SIHImulti Pump MSC

The SIHImulti Pump MSC range of horizontal, ring-section multistage pumps have been designed for long-term reliability when pumping high-pressure liquids. The design features within this range of high-pressure pumps, provide our customers with unique solutions to long-term concerns about power consumption, efficiency, and reliability. A special feature is the wide range of speed, which is ideally suited for frequency inverted running. Meeting the technical requirements of ISO 5199 / EN25199, they have a modular concept in order to reduce the number of parts, and consequently our customers’ inventory. Premium levels of efficiency are available by selecting an appropriate set of impellers and diffusers that give an ideal fit to the process requirement. Unique to the multi-stage arena portfolio is the SIHI, patented self-adjusting drum style of axial thrust balancing. The MSC employ a device that reduces the bypass flow to an absolute minimum, while not being susceptible to long(er) term wear-sensitive clearances.
