Bearing Protection

The Inpro/Seal Company manufactures a Bearing Isolator that will provide the highest level of bearing protection available. Inpro/Seal® Bearing Isolators are made of high quality bronze and are designed to last for at least 100,000 hours compared to the common lip seals which usually fail after only 3,000 hours. With the latest engineering and manufacturing technology Inpro/Seal can meet your reliability requirements with seals designed specifically for your equipment with quick, timely deliveries.
This two-part dynamic seal consists of a stator press-fitted into the bearing housing and a rotor attached to the shaft. The rotor and stator form a non-contact, compound labyrinth, so there is nothing to wear out
It protects two ways:

  • Bearing lubricant is captured in the inner portion of the labyrinth and flows back to the bearing housing
  • Outside contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the stator by centrifugal force and gravity

At PUMPNSEAL we offer full seal refurbishment for all manufacturers. No matter the size or complexity, Inpro-Seal and PUMPNSEAL’S team can design a custom seal for your equipment.
