Among these are the EU machinerydirective, GMP Rules and Regulations, FDA Regulations,3A sanitary standard, EU Foodstuff HygienicGuidelines, DIN EN 12462 Biotechnology, the recommendationsof the EHEDG (European Hygienic EquipmentDesign Group) and QHD (Qualified HygienicDesign).Shaft sealsDepending on the application and pumped liquid, singleor double mechanical shaft seal arrangements areavailable to ensure trouble-free operation.Double seal arrangements are offered as either atandem or back-to-back seal arrangement.The single shaft seals used are inboard mechanicalseals with an optimum position in the pumped liquid inorder to ensure lubrication, cooling as well as CIP(Cleaning-In-Place) and SIP (Sterilisation-In-Place).Standard seals have seal faces of carbon/stainlesssteel and O-rings of EPDM. Other seal face materialcombinations are available on request.ConnectionsA variety of connections are available. These includesterile threads to DIN 11864-1 PN 16 and sterileflanges to DIN 11864-2 PN 16.Other connections such as SMS, RJT, DIN or ISOclamp connections and Tri-Clover are available onrequest.Special sterile threaded fittings and flanges can also besupplied.3
