Multistage Centrifugal Pumps

Multistage horizontal and vertical high pressure pumps in segmental type design with many variants for clean and slightly polluted liquids.


Main applications of the multistage pumps are booster systems, irrigation systems, boiler feed and condensate systems, washing plants, filter technique, water treatment and hardening systems. By means of auxiliary NPSH- stages NPSH-values up to 0,5 m are being achieved.

 

Multistage pumps amde by EDUR pump factory.

EDUR pump factory produces multistage centrifugal pumps.
