AROCHEM II 6211

PRODUCT DESCRIPTION
Merkel Arochem II combination braid consists of aramide and
PTFE graphite compound yarn. The DIAPLEX® braiding makes
this packing especially stable. Merkel Arochem II is particularly
suitable for the sealing of plungers and low speed shafts. The graphite-filled PTFE yarn on the contact area has very good sliding properties and protects the plunger or shaft surface. The stable

braided aramide yarn at the packing edges protects against
gap extrusion and ensures a long service life. Merkel Arochem II is thus especially suitable for difficult sealing cases such
as bridging large gaps and with abrasive media. In high pressure plunger pumps in end ring installation with pretensioned
packing sets especially long service life with constant sealing
effect is achieved.
