Allweiler Series SRZS Side Channel Pump

The Allweiler SRZS Series is a side channel pump with a baseplate-mounted design, developed for demanding applications up to PN 40. Thanks to its side channel pumping principle, the SRZS series is particularly well suited for handling gas-containing liquids, volatile liquids, liquefied gases, and refrigerants, where conventional centrifugal pumps may struggle due to vapor formation or gas entrainment.

The combination of excellent suction characteristics, self-priming capability, and high-pressure performance makes the SRZS a reliable solution for industrial, refrigeration, and process applications.
