MECHANICAL SEALS for SHIPBUILDING
Mechanical Seal MMS
Solution for boats with axles from 100 to 300 mm.
The MMS mechanical seal is equipped with multiple springs that guarantee a uniform load, adapts to vibrations and axis deviations. For the MMS seal the replacement of the parts subject to wear, in case of emergency, can be done without removing the shaft, using the semi-split component spare kit.
The seal can be supplied with the optional IDROSTOP flange, the safety device which, once inflated, blocks the entry of water from the through-hull. The IDROSTOP allows extraordinary maintenance interventions in case of accidental leakage of the seal without having to dry the boat.
| DIAMETER | SPEED | PRESSURE | TEMPERATURE |
|---|---|---|---|
| 100 – 300 (mm) | 0 – 10 (m / sec) | 0 – 5 (bar g) | -5 to 80 (° C) |
Features
- Optional pneumatic safety system “Idrostop”.
- Connection for lubrication and cooling
- Balanced stationary ring to reduce power absorption.
- Rotating ring in wear-resistant material for greater abrasion resistance.
- Self-aligning drive ring.
- Mobile positioners for easy and correct assembly.
- Body of the seal in marine brass for greater safety and resistance.
- Springs in AISI 316 to tolerate vibrations and axial deviations.
- Gaskets in fireproof material.
Mechanical Seal MUV-MUSV
Solution for propeller shaft from 40 up to 125 mm.
The MUV and MUSV (split version) models can be installed no shafts from 40 mm up to 125 mm; in this cases the seal ring of the stationary element is in special graphite (Z31) and that of the rotating element is in chrome molybdenum steel (V1) or silicon carbide (U41).
On request seals can be certified by any of the major maritime institutions.
