Lubi Pump Seal

Fewer Leaks and Longer Run Time on Lubi Pumps

On a pump that runs every day, a worn seal means leakage, wet bearings and a stopped line. Most early failures come from dry running, dirty water, or a seal that does not match the original size. Our Lubi pump seal is made to the original fitting dimensions, so it goes into the existing pump without any modification. Fitting is simple. Clean the shaft, seat the stationary ring squarely in its housing, slide the rotary unit to the correct working length, and refit the impeller. The carbon rotary face is paired with a hard Silicon Carbide stationary seat. This pairing handles slightly dirty water and mild chemicals, runs cooler, and keeps leakage low over long running hours. The result is longer seal life and fewer pump breakdowns. Share your pump model and shaft size with us and we will confirm the right seal before you order.
