Magnum-P V7

The Magnum-P V7 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 and a deep channel labyrinth. Isomag's primary sealing surface rotates with the shaft, and does not damage shaft surfaces! The MP V7 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.
