The Fristam FDS combines all the advantages of double-screw technology with high quality standards. It is suitable for a wide range of applications and offers maximum flexibility. This very special positive displacement pump is ideal for the most viscous products. At the same time, it is capable of reaching higher speeds of up to 3,600 RPM. Consequently, it can transport significant amounts of any low-viscosity medium, for example water or detergent solution. This renders the use of an additional pump for cleaning processes obsolete.

The Fristam FDS can handle extreme viscosities as well as the highest loads effortlessly and easily copes with high differential pressures without overheating. Its axial transportation principle results in very low pulsation even in the highest pressure ranges. In addition, the FDS ensures superior hygiene as its mechanical seals are positioned in fully flushed areas with constant pressure conditions. Because there are no cavities, there is no residue when flushing the pump in CIP. Our latest pump is not only fully hygienic, but can also be sterilized.
