Kiwi Shaft Seal™

The design consists of a single piece stainless steel housing with a single lup seal configuration. This results in a NO maintenance, completely rebuild able and safe seal.

The Kiwi Shaft Seal™ carrier is manufactured from stainless steel, which is light weight and durable. The guide bush (Thordon) fitted into the carrier contains friction reducing additives for longer life and reduction of noise. This Thordon material has Lloyds, Bureau Veritas, ABS and Nippon Koiji Kyooki approvals.

The lup seal used in the Kiwi Shaft Seal™ assembly is a radial lup seal. With the advent of harder and higher grades in stainless steel, shaft wear is practically non-existent with the Kiwi Shaft Seal™ arrangement.

The Kiwi Shaft Seal™ design utilises straight reinforced hose since it does not require great flexibility to provide compression like a mechanical seal. The reinforced hose is fastened to the shaft seal carrier and the shaft log with the aid of stainless steel hose clamps.

The Kiwi Shaft Seal™ is cold water (salt or fresh) lubricated through a water feed line. A SS water feed fitting is drilled and tapped into the seal housing for security. A stainless steel ball valve and tails are supplied with every unit to regulate the water flow rates for the different seal sizes.

All Kiwi Shaft Seal™ are individually built and each unit has an engraved serial number that relates to the original customer history.
