Pneumatic cylinders - Duncan Rogers

P1DCylinderDesign variants for P1D Standard, P1D Clean, P1D Flexible porting and P1D Tie-RodOperation with dry piston rodIn many applications, primarily in the foodstuffs industry, thecylinders are cleaned frequently. This means that the film ofgrease on the piston rod is washed off, which puts specialdemands on the materials and the design of the piston rodseal system (scraper ring and piston rod seal). A piston rodseal system specially designed for dry rod operation is availableas options for this type of application, for all bores of P1Dcylinders. The system has a specially designed L-shapedseal and the material is self-lubricating, high molecular weightplastics (HDPE) – the same system as in our previous P1Ccylinders, with proven function.P1D with metal scraper ringStandard scraper rings cannot be used in environments wherethe piston rod may be coated with resin, ice, cement, sugarcrystals, dough, etc., primarily in timber handling, refrigerated/chilledtransport, cement industry, chemicals and foodand drinks. Hard and dirty coatings damage the standardscraper rings and shorten their service life, introducing dirtinto the cylinder. A scraper ring has been specially designedfor applications of this kind, as an option for all diameters ofP1D-S, P1D-T and P1D-V cylinders. The scraper ring, whichrequires a hard-chromium plated piston rod, has a stainlesssteel carrier, a brass outer scraper ring and a nitrile rubberinner scraper ring.1506.05www.parker.com/euro_pneumatic
