HydroMax Seal – SPW131
HydroMax Seal – SPW131
Compact Single Cartridge Mechanical Seal for API Plan 31 Systems
The SPW131 from HydroMax Seal is a single-cartridge mechanical seal engineered for space-constrained applications and compliant with API610 Edition 5 onwards. Specifically designed for API Plan 31 piping arrangements, it offers robust sealing performance when handling process fluids containing suspended particles or solids.
This cartridge seal integrates vortex breakers within the gland plate, reducing turbulence and protecting the stationary face in slurry-rich or particle-laden systems.
Product Description
Design Features
- Flush orifice optimized for Plan 31 systems — engineered to avoid abrasive impact on the stationary seal face when handling particulate-containing flush liquids
- Large ½″ NPT seal port orifices for improved flushing and system compatibility
- Gland plate with integrated vortex breakers to manage flow and reduce erosion risks
