CDR introduces model XTN and XTS: a cutting-edge solution designed for liquid with suspended solids.
A few years ago, one of the most important CDR customer issued a challenge: to create a pump able to withstand the presence of solids, suitable for heavy duty processes, safe and reliable enough to avoid clogging or breakages typical of centrifugal pumps with mechanical seals, and minimize production stops.
Starting from these inputs CDR developed an innovative magnetic drive pump that it is able to handle fluids with a certain content of suspended solids. Made it in a short time and tested directly on the working site, the mag driven pump achieved in less than a year outstanding results: no emission and no production stops, without any mechanical seal or external flushing: a real revolution!
Currently the solution seen on the market are using an external filter installed on the pump outlet. The suspended solids are thus blocked by the filter, that avoid the contact of the particles
with the bushings. Before introducing this revolutionary pump series, CDR proposed a work-around, installing a double mechanical seal –on the UCL series- combined with the external flushing barrel: this allows enough reliability, and zero emissions during the fluid transfer.
Anyway the weak point of this solution may be revealed in case of mechanical seal’s failure: in this case the leakage of the barrier fluid contaminate the processed liquid and all the mixed solution has to be irremediably scrapped out, a very onerous task in term of time and money.
But how do they work?
With these new pumps, CDR has completely overcome the critical points above mentioned. The main operating principle of the XTN and XTS pump is to facilitate the free circulation of suspended solids. All internal passages between rotating and the static parts have been designed in a way that no solid particles can block the recirculating flow.
CDR designed completely open NEW IMPELLERS, that guarantee the circulation of liquid without any clogging. Also the impeller’s shape drastically reduces the axial thrusts, normally present with closed impellers.
For the first time an impeller of this type is installed on a magnetic drive pump: it is made as a single piece in PFA material lined on a steel frame, without any welding point or gaskets.
NEW BUSHES have been also specifically designed with generous canals to facilitate the
free circulation of solids. The pure silicon carbide brings excellent mechanical and chemical resistance. The diamond-like-carbon surface treatment also guarantees an excellent resistance against dry running, by reducing up to 90% the friction generated between rotating and static bushings.
XTN and XTS pumps have been realized with these innovative solutions to ensure process safety and the reliability, even in case of liquids with suspended solids.
A real revolution for the magnetic driven pumps, now realized by CDR in two
Types: PFA version (XTN) and in SS316 version (XTS).

We are delighted to announce that CDR Pumps has been shortlisted as a finalist for the Chemicals Northwest Supplier to the Chemical Industry Award 2026.
Being shortlisted is a fantastic recognition of the work our team does every day to support the UK chemical industry with innovative, reliable and safety-focused pumping solutions….
A long-term customer, who operates within the chemical manufacturing industry, approached us because they needed to modernise and improve control over their tanker unloading processes. Their existing systems operated by either using the “blowing method” or relying on pumps mounted on the tankers and weren’t particularly reliable, consistent, or safe, especially when it comes to handling aggressive chemicals such as 96% Sulphuric Acid and 50% Hydrogen Peroxide.
Chemical pumps improve the performance of your fume scrubbers!
It’s a bold statement, but true. Industrial ventilation plays a key role in workplace safety and regulatory compliance in manufacturing plants. Industries like chemical processing, pharmaceutical manufacturing, and metalworking rely on robust (and reliable) ventilation systems to remove harmful fumes, particulates,…
