CDR Pompe introduces models XTN and XTS: a cutting-edge solution designed for liquid with suspended solids. In 2015, one of the most important CDR Pompe 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 cloggings or breakages tipical 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 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.
