3M launches sealless centrifugal pump

The centrifugal pumps from 3M can handle fluids with a maximum viscosity of 200 cSt at flows up to 90 mc/h and maximum system pressures up to 16 bar. The pumps feature an isolation shell which separates and seals the fluid chamber from the atmosphere. This makes them suitable for use with aggressive or high purity fluids in chemical and pharmaceutical applications.

The centrifugal pumps are also suitable for transferring acids, alkalis, hydrocarbons, heat transfer oils, liquid gases, toxic and explosive chemicals in industrial and chemical industries. They can pump low viscosity surfactants, acids and CIP chemicals in pharmaceutical and cosmetic industries.

In the food and drink industries, the pump are suitable for handling CIP chemicals, such as sodium hydroxide, nitric acid and hydrogen peroxide and pumping water treatment chemicals.
