Description

The Thordon TG100 is a mechanical tailshaft seal for vessels with shafts from 86 mm (3.375 in.) to 305 mm (12 in.), operating in clean or abrasive-laden water. It is offered here for coastal workboats. It has hard-wearing silicon carbide faces and bellows made from Thordon's proprietary elastomeric polymers.

Key features

Elastomeric bellows with unlimited shelf life
Bellows accept axial and radial shaft movement and compensate for misalignment
Emergency seal allows stand-alone operation, so the vessel can return to port without permanent damage to the seal
Wedge "lock" design keeps the rotary face square to the shaft
Hydraulically balanced to suit different drafts
Requires no periodic maintenance. A well-maintained seal should need no parts within a 5-year drydock interval
An extra water port allows dirt and abrasives that build up in the bellows to be flushed out
Bearings and seals can come from a single supplier
