Speed Seal Life

Part #EM4L from Speed Seal

Extended impeller life for both generators and main engine pumps, with tests showing routine improvements of two to three times normal life. Prolonged and repeated run-dry tests gave results of 40 x 5 minutes dry starts (tests stopped) without damage whilst maintaining performance. Increased pump life and performance.

Speedseal Life also provides the benefits of the standard Speedseal versionto give quick and easy impeller access for safety and convenience.

The old cover is removed and a Speedseal Life fitted using the existing screw holes � no modifications are needed.

More about the new Speedseal Life version:
The illustration shows the cover cavity into which the bearing discs are fitted over a central bearing spigot to form the award winning TIBS Extra Slip. Bearing from KPM Marine, now used in their Military Endurance pump range and pumps for Royal National Lifeboat Institute - RNLI.

The success is based on the research and development which proved the outstanding benefits of a combination of Brass and PTFE bearing discs. This dramatically reduces the friction �hot spots� at the end of the impeller now known to be responsible for wear and impeller failure.
