High precision and quality mechanical shaft seal made of combined 316 Stainless Steel and Graphite, easy to install and upkeep.
The mechanical seal takes place thanks to the perfect junction between the Stainless Steel ring and the Graphite part. The Stainless Steel ring is mounted with headless screws on the shaft (thus it rotates with it), while the Graphite part remains stopped on the shaft seal. The mechanical shaft seals can be mounted directly on sterntube with the Rubber sleeve fixed with clamps. The Rubber sleeve sterntube standard attach size is 87 mm, but by using reductions the mechanical seal can be mounted even on sterntubes of 70 mm or of 2”1/2 and 3”.

It can be completed with wall mount Bronze shaft seal adapter complete with water lubricated bearing (see codes 4900635<>4900680).
