Stainless Steel Stern Shaft Seal Device

1. Range of shaft diameter:110mm~350mm. 2. Leaking volume:< 20 drops/min. 3. High water seal performance

1. Product FeaturesStrong anti-abrasion ability is achieved by using special hard alloy as the material for static and dynamic sealing rings, so that shaft runs without abrasion. No grease is required. Abrasion compensation on the sealing rings is made automatically by axial spring resistance, so that tight sealing is guaranteed. Maintenance of the device can be done offshore, which saves lots of time and efforts and increases utilization of the ship. Anti-corrosion materials are being used for all parts of the product, so that its life span is long

Listed in this table are structural data for standard design. Structure of the device can be customized according to user requirements.

3. Technical Data 1. Range of shaft diameter: Φ110mm~Φ350mm.2. Leaking volume: ≤20 drops/min.3. Working temperature (surface): ≤65°C.4. Life span: same as ship. 4. Model Selection1. Size of the seal is determined by parameters like shaft diameter and structure of the place of installation. If the shaft comes with shaft liner, size of the seal will be determined by diameter of the shaft liner.2. Enough operation space should be allocated for maintenance engineer during design and model selection.3. Customized design can be done according to user requirements, such as size, structure and interface.5.
