LP - Custom Seal Designs

Machine downtime due to bearing failure is costly. By keeping lubrication in and contaminants out, Parker’s ProTech™ bearing isolators provide reliable, two-way sealing protection of rotating equipment for extended bearing life. 

Labyrinth sealing technology applied to high performance materials allows Parker’s ProTech LP Profile bearing isolator to operate far beyond shaft speed limits of standard radial lip seals and avoid shaft wear. 

Our non-contact design has virtually no torque consumption and therefore will not wear or groove shafts, and allows for non-lubricated dry runs. 

It also accommodates the greatest axial movement in the industry, reducing a major factor that causes labyrinth seal failure. 

We can custom engineer solutions to meet exacting specifications for either new or retrofit applications. 

When used to replace seals during planned or unplanned rebuilds, the LP Profile lowers shaft cost due to liberal specifications. 

Costs can also be eliminated on tooling charges due to the fact that ProTech is a precision-machined seal. 

Many LP's have a labyrinth design like our ProTech LS Profile. 

However, the LP designation may also refer to a stator-only design for niche applications.
