Fristam FDS Hygienic Twin Screw Pumps: Advanced Technology for Superior Performance

Fristam FDS Hygienic Twin Screw Pumps, proudly made in the USA, are an innovative solution designed to set new standards in twin screw pump technology. We’ve reimagined the technical and functional principles of this advanced pump from the ground up. After extensive refinement and optimization of every component, the result is a pump that eliminates the common drawbacks of traditional pump technology. Its smooth operation, stability, ease of maintenance, and enhanced reliability make it a game-changer in industries that require high performance, hygienic standards and efficiency.

What is the Fristam FDS Twin Screw Pump?
The Fristam FDS is a positive displacement pump designed specifically for handling both viscous and low-viscosity fluids with ease. This highly sophisticated pump utilizes the advanced principles of double-screw technology, offering flexibility and reliability across a wide range of applications. Engineered for precision and optimized to the highest standards, the FDS pump delivers exceptional performance while maintaining hygienic standards, reducing wear, and improving efficiency.

Where is the FDS Twin Screw Pump Used?
Fristam FDS Hygienic Twin Screw Pumps are perfect for a variety of industries that require fluid handling of both high and low-viscosity fluids. Its robust design and versatility make it suitable for applications in:

Food and Beverage: Ideal for transferring sauces, pastes, fruit cocktails, oils, syrups, caramels, and other viscous food products.
Dairy: Perfect for pumping milk and products with variegates like creams and yogurt.
Pharmaceuticals and Life Science: Used in the transport of sensitive materials such as proteins, immunoglobulins, blood and antibodies.
Cosmetics: Handles thick creams and lotions with ease.
Clean-in-Place (CIP) Systems: Efficient for pumping detergents, solvents, and other chemicals used in the cleaning process, eliminating the need for additional pumps in the system.

How Does the Fristam FDS Work?
The Fristam FDS operates on a unique axial transportation principle that uses two screws to gently move fluid through the pump, reducing pulsation even under high pressure. This results in smooth, continuous flow with minimal wear on both the pump and the fluid. The FDS can achieve speeds up to 3,600 RPM, making it capable of pumping large quantities of both high-viscosity products and low-viscosity liquids such as water or CIP solutions.

A key feature of the FDS is its ability to withstand high differential pressures without overheating, ensuring a longer operational life and minimizing deflection or rubbing in the wet end. The pump’s mechanical seals are positioned in fully flushed areas, ensuring superior hygiene with no cavities to trap residue. This makes the FDS ideal for clean and sterile environments, as it can be fully sterilized.

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.

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.

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.

Robust 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.

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.
