Spirax Sarco

Our Spirax Sarco steam specialties business is the global leader in the supply of engineered solutions for the design, maintenance and operation of efficient industrial and commercial steam systems.

As a heat source, steam is the natural choice in most industrial processes due to its high heat-carrying capacity, controllability, sterility and efficiency as a heat transfer fluid. With our specialist knowledge, technical expertise and wide range of products and services, as well as our extensive global presence, Spirax Sarco is uniquely positioned to provide a broad range of environmentally friendly engineered solutions to the many industries using steam.

Our customers face a variety of challenges including high energy costs, pressure to improve the operating efficiency and capacity of existing processes, and the need to comply with increasingly stringent health, safety and environmental legislation. Our direct sales force is highly trained in product application, system performance and the troubleshooting of steam systems.

The Spirax Sarco offering is very wide, from single products through to complete turnkey bespoke packages that can include design, fabrication, installation, commissioning and maintenance.



Watson-Marlow is the global leader in peristaltic and selective niche pumps and systems, specialising not only in the design and manufacture of the most advanced pumps and tubing, but also in the application of those pumps to our customers’ processes.

Our peristaltic pumps are ideal for difficult pumping applications. They are highly accurate and controllable and virtually maintenance -free, making them a very reliable and cost-effective solution.

Operating a make-to-order manufacturing system and uniquely extruding our own pump tubing, we have the leading position in the supply of peristaltic pumps and tubing to the biotechnology, pharmaceutical, wastewater treatment, mining and food industries.

The peristaltic pumping market is a small part of the global pump market but it is one of the fastest growing segments.
