HOME / PRODUCTS / MECHANICAL SEALS / SINGLE CARTRIDGE MECHANICAL SEALS / MECHANICAL SEAL STYLE ANSI FLEX
ANSI Flex Seal Line
Mechanical Seal Styles:
ARB3 (standard), ABRB3 (Big Bore), ASMS2 (standard),
& ABSMS3 (Big Bore)
The Versatile Standardised Solution for ANSI Pumps
Big Bore faces are designed with larger ODs for additional radial clearance and seal cooling
Both standard and big bore glands supplied with 3 connections to accommodate any piping plan
Set clip redesign for even easier seal installation
ARB3 (STANDARD BORE)
FEATURES:
Simple and solid single cartridge seal construction
No dynamic elastomers – the most common failure point with multi-spring pusher seal designs
Only one O-ring (especially economical if perfluoroelastomer required)
Stationary welded metal bellows designed for better alignment
Hydraulically balanced
Seal faces positioned near lantern ring connection for enhanced heat dissipation
Hastelloy® C276 bellows
SPECIFICATIONS:
Materials of Construction
Rotating Seal Face: Carbon, Tungsten carbide, Sintered silicon carbide
Stationary Seal face: Sintered silicon carbide
Bellows: Hastelloy® C276
Metallurgy: 316 SS
Elastomers: Viton®, Ethylene propylene, Aflas®, Buna, Neoprene, Perfluorelastomer
Gland Gasket: Glass-filled Teflon™
Throttle Bushing: Glass-filled Teflon™
Operating Conditions
Temp: 400F (200°C)
Pressure: 300 PSI (20 bar)
Speed: 4500 FPM
Note: Max Temperature / pressure / speed indicate operating extremes independently and do not imply the seal will function at these extremes at the same time. Contact Specialised Flow Solutions if in doubt.
ABRB3 (BIG BORE)
FEATURES:
Rotating design uses centrifugal force for self-cleaning
Uniform 360° transfer of torque to the rotating face
Welded metal bellows replace the dynamic elastomer which can hang up the seal faces
No springs to clog or break
No fretting
Only two (2) static elastomers – eliminate seal failures caused by dynamic O-ring “hang up” and offers cost savings when upgrading to Perfluorelastomers
Monolithic rotating seal ring made from a solid, homogenous material and is easily field-repairable

ASMS3 (STANDARD BORE)
FEATURES:
Stationary springs and drive pin mechanism isolated from process fluids to minimize corrosion, clogging, and stress-related failures
Unique, metal-shrouded rotary seal ring for maximum face protection and uniform 360° transfer of torque to the rotating face during start up
Dynamic elastomer moves on non-metallic, smooth surface eliminating fretting
Stationary design for optimal face alignment

FEATURES:
Stationary springs and drive pin mechanism isolated from process fluids to minimize corrosion, clogging, and stress-related failures
Unique, metal-shrouded rotary seal ring for maximum face protection and uniform 360° transfer of torque to the rotating face during start up
Dynamic elastomer moves on non-metallic, smooth surface eliminating fretting
Stationary design for optimal face alignment
Floating stationary seat design adjusts for misalignment and is cushioned from vibration, both of which improve face tracking
