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~Φ550mm, and it can be customized. 2. Leaking volume (per 100mm in diameter, when water pressure is higher than or equal to 0.01Mpa): ≤8 L/h. 3. The requirement on precision of centering of the shaft is low during installation. 4. Life span: same as ship. 4. Model Selection 1. 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 should 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.
