APIC-1231 - Single cartridge stationary seal with outboard Labyrinth seal for Plan 31 on API610 & API682 pumps

The APIC-1231 is a single cartridge mechanical seal with integral vortex breakers in the gland plate and external high-end labrinth, which offers superioe performance over a r-bush in high pressure washdown applications. The seal is designed in compliance with API682 seal specification, as employed in the Oil & gas sector, but can be adapted for older API610 Ed.7 pumps, where required.

The innovative stationary seal design is offered as a complete cartridge mechanical seal solution and is designed for API Plan31 arrangements on API610 V8 onwards process pumps.

Design Features include;

• Flush orifice for Plan 31 systems. Important: The flush orifice does not 'shot blast' the stationary seal face when used with process liquids containing suspended particles.
• Quench and Drain orifices for Plan 62 or 52. Steam/buffer fluid is directed to the inboard faces via an integral deflector built into the seal gland.
• Large Seal port orifices - Flush 1/2" NPT, Quench and Drain 3/8" NPT
• Gland plate with integral vortex breakers
• Radial clearances between rotary and stationary components conforming to the best practice requirements of API682.
• Monolithic seal faces for improved high temperature performance
• Stationary seal design with self-aligning stationary seal face. ideal for high speed applications,
• Multi-spring design with springs out of the process fluid.
• Outboard Stanseals parrallel OD labyrinth seal; for superior egress and ingress performance, specifically in high pressure equipment washdown applications.
• Can be used in conjunction with the Stanseals Plan 31 Cyclone Separator system and Sample collection pot.
