Rotary Seals

Walkersele M9

This fluoroelastomer (FKM) material and method of construction are suitable for Walkerseles operating in high temperature environments, or where fluoroelastomer is needed to accommodate high surface speeds or chemical compatibility. Walkersele M9 suits housings fitted with retaining plates.

Media compatibility
Excellent resistance to all lubricating oils, fuels, air, water and dilute acids.

Seal construction
Flexible back of fluoroelastomer-proofed aramid/glass fabric, with lip of fluoroelastomer.

Maximum under-lip temperature
200°C constant: but note that under-lip temperature can often be substantially higher (eg, by 30°C) than fluid media temperature.  

Maximum surface speeds
25 m/s with Walkersele D6 and D8 designs.
20 m/s with Walkersele D7 design.
