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

Single Cartridge Mechanical Seal - ANSIFLEX

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 Seals 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

ABSMS3 (BIG 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

  • Floating stationary seat design adjusts for misalignment and is cushioned from vibration, both of which improve face tracking
