CDR pumps for fibre production

Applications

The artificial and synthetic fibres account for 60% of the textile fibres used worldwide. Artificial fibres are produced from renewable raw materials similar to those used for natural fibres, while synthetic fibres are derived from polymers obtained through chemical synthesis. These large-scale production facilities operate continuously and feature vertically integrated processes, using traditional polymerisation technologies and advanced methods to transform the polymer into fibre, which can take the form of either staple fibre or filament yarn.

Centrifugal pumps used in fibre production processes include the UTS and ETS, both made of steel and known for their high strength. The UTS is a high-efficiency single-stage centrifugal pump, available in both close-coupled (UTS-B) and bare shaft (UTS) versions. These magnetically driven pumps, made of AISI 316 stainless steel, are designed for continuous operation (24/7). In synthetic fibre production, the UTS is widely used in thermoregulation processes. The magnets can be Neodymium Iron Boron or Samarium Cobalt, depending on the temperature of the liquid being pumped. The Hastelloy-C 276 containment shell offers excellent corrosion resistance and minimizes thermal loss caused by eddy currents. The UTS bare shaft version is installed on a baseplate, with a coupling and shroud for mounting with B3 form motors. This pump can handle fluids within a wide temperature range, from -100°C to +300°C.

The ETS is another magnetic drive centrifugal pump, also made of investment-cast AISI 316 steel, known for its high resistance to corrosion. The Hastelloy-C 276 containment shell reduces eddy current losses. Available in a close-coupled version, the ETS is suitable for B5 form motors and is ideal for all applications requiring the use of steel pumps for compatibility reasons.

Finally, the XTS is a metal magnetic drive centrifugal pump, specifically designed for pumping liquids containing suspended solids. Built using innovative technologies, the XTS is designed to optimize performance, safety, and reliability in basic chemical processes.
