EVOLUTION FOR US IS A NATURAL MATTER Many geniouses and luminaries, such as Leonardo Da Vinci, have spent their lives seeking perfection and reflecting it in their projects, through an intensive study of the divine proportion. Using the same philosophy, CDR also pursue the perfection without compromises in its products. This is the fundamental that connects our milestones, an EVOLUTION that has pushed us to overcome traditional systems, leading us to be among the pioneers of magnetic drive technology.

A step beyond... Thanks to the magnetic drive technology, the rotating motion is transmitted without any mechanical contact, simply by exploiting the attraction of the magnetic fields. Without any joint or sealing, it is achieved a complete liquid containment, eliminating risks of dangerous leakages: the safest system for the operator, as well the most respectful for the environment. EVOlution phase two: we are proud to make a further step beyond and introduce you the new UTS EVO.

UTS Bareshaft version “back pull out”. Baseplate installation couplings and coupling guards motor frame B3. The torque is transmitted from the shaft to the impeller thanks to the magnetic coupling: the external magnet (connected to the motor) drives the internal magnet (solid to the impeller), without any direct or physical contact. The transmission of the rotating motion to the impeller is ensured by just magnetic forces of attraction / repulsion between the two magnets. An isolation shell guarantees the complete isolation of the pumping liquid from the external environment. Evolution of the...

UTS-B Close-coupled version with standard motor frame B5, now also available with motor frame B35 New baseplate. New magnetic couplings: excellent performance even in case of pumping high viscous liquids. Ideal solution for handling toxic, flammable and dangerous liquids. Thanks to the internal ATEX certification, also suitable to handle non-conductive liquids.

Cast iron surfaces are protected by 3 paint layers (total 260 microns): RAL 5021 color (all colors available on request) Internal magnet: different magnet design guarantees improved performances with viscous liquids. Painting standard available: • Standard ISO 12944-5/C4.10 • On request ISO 12944-5 System: C4.11, C5.07, C5.08, CX (ISO 12944-9) Magnets can be in SmCo or NdFeBo according to the temperature of the pumped fluid. Different magnet lengths allow to optimize the power consumption. PT100 connection socket for temperature monitoring on the isolation shell. 3 An isolation shell in Hastelloy-C...

Construction Details Volute Casing Made in cast steel AISI 316, it ensure excellent corrosion resistance. Standard threaded drainage. Heating jacket available on request. Impeller Made in cast steel AISI 316 (1. 408), it 4 guarantees excellent and precise vanes profile design and corrosion resistance. The counter-vanes reduce the axial thrusts and, as consequence, the wear of the internal components.

The rotating shaft is mounted inside a SIC bush, supported by 2 static bushes: this configuration guarantees high reliability in continuous service, distributing correctly the axial and radial thrusts. Flanged bushes support, also available in a pre-assembled kit with bushes already installed, for a quick and safe maintenance. PTFE compensating rings guarantee high resistance to the impeller axial thrusts.

Minimum continuous stable flow (MCSF) Preferred operating region N J I TV { Diamond CoatedSIC bushes: In case of high risk of dry running, it is available on request a kit (shaft / bushes / axial thrusts) in diamond-coated SiC (RSSICtm). The surface treatment grants both hardness and a friction reduction of about 80% (0.04 prs of RSSiC versus 04 - 0.7 prs of SiC). Other critical working conditions on which RSSiC increases reliability and pump life-time are: • Pumping of low boiling liquids • Operation at low flow rates (near MCSF): the heat generated by the magnetic coupling (eddy current) is...

The redesign of the 3 magnetic couplings improve the efficiency, demanding less energy for the same duty. The Isolation shells are made by flow-forming, to avoid any internal material tension. The flow-breaking seat on the bottom of the isolation shell avoids the formation of liquid vortex inside the pump PT100 connection socket for temperature monitoring as a standard.

Zirconium oxide and 0n0rC|y saving. Advantages of the ZrO2 Isolation shell: • Reduction of absorbed power up to 25%, resulting in the increase in pump efficiency. In order to eliminate the eddy currents generated by the Hastelloy • Removal of the Joule effect caused by eddy currents. Isolation shell, a zirconium oxide ZrO2 isolation shell is available This is essential in all cases where pumping low-boiling fluids or liquids upon request subject to evaporation • Preservation and stability of the liquid temperature, in conditions where duty is close to the admissible minimum flow

Heating jacket arrangement JACKETED VOLUTE CASING JACKETED BUSHES SUPPORT In all cases where the medium tends to solidify, if pumped below its solidification point, pumps with heating jackets on casing and bushes support are available upon request, in order to have an homogeneous temperature all throughout the pump. In case of particularly critical fluids (see phthalic anhydride) it is also possible to heat the isolation shell as well.
