1 1 EEX gerotor pump unit For use in oil circulation systems in gas- and dust-ex-atmospheres

2 Gerotor pump series 1 EEX The 1 EEX product series has been specifically designed for centralized lubrication systems in explosive environments. It offers a high degree of protection in a gas or dust explosive atmosphere. The 1 EEX series is a complete pumping unit solution including pump, motor, coupling and sealing all according to ATEX requirements. It is based on the well-proven and established SKF 1 gerotor pump series. It feeds the lubricating oil from a reservoir into the pipe system of an oil lubrication system. The 1 EEX is a self-priming positivedisplacement pump with high efficiency and one delivery circuit. The annular-toothed feeding element, also referred to as the gerotor, is equipped with a cycloid contour, which creates a large tooth meshing length. This yields a low volumetric flow pulsation and thus very smooth running, low noise production, and good suction characteristics. Features and benefits: Reliable and safe operation in explosive environments (Zone 1,, 1, ) Low volumetric flow pulsation allows very smooth running Gerotor with a cycloid contour provides optimum suction characteristics Low noises during operation Large viscosity range for standard mineral and synthetic lubricating and hydraulic oils Compact design with pump, motor, coupling and seal Durable and rugged gerotor pump unit Explosion protection: ATEX ATEX II G c IIC T Gb ATEX II D c IIIC T10 C Db IECEx (motor only) Ex de IIC T Gb Ex tb IIIC T10 C Db Further information Brochure PUB 110 Assembly instructions You can download the publications as PDF file from the SKF website skf.com/1 Online configurable under skf-lubrication.partcommunity.com Table 1 Typical layout of an oil-circulation system Technical data Lubricant standard mineral, synthetic lubricating and hydraulic oils Viscosity mm /s Flow range 0,8 0 l/min 0. 1 gal/min Operating pressure up to 0 bar up to psi Operating temperature 0 to +0 C + to F Lubricant temperature 0 to +0 C + to 10 F Protection class IP Drive speed depending on design 1 00 and 800 r/min Suction head, max. 00 mm Varnishing Duty type per VDE Sealing material Mounting position ATEX classification for gas ATEX classification for dust Materials Pump housing Gerotor insert Shafts Bearing RAL 0 graphite grey, special painting optional 00 S1 FKM horizontal, vertical II G c IIC T Gb II D c IIIC T10 C Db hydraulic cast (pressure-proof) with good wear and antifriction properties sintered material low-deformation case-hardened steels SKF plain bearing Flow limiter EEX pump Oil reservoir

7 SKF CircOil EEX systems Reliable operation in challenging environments SKF CircOil systems circulate oil to lubricate and cool bearings in many industrial applications. They also eficiently remove dirt, water and air particles. This cooling effect becomes especially important in explosive atmospheres. Friction, wear and contamination can lead to overheating and bearing failures. This creates a potential ignition source and risk zone. SKF offers a range of CircOil EEX pumps, metering devices such as the SKF flow limiters and systems that help to ensure reliable safety in your operations. All products were designed to provide a high degree of safety in gas- and dust-ex-atmospheres. Application areas with explosive gas or dust: Oil and gas industry Energy generation Chemical and pharmaceutical industries Food and beverage Agriculture Wastewater Marine Heavy industry Machine tool industry Wood industry SKF CircOil EEX Benefits: Safe operation in explosive environments Efficient cooling and lubrication Increased machine reliability and reduced downtime Many customizable solutions available Demand-based distribution of lubricant Efficient visual and electronic monitoring options Prolonged oil life thanks to patented air-removal design Reduced oil purchasing, handling and disposal costs 1 EEX ATEX code II G c IIC T Gb European Explosion Protection Mark ATEX Equipment group II = Non-mining Equipment category G = High protection for gas zones 1 and D = High protection for dust zones 1 and Protection method c = constructional safety (EN1-) Gas / Dust group IIC = all gases like Methane, Propane, Hydrogen, Ethylene IIIC = all dust and flyings Temperature class T = maximum surface temperature 1 C T10 C = maximum surface temperature 10 C Example: II D c IIIC T10 C Db Non-mining High protection for dust zones 1+ Constructional safety All dust and flyings Temperature 10 C High protection for zones 1 + Equipment Protection Level (EPL) Gb = High protection for gas zones 1 and Db = High protection for dust zones 1 and
