FSI Shear Pump: Pump and Blender in One

Fristam’s FSI Series Shear Pump is an impeller-style version of the Fristam FS Series Shear Blender.

Pump and Blender in One
For applications requiring both pumping and mixing, Fristam’s FSI has an integrated impeller that provides high flow rates while still mixing your product.

The FSI can also replace a pump and blender combination in many other processes, including finish/supplemental mixing.

Designed with a front-loading seal, the FSI allows production personnel to service the pump in place.
