Wa+ Series - Aseptic Centrifugal Pumps

Aseptic version of the W+ Pump with double seal barrier fluid at all connections.

Environmental requirements are getting strict. But today, aseptic production is already essential to certain processes - including the manufacture of long life food and pharmaceutical products. The Wa+ pump is the perfect solution. All seals, including the shaft seal, are designed as double seals.

Double mechanical shaft seals fitted for sterile flushing
Double O-ring sealing of pump housing fitted for sterile flushing
Special aseptic fittings fitted for sterile flushing

Wa+ pumps ensure absolutely aseptic production processes with barrier media up to 150°C (320°F). With a Wa+ pump, the risk of contaminating the product and environment is thus reduced to an absolute minimum. Wa+ pumps are 3-A (optional) and EHEDG (European Hygienic Engineering & Design Group) certified.
