The PQD is a Double Acting Seal made of three sealing elements, the
dynamic seal is a ring in TRIALON® (fi lled PTFE) with the LOBE Ring in
TRIAFLEX® (NBR) at the centre, which results in low friction, while the
static seal is an O-Ring in TRIAFLEX®(NBR), also acting as an energizer.
Depending on the application, media, cycle speed etc., the PTFE compound
is selected and the O-Ring & Lobe Ring compound also can be
changed from the standard compounds, considering the media compatibility,
