Tonkaflo Centrifugal Pumps

Durpro is proud to offer Tonkaflo pumps for use in a wide range of applications. Tonkaflo pumps originated back in 1977 because mass-production-oriented pump manufacturers weren't interested in developing high-pressure pumps for RO applications. Due to this, GE Osmonics developed the Tonkaflo line of pumps, with nearly 200 models to fit specific application requirements. Whether you need special chemical compatibility, quiet operation, or have value as a top priority, we have a Tonkaflo pump to fit the application.
