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. 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.
