Inpro

Pumps, motors, and other rotating industrial equipment require effective and permanent bearing protection. Protecting bearings from premature failure is critical to the reliability of rotating equipment in industrial process industries. We are proud to be the exclusive distributor for the Inpro Seal Company in Western Australia and the Northern Territory. We stock a variety of common styles and sizes to respond quickly to your requests.

The Inpro/Seal Company manufactures a Bearing Isolator that will provide the highest level of bearing protection available. Inpro/SealŪ Bearing Isolators are made of high quality bronze and stainless steel 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:

  1. Bearing lubricant is captured in the inner portion of the labyrinth and flows back to the bearing housing
  2. 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

Inpro/Seal Bearing Isolators install easily on most shafts, even those that are already damaged. There's even a split seal for large shafts to simplify installation.

The Inpro/Seal Bearing Isolator is the industry standard for bearing protection and is now standard equipment on IEEE-841 motors manufactured by all the major motor manufacturers in the United States, Taiwan, Korea, Canada and Mexico.
