DOUBLE SCREW PUMP
Process flexibility – 3 pumps in 1: Reducing costs, simplifying the process, standardising factory lines. Where multistage processes are concerned, handling a wide variety of different products as well as CIP lines is common. Ordinarily multiple product pumps would tackle each application individually and additional CIP pumps were required for cleaning. However, with an FDS, this can be a thing of the past…
Due to its design, an FDS double screw pump, is equally capable of switching between:
1) Pumping multiple different products 2) Scavenging product – where maximising yield is important 3) Pumping CIP
With such a wide envelope of capabilities, a single FDS can be capable of replacing multiple pumps! Learn more about this here.
The ultimate problem-solving pump. The Fristam FDS double screw pump is offered for a wide variety of applications, but it can really prove its worth when combatting these particularly challenging applications:
Maintenance has never been simpler. Thanks to its compact size and specially designed bearings the Fristam FDS can be mounted horizontally as well as vertically. Inspection and maintenance have never been as simple as this: seals and conveying elements can be exchanged easily and quickly.
Optional extras which ensure the FDS can handle applications with even the most complex properties:

FDS Powerpack Designs – High Pressure Pumping For the highest-pressure applications, Fristam can supply an FDS power-pack option. This fabricated skid consisting of 2 FDS pumps stacked vertically above one another can withstand extreme pressures.
The Fristam FDS is EHEDG-certified and designed for ultra-hygienic applications. It features fully flushed mechanical seals and an open internal layout with no dead zones, allowing CIP and SIP fluids to reach all product-contact surfaces. This ensures complete cleaning between batches and compliance with strict hygienic requirements.
Yes, the Fristam FDS is fully CIP- and SIP-capable. Its design allows it to pump cleaning liquids at high speeds and thin viscosities, removing the need for separate CIP pumps. The open seal area and high-velocity CIP flow ensure residue-free cleaning.
Yes, the Fristam FDS handles viscosities up to 1 million cP. Its strong axial screw design pulls thick products without cavitation or pulsation, making it ideal for applications like mayonnaise, fruit purée, or meat suspensions.
The FDS is self-priming and can handle up to 70% air. Its twin-screw configuration allows it to maintain flow even with air pockets or gas slugs, making it ideal for applications involving foamy, aerated, or suction-sensitive products.
The Fristam FDS is made from 316L stainless steel with duplex shafts. Gasket options include FKM, EPDM, HNBR, and FFKM. The pump is built for durability and chemical resistance under harsh CIP/SIP and processing conditions.
The FDS series delivers flow rates from 0.5 m³/h to 500 m³/h and pressures up to 25 bar. This wide performance range makes it suitable for everything from low-volume dosing to high-throughput transfer lines in food, beverage, and pharmaceutical applications.
Yes, the FDS offers flexible installation, including horizontal, vertical, or side-mounted configurations. This adaptability simplifies retrofits and tight-space installations in hygienic process environments.
Maintenance is quick and straightforward with the FDS. It features front-loading semi-cartridge mechanical seals and a patented gearbox that’s accessible without removing the drive, minimising downtime and simplifying seal replacement.
Yes, the FDS safely transfers abrasive and shear-sensitive media. Its wide-pitch, contact-free screws gently convey soft particulates like cooked fruit or meat chunks without damage, and abrasive seal materials can be selected to match application needs.
Fristam offers tailored adaptations such as ATEX certification, heated jackets, mobile units, and high-pressure power packs. Screw geometry, port configurations, and gearbox ratios can also be customised for your process requirements.
