Centrifugal pumps
Centrifugal pump ZA

Centrifugal pump ZA - standard priming
With this type of pump open or semi-open impellers are used.
The ZA centrifugal pump can be used to convey fluid media with viscosities up to 500 mPas without any danger of clogging.

- Performance range
- Application area
- Execution
- Even waste water from textile processing plants, which contains fibres and threads, can be pumped without difficulty by SAWA’s ZA pumps.
- Many applications in the membrane filtration and reverse osmosis industry have confirmed the suitability of the ZA pumps.
- Special execution for cosmetics, pharmaceutical and sterile industries.
- CIP and SIP.
- Swiss Made: robust design of high-grade stainless Cr-Ni steel 1.4435 (316L).
- All wetted parts are electropolished.
