Propeller shaft mechanical seal ERCEM GV

boat

ERCEM GV seal is a mechanical seal which operate thanks to the friction of the rotating stainless steel ring and static carbon ring. The nitrile bellows fixed to the stern tube with collars 316L provides compression between the steel ring and the carbon ring . The rotating seal ERCEM tolerate misalignment and provides a perfect axial sealing thanks to the two O-rings mounted in the stainless steel ring and radial by pressing the carbon and stainless steel ring . Our ERCEM sealing are mounted on propeller shaft but also on rudders . - The standard model without inlet manufactured , used and recognized for several decades . Availability: Any diameter of metric or imperial shaft 22 to 65mm Application: Sailing - Fishing - Passenger boats - fast boats ... CARBON/GRAPHITE RING Rings are produced with Isomolded, very fine grain, high strength, high density, isotropic graphite resin impregnated for high mechanical and sealing applications. This material may tolerate temperatures up to 200 ° Celsius. Rings are produced on CNC machines to ensure a glossy surface state on the contact face. Depending on the application, the carbon ring may be provided with polyamide fitting to provide better lubrication in water or air vent. We use a non-metallic material to avoid electrolytic phenomena. STAINLESS STEEL RING 316L stainless steel rings are machined on CNC machine to ensure a perfect surface condition and exacting tolerances. The rings are slipped onto the shaft and held in place by 3 setscrews cup end in stainless steel 316L. The rings are also equipped with two O-rings in nitrile to ensure a perfect seal.
