Dayton 26KJ18 O-Ring Kit T51 Mechanical Seal

Shaft Seal Kit for 7/8-Inch Turbine Pumps

This Dayton 26KJ18 kit provides a T51 mechanical seal and O-rings for 7/8-inch shaft diameters. It is compatible with Dayton turbine pump series and uses Buna-N, carbon and ceramic components. Maintenance teams can use it to restore sealing performance on supported equipment. The kit suits industrial facilities running compatible Dayton turbine pumps.

Mechanical Seal Limits in Abrasive Media

The T51 mechanical seal relies on carbon-ceramic faces and Buna-N elastomers. These materials resist typical turbine fluids but degrade faster with abrasive particles or aggressive chemicals. High shaft run-out or vibration shortens face life beyond normal wear. The kit does not address pump housing wear or bearing clearance issues.

Verify Pump Series and Shaft Diameter First

Confirm the pump carries the Dayton series name and the shaft measures 7/8 inch before ordering. Cross-reference the T51 designation with the original equipment manual. The kit includes O-rings, seal, seat and gasket only; it does not supply bearings, sleeves or hardware. Ensure the fluid type is compatible with Buna-N, carbon and ceramic materials.
