The SAWA WFI pumps made of stainless steel (1.4435) are generally manufactured in the pharmaceutical version. They therefore meet the highest standards of hygiene and process reliability. Robust, quiet and energy-efficient, they guarantee water quality in compliance with standards during the production of water for injection (WFI), also containing ozone. When pumping media containing ozone, the correct choice of material for the mechanical seal is decisive for process reliability. Thanks to a design without dead space, the pumps can be cleaned very easily and quickly and then sterilized.
