PDH
PDH and PDP, catagorized as slide ring seals, are
designated to fit as standard sealing elements where normal piston seals are
actually applied. Characteristics include keeping the same groove dimensions
while offering two material combinations. The PDH, composed of Acetal resin
back-up rings (protecting the dynamic sealing part from extrusion and
preventing dust particles to reach the seal), a main sealing element in
reinforced PTFE (giving excellent support to all earth moving equipment
where high pressure and speeds are present) and a NBR energizer which
statically seals the PDH in the housing groove. The second version, or PDP,
is an excellent economic alternative composed of Acetal resin back-up rings,
a main sealing element in Polyurethane Tecnolan (guaranteeing
longer service life, resistance to wear, and easier installation) suitable
for agriculture machinery where low pressure and moderate velocity occurs..
