Magnum-P V6S

The Magnum-P V6S bearing isolator is the result of our dedicated mission to increase bearing life. It utilizes magnetically controlled lapped flat sealing faces in collaboration with expulsion ports. Isomag's primary sealing surface rotates with the shaft, and does not damage shaft surfaces! The MP V6S creates a positive, bi-directional seal with or without shaft rotation, on horizontal or vertical applications. Bolted flange designs are per customer specification. It can be used in thousands of applications from 3/4" to 20" shaft sizes. Our compact design interchanges with common labyrinth isolators. The problem of lubricant loss and bearing contamination are resolved, helping achieve and improve maintenance cycle life expectations.
