Our pumps are used in a wide range of chemical metering applications to help chemical vendors deliver:
Qdos® chemical metering pumps reliably handle challenging substances including:
Simplifying chemical feed and ongoing support is critical to maintaining reliable processes, especially when rapid response to changing conditions is required.
Qdos pumps reduce complexity for end users as they do not require high-maintenance ancillary parts to function, which diaphragm and progressive cavity pumps often do. With a single, no tools component replacement, Qdos maintenance takes only minutes, keeping operations running smoothly.

"Our technical department was looking for a solution for dosing chemical reagents... We decided that the Qdos pumps and their peristaltic technology were the right solution. We fit them into our cases without reinventing the solution each time."
The simplicity and ease of installing, operating and maintaining Qdos make it a reliable chemical dosing solution that minimises operational downtime while ensuring processes are treated effectively.
Like Qdos, our Bredel hose pumps have no impellers, liners, mechanical or packed seals, check valves, rotors, or stators to replace. Their only wear part is the hose or tube, which is replaced in minutes with standard tools.
Qdos, Bredel and Watson-Marlow close-coupled and cased drive pumps have been proved to run without maintenance for longer periods than other dosing pumps.

Our pumps enhance operation safety due to their fully contained design. Enclosed pumpheads, hoses and tubing prevent chemical leaks and protect surrounding areas. This is particularly critical when dosing polymers, where spills are hazardous, expensive and timeāconsuming to clean up. The Qdos ReNu PU pumphead is specifically designed for safer, clean and leakāfree polymer dosing.
Qdos pumps support operator and environmental safety through:

"Our pumps provide peace of mind because, in the event of a failure, repairs can be carried out quickly, easily and much more safely than with diaphragm and valve pump technologies"
Chemical vendors can help to protect their customers from reputational damage through safer, more accurate and compliant chemical handling.
That is why increasing numbers of chemical vendors trust our peristaltic technology, application expertise and rapid-response support. With local support and guidance on specific applications, we ensure that chemical vendors deliver a predictable and efficient service for their customers.
The benefits of Qdos pumps are easy to notice when feeding viscous, abrasive and off-gassing chemical while its precise, adjustable control provides rapid response to process variations. Tool-free maintenance and quick pumphead replacement further maximise uptime and reduce the support burden.

"Using the Qdos pump allowed us to stabilise additive dosing, improve grinding and increase production. In addition, maintenance is minimal, and operation is much simpler."
With over 60 years of leadership in peristaltic pump technology and broad process knowledge across multiple industries, we provide chemical vendors and end users with confidence in their dosing solutions.
Our pumps give end users peace of mind, avoiding the frequent attention and downtime often required with alternative pump technologies.
Optional accessories further enhance process protection and reliability:
In addition to Qdos, our broad product portfolio allows chemical vendors to specify fitāforāpurpose solutions across a wide range of applications, while maintaining consistency across their installed base:
