Double impeller life with run dry safety!

For generators and main engine cooling pumps.

The average failure time of a dry-running impeller is around two and a half minutes, so frequently an impeller is destroyed before an alarm goes off! Normally the impeller rubs against a static brass cover plate with sea water as lubricant, hence a rapid failure when running dry.

Speedseal Life solves this by using the award winning High Slip Bearing with a PTFE disc placed between the end of the cover recess and the rotating disc which is in contact with the impeller. When the bearing discs become worn, they are simply replaced at low cost without the need to replace the cover plate.

Prolonged and repeated run dry tests.

The UK's Yanmar importers have carried out tests on the bearings used in Speedseal Life and achieved 10 consecutive tests on 10 minutes dry-running without failure.
