Materials
 Seal face: Silicon carbide (Q1), Carbon
graphite resin impregnated (B), Tungsten
carbide (U2)
 Seat: Silicon carbide (Q1)
 Secondary seals: FKM (V), EPDM (E),
FFKM (K), Perflourocarbon rubber/PTFE
(U1)
 Springs: Hastelloy® C-4 (M)
 Metal parts: CrNiMo steel (G)

Features
 Single seal
 Available for standard (Cartex-ASPN) and big
bore (Cartex-ABPN) seal chambers
 Cartridge
 Balanced
 Independent of direction of rotation
 Single seals with flush (-ASPN, -ABPN) and with
quench combined with lip seal (-ASQN, -ABQN)
or throttle ring (-ASTN,-ABTN)

Advantages
 Ideal for use in ANSI process pumps
 Universal applicable for packings conversions,
retrofits or original equipment
 Seal for standardizations
 No dimensional modification of the seal chamber
necessary, small radial installation height
 No damage of the shaft by dynamically loaded ORing
 Extended service life
 Installation faults are avoided, costeffective
 No damage caused by dirt entered during
assembly
 Straightforward and easy installation due to preassembled unit (reduced downtimes)
