The SPW131 is a single cartridge mechanical seal with integral vortex breakers in the gland plate design to fit small x-sectional spaces, typically in accordance with API610 Ed.5 onwards.

The seal design is offered as a complete cartridge mechanical seal solution and is designed for API Plan31 arrangements, with process fluids containing suspended particles and solids.

Design Features include;

• Flush orifice for Plan 31. Important: The flush orifice does not "shot-blast" the stationary seal face, if the flush liquid contains particles/soilds.
• Large Seal port orifices - 1/2" NPT.
• Gland plate with integral vortex breakers
• Compact single stationary cartridge seal design - short inboard and outboard lengths.
• Designed to fit into small x-sectional seal chambers.
• Multi-spring design, with springs out of the process media.
• Hydraulic and pressure balance seal face technology for optimum performance.
• Monolithic seal faces for improved high temperature performance
• Used in conjunction with the Reliability seals Plan 31 Cyclone Separator system and Sample collection pot.
