Watson-Marlow Pumps Group - Watson-Marlow Pumps Group

Watson-Marlow has grown rapidly to lead the world market for peristaltic pumps and positive displacement pumps. The peristaltic principle enables sensitive, abrasive or corrosive fluids to be pumped safely, accurately and without contamination anywhere from biotechnology to ceramics and food processing to waste treatment. 

The Watson-Marlow Pumps Group encompasses six manufacturing businesses: 

• Watson-Marlow Pumps- delivers the high-performance peristaltic tube pumps for the pharmaceutical and industrial sectors
• Watson-Marlow Tubing- produces precision tubing, including platinum-cured silicone tubing: Pumpsil; and TPE materials: Bioprene and Marprene
• Bredel Hose Pumps- manufactures heavy-duty hose pumps
• Watson-Marlow OEM- provides unique peristaltic solutions to OEM customers
• Flexicon Liquid Filling - specialises in peristaltic aseptic filling and capping systems for pharmaceutical, biotech and diagnostic applications
• MasoSine Process Pumps- manufactures, gentle, sinusoidal rotary pumps for food and pharmaceuticals

 We are a wholly-owned subsidiary of the Spirax-Sarco Group.

Watson-Marlow Tubing leads the world in Pumpsil, Accusil, PureWeld and Bioprene TPE pump tubing specifically manufactured for the biopharmaceutical industries. In their state-of-the-art cleanrooms Watson-Marlow manufacture Pumpsil premium quality platinum-cured silicone tube, Bioprene a unique Thermoplastic Elastomer (TPE) tube and PureWeld XL a pure thermoplastic elastomer that can be welded and heat-sealed. Watson-Marlow also produces tubing for food, industrial and mining applications. They are the only peristaltic pump manufacturer who make their own precision tubing, providing custom sizes and packaging.

The MasoSine Process Pumps Positive Displacement Pump is a highly reliable pump for sanitary and industrial applications. It is frequently chosen as a food pump and is also used to transfer shear sensitive fluids such as shampoos and lotions for the cosmetics industry. The exclusive single shaft and single sinusoidal rotor are the centre pieces of an innovative, simple design. The sinusoidal rotor overcomes the limitations of conventional rotary lobe pumps to produce:  

• Low shear  
• Superior suction  
• Low pulsation 
• Gentle handling
• Simple, economical maintenance

Bredel Hose Pumps produce high flow high pressure pumps up to 80,000 litres/hour with pressures to 16bar (232 psi) with unique patented direct coupled design. Duplex and CIP models are available. These pumps are found in a range of applications including use as slurry pumps and for handling abrasive, corrosive, high viscosity and shear sensitive products.

Watson-Marlow Qdos pumps are designed as a chemical metering pump with flow rates up to 30 litres/hour at 7 bar (100psi), for use in environmental applications, including water treatment, and reagent dosing in the mining industries. This no-valve metering pump lowers installation and maintenance costs. As metering pump manufacturers they have created a drop-in replacement to diaphragm metering pumps.
