 KIWI Seal is a New Zealand made shaft seal composed of marine grade
stainless steel carrier housing, bearing that contains friction reducing
additives for longer life and reduced noise. The lip seal used in the Kiwi Shaft Seal
assembly is a radial lip seal, with reinforced metal case and nitrile
rubber elastomer.
With Henleys Propellers vast experience in the industry it has developed
the maintenance free, easy to install KIWI shaft seal.
The
KIWI shaft seal has 2 years* or 1000 hours* warranty and this product is
certified by SGS M&I New Zealand a member of the SGS Group (Societe
Generale de Surveillance).
The
KIWI shaft seal is available from 1" to 4" shaft sizes in 1/4" increments.
In selecting a shaft seal the following
criteria shall be considered by order of importance:
-
Safety
-
Level of operation/maintenance
-
Long term wear and tear of the shaft seal
-
Price
-
Compact size
-
Initial installation requirements
-
Shaft wear
The new
stainless steel KIWI Seal is lubricated by cold water (salt or fresh)
through a water feed looped and vented above the waterline. The cold
water fed through the seal cools the assembly and acts as lubricant for
the bearing surface fitted at the end of the shaft seal carrier. It is
an accepted good engineering practice to have the water feed line looped
and vented above the water line.
The KIWI shaft seal must be fitted onto a
stern tube that has a forward bearing that will support the shaft
directly behind the seal.
The Kiwi Seal
standard sizes are as shown in this link.
