Side channel pumps ZS_SRZS series


The ZS_SRZS side channel centrifugal pumps are multicellular self-priming side channel pumps with low NPSH. This range of pumps allows conveying liquids containing gas and has a centrifugal booster impeller.

This pump combines the advantages of a centrifugal pump with a side channel pump.

This pump technology has the advantage of combining low NPSH values and self-priming qualities (including with biphasic mixes), along with the advantage of not stalling in the event of cavitation.
