of 107 for hydrogen, it is suitable for generating high and ultra-high vacuum. Due to the high compression ratio, a low residual gas spectrum is created in the chamber, which is desirable for mass spectrometry applications, for example. Diaphragm pumps for HiPace turbopumps Since the HiPace turbopumps are equipped with a 24 V DC power supply, the diaphragm pumps of the MVP DC series are said to be the ideal backing pumps. The brushless DC motor allows adjustments of the speed to the specific needs of a particular application. In the automatic boost mode, the pump runs at full speed and reduces once a certain vacuum is reached. In this way, high performance, long maintenance intervals, and low noise and vibration levels are achieved.
