Inpro/Seal® Bearing Protection

Home > Products > Inpro/Seal® 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.

Technical Data on Bearing Isolator of a InPro/Seal VBX-D.


A well-known technique for increasing pump reliability is sealing the bearing housing with noncontacting bearing isolators rather than contact seals. Because contact seals use contact as their sealing method, they have a more limited life expectancy

Maximise pump life with bearing protection

Pumps are vital to the industrial process and designed to operate for many years, yet they consistently come out of service due to product leakage from mechanical seal failure. Mechanical seals can fail as a result of axial movement and shaft deflection caused by bearing damage
