1 STN Plastic Magnetic Drive Centrifugal Pups STN 40 PP-GF Copact, Plastic and Fluoroplastic Magnetic drive Horizontal - Single Stage - Centrifugal pups PP-GF (Polypropylene-Glass filled) - CFR-ETFE (Carbon filled - Ethylene tetrafluoroethylene) Close-coupled execution Coply to : 006/4/CE Available upon request : ATEX 100 Directive 014/34/EC Flanges : UNI 109 PN16RF type B ANSI 150RF R

2 R STN Mag drive concept The synchronous drive configuration is based on an outer agnet ring assebly built to agnetically couple with an inner agnet ring assebly. STN STANDARD EXECUTION with Motor Versatility The STN offer a wide range of aterials for the wetted parts : PP-GF (Polypropylene-Glass filled) CFR-ETFE (Carbon filled - Ethylene tetrafluoroethylene) - *only casing These two agnet rings are locked together by the flux of attracting agnet poles flowing through the containent isolation shell. STN ATEX EXECUTION without Motor Design Reliability Suitable for handling corrosive, aggressive and hazardous liquids (low viscosity, clean or slightly containated) in the cheical applications. Made with a reliable quality as the ETN but designed for saller applications or where the working condition are less critical. Application Fields Basic cheical Low Duty Service Waste Water Treatent Air Treatent C.I.P. Galvanic Industry

3 3D VIEW Inner and Outer agnets are equipped with rare earth peranent agnets. High cheical resistance eploying a perforing aterial as CFR-ETFE. Patented cage agnet attachent guarantees stability during the operation of the pup. Alternative available aterials for the Wetted parts: PP. The casing s design is reinforced by a solid rib structure. The STN are available in close coupled execution, suitable to be coupled with standard electrical otors. Sealless design Total containent, essential for hazardous, aggressive or valuable product.

4 R features CASING IMPELLER ASSEMBLY Available in CFR-ETFE and PP-GF execution The integral design of the ipeller and inner agnet prevents any isalignent proble, also reducing Standard casing drain for a coplete and fast draining of the casing the production cost Standard back vanes reduce axial thrust and seal chaber pressures to guarantee an extraordinary bearing and seal life. ISOLATION SHELL ETFE Non-etallic double Isolation Shell configuration on wet side, externally reinforced by a Polycarbonate can As alternative, it is available ade by a solid 3 PP-GF layer SHAFT Axial and radial loads are well distributed thanks to the highly reliable rotating parts design. The static shaft (SiC or Ceraic) is supported in the can and by the lining suction cover. Zero Eddy Current Losses thanks to non-etallic execution
