Welcome to Watson Marlow

Watson-Marlow is the world leader in solving fluid handling problems with peristaltic tube, hose pump and sinusoidal technology. We are the world's leading manufacturer of metering pumps, dosing pumps, peristaltic pumps and positive displacement pumps, and are one of the only companies who are also specialist silicone tubing suppliers. We also build and supply aseptic filling machines to our customers' exact requirements. Watson-Marlow provides solutions across the major processing sectors:

• Pharmaceutical and biotech
• Food and beverage
• Chemical
• Waste and water treatment
• Mining
• OEM
• Engineering
• Brewing
• Paints and pigments
• Ceramics
• Pulp and paper

Pumps for process:

Watson-Marlow peristaltic pumps have great advantages over other pump types such as gear pumps and diaphragm pumps because there are no impellers, vanes, lobes or valves to damage the product. This separation of fluid from the pump action ensures contamination-free pumping which is ideal for shear-sensitive fluids, viscous sludges or slurries as well as aggressive acids and caustics.

You will find Watson-Marlow pumps across many industries such as brewing, chemicals, pharmaceuticals, print and packaging, science and research and water and waste and other application areas.

The Watson-Marlow 100 to 800 series metering pumps and dosing pumps have flow rates from as small as 1 microlitre/minute to 4,000 litres/hour. Each series type is very flexible, with a choice of pumphead characteristics, different control options including PROFIBUS capability and, as we are a silicone tubing supplier, we have a variety of tubing types available.

This, along with Watson-Marlow's five-year warranty on all core products, provides unbeatable value for money over the life of the pump.

Watson-Marlow Bredel delivers the highest quality, high-pressure hose pumping capacity. No other industrial pumps offer the same simplicity, reliability and low maintenance features as Bredel hose pumps.

With operating pressures to 16 bar and flow rates to 80 cubic metres per hour, Bredel pumps successfully handle the toughest applications such as chemical metering, transfer of slurries and sludge, and abrasives such as ceramics and mine tailings, as well as corrosive media.

Customers benefit from more consistent hose pump performance and can benefit from up to 30 years service from their Bredel hose pump, providing an almost unbeatable low life-cost of the pump.

The Bredel pump hose is the only element that comes into contact with the fluid. There are no seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode and replace, lowering the cost of replacement components and reducing maintenance downtime..

Bredel also manufactures its own hoses to ensure perfect compression and consistent, reliable performance. The hoses are made from high-quality compounded rubbers, reinforced with four layers of braided nylon and finished by high-precision machining to ensure even occlusion for life.

Watson-Marlow's OEM engineering team can design a custom solution if a standard Watson-Marlow pump does not meet your exact requirements, whether it involves a simple modification or a completely new design concept.


Once the exact requirements are understood, a prototype is developed and extensively tested in our dedicated testing laboratory. When the final result is approved the Watson-Marlow OEM pump can be built-to-order to deliver on time, every time. This further reduces overheads by lessening the need for customers to carry stock.

Flexicon offers aseptic filling machines and capping systems for pharmaceutical, biotech and diagnostic applications. Designed for use in sterile environments, Flexicon aseptic filling machines offer a high degree of accuracy with documented precision.

The peristaltic principle used in Flexicon aseptic filling machines means that when the process is complete the tubing can be easily cleaned or disposed of, eliminating the possibility of contamination and ensuring a fast and efficient validation process.

Flexicon offers a range of products that can be adapted and expanded to accommodate growth, from stand-alone units for manual filling, through semi-automatic systems, to fully automated filling, stoppering and capping machines. The fully automated systems are customised to fit any glass vial, plastic bottle, test tube, eye dropper or non-self-standing microtube. Filling volumes range from 0.1ml to more than one litre.

Watson-Marlow MasoSine sinusoidal pumping technology is ideally suited to applications where extremely viscous or shear-sensitive fluids are to be pumped and the quality and consistency of the end-product is paramount.

MasoSine pumps benefit from extremely powerful suction capabilities and an exclusive single rotor design, which provides a smooth and consistent flow of product through the pump.

The gentle wave action of the sinusoidal rotor maintains product integrity from small batches to high volume applications, including highly viscous products, up to 90,000 litres/hour. Many different applications such as food, beverages, dairy, confectionery, cosmetics and pharmaceutical preparations benefit from less wastage, faster processing and simple, economical cleaning and maintenance.

Watson-Marlow provides process solutions such as chemical metering pumps, dosing pumps, slurry pumps, sump pumps, ink transfer pumps, acid pumps, and pumps for adhesives, as well as difficult pumping solutions for shear-sensitive, abrasive, corrosive and particle-laden fluids.

Peristaltic pumps have no valves, seals or glands to leak, clog or replace. The fluid touches only a, flexible tube or hose – it does not come into contact with the pump itself. Maintenance is confined to a tube or hose change, which takes minutes. Peristaltic pumps are reversible, self-priming and dry-running.

The Watson-Marlow Pumps Group encompasses Watson-Marlow Pumps, Watson-Marlow Tubing, Flexicon Liquid Filling, Bredel Hose Pumps, and Masosine Pumps.

We have sales offices in Australia, Belgium, Brazil, China, Denmark, France, Germany, Italy, Korea, Malaysia, the Netherlands, New Zealand, South Africa, Sweden, Switzerland, the UK and the USA, together with a worldwide network of distributors.
