Flowserve SIHI Application

The Sterling Flowserve SIHI CEHA pump is a self-priming side channel pump capable of
handling gas along with the medium and operates at a low noise level

Flowserve SIHI Design

The Sterling Flowserve SIHI pumps of the series CEHA have a segmental type construction
with open van wheel impellers. This combination pump is suited with a centrifugal stage
in serial connection before the side channel stages to obtain a more favourable NPSH
