FDS - Double Screw Pump
Dual-purpose, twin-screw technology, refined, and perfected
In the pursuit of pushing boundaries in twin-screw technology, the development of the Fristam FDS Pump came to fruition. The approach involved a ground-up reassessment of functional principles in eliminating the commonly known deficiencies associated with this type of technology. Aspects such as smooth operation, temperature stability, maintenance, and repair underwent rigorous refinement until perfected. As a result, this unique product, attentively refined to the minutest detail, is now available.

Specific Construction
The Fristam FDS combines all the advantages of twin-screw technology with our company’s traditionally high-quality standards. This positive displacement pump is ideal for the most viscous products whilst also being capable of reaching higher speeds of up to 3,600 min–1. 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 and easily copes with high differential pressures without overheating.

Seals
Mechanical Seals
The FDS’ mechanical seals are fully immersed in the flowing medium. Their smart layout ensures improved protection from leakages with both single- and double-acting seals. The semi-cartridge principle, in combination with the clever design of the pump casing in three segments, make mounting and replacing seals simpler than ever. If needed, they can be removed and loaded through the front with just a few quick and easy steps.
Casing
Sophisticated Casing
The three-piece pump casing of the Fristam FDS consists of an intermediate flange, the screw casing and the pump cover. This layout allows previously unimaginable flexibility when it comes to connection types and individual adaptation to system requirements. Furthermore, it is specifically configured for easy access and maintenance. The FDS offers maximum efficiency with extremely tight internal clearances.
Flexibility
Maximum Flexibility
With its wide range of feed screws featuring various pitches, the Fristam FDS offers maximum flexibility. This pump is suitable for a great range of applications and capable of meeting the most diverse requirements as well as the highest standards. Furthermore, its well thought-through design opens up previously unimagined freedom with many possibilites for mounting as well as easy access and maintenance.
Shaft
Especially Solid Shaft
When constructing the shaft, we specifically focused on adding strength in the area of its critical diameter. This ensures maximum rigidity even under the most difficult conditions and results in an especially smooth run, along with lower operating temperatures also under elevated pressure. Ultimately, it expands the FDS’ lifespan significantly.
Gearbox
Sophisticated Gearbox
When designing the gearbox, we put a special emphasis on creating a smart yet hands-on layout. Access to the synchromesh gear is facilitated through a cover that can be removed easily with just a few turns of a screw. The pump can be kept in its position, and even moving the drive becomes unnecessary. Thanks to its specially designed bearings, the FDS offers previously unimagined simplicity with regard to all gear-related maintenance procedures.
