ercem SEALS ERCEM Operating principles: 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 115mm 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. Concerning stainless steel rings for shaft above Ø55mm, they are composed of two parties to facilitate mounting.

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

ercem SEALS BELLOW ERCEM can be fitted with two different types of bellows : - First one, simple bellows are made an elastomer and of is particularly used for recreational with shaft diameters up to 41.275mm (1’’ 5/8). - Second one, reinforced bellows are made of high strength reinforced nitrile covered by Aramid more known as Kevlar®. It can be mounted on our entire range. Its advantages are increased resistance to petrochemicals products, UV, cuts, strains and also to high temperatures. WATER PICK UP KITS Water Pick-Up Kits include everything needed to connect your ERCEM to a point in the...

ASSEMBLY INSTRUCTION STANDARD ERCEM SHAFT Ø <55mm OPERATING PrINCIPLE ERCEM is composed of an elastomer simple or reinforced Kevlar bellow (2) which is mounted on the sterntube (10) with 2 hose clamps (1). A graphite ring (3) is mounted on the other side of the bellow with two hose clamps. The stainless steel ring (5), fastened to the shaft by 3 grub screws (4) compress the graphite ring thereby sealing between these two parts. Sealing between the stainless steel ring (5) and the propeller shaft is formed by two O-rings (7). PRECAUTIONS Mounting of the ERCEM and any maintenance...

ASSEMBLY INSTRUCTION Tighten the two clamps (1) sterntube (10) side on the cuff of the bellow (2) (tightening torque 10 Nm). Place the stainless steel ring (5) gently on the propeller shaft with the O-rings (7) mounted, polished face on the graphite ring side. To facilitate installation, use soapy water. Do not lubricate the shaft with oil or grease. Bring the stainless steel ring (5) in contact with the graphite ring (3) without applying a compression on the bellow. Mark this position on the shaft with a marker just in front of the stainless steel ring to identify the neutral position (no...

ASSEMBLY INSTRUCTION TROUBLESHOOTING Premature wear of the graphite ring with strong projections: Check the compression of the bellow and adjust if necessary Check the surface condition of the contact surfaces of graphite and stainless steel rings, clean the stainless steel ring with a clean cloth or replace parts as necessary. Check and control the flow rate and the water supply pressure in the graphite ring. The maximum pressure allowed by the ERCEM seals is 0.7 bar. Leak at rest: Check the surface condition of the contact surfaces of graphite and stainless steel rings, clean the...
