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:
We are a wholly-owned subsidiary of the Spirax-Sarco Group.
Watson-Marlow Pumps peristaltic pumps are self-priming and have no seals, valves, diaphragms, glands or impellers. They have clear advantages when handling solids and abrasive chemicals. Conversely the gentle pumping action of these tube pumps ensures that shear sensitive products, and fluids containing small pieces, such as food ingredients, can be pumped without damage to the product.
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:
Flexicon Liquid Filling aseptic filling and capping systems for pharmaceutical, biotech and diagnostic applications offers a range of products from stand-alone units for hand filling, through semi-automatic systems, to fully automatic filling, stoppering and capping machines.
A peristaltic pump is well suited to aseptic processes, as it is a sealless pump with no valves or glands to leak, clog or replace. The process fluid touches only a tube – it does not come into contact with the pump itself. The tubing can be easily cleaned or replaced, eliminating contamination and ensuring a fast and efficient validation process.
Watson-Marlow Pumps Group is the world’s largest custom peristaltic pump source for OEM applications. Their OEM peristaltic pumps are available at flow rates ranging from microlitres per minute to 80,000 litres/hour and from one to 32 channels of flow. The range includes a mini peristaltic pump which is the smallest in the market.
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.
