Rotary Seals

Walkersele M5

This Walkersele material and method of construction are specified for Walkersele applications where butyl (IIR) rubber is required for chemical compatibility with fluid media. Walkersele M5 suits housings fitted with retaining plates.

Media compatibility
Resistant to silicone oils and greases, ozone, hot and cold water, acids, alkalis, salt solutions, alcohols and glycols. Must NOT be used with mineral-based oils or greases.

Seal construction
Flexible back of butyl-proofed fabric, with lip of 70 IRHD butyl.

Maximum under-lip temperature
120°C constant: but note that under-lip temperature can often be substantially higher (eg, by 30°C) than fluid media temperature.

Maximum surface speeds
5 m/s with Walkersele D6 and D7 designs.
