SPW682-131 High-Performance Single Cartridge Seal for Pumps

Design Features

• Flush orifice for Plan 31 – provides controlled fluid flow that avoids “shot blasting” the seal face when handling solids
• Quench and Drain orifices for Plan 62 or 52 – steam or buffer fluid is guided to the inboard face by an integrated deflector in the gland
• Large 1/2″ NPT seal port connections for efficient flow control
• Gland plate with integrated vortex breakers – ensures controlled turbulence and reduces solids recirculation
• API682-compliant radial clearances between rotary and stationary elements
• Monolithic seal faces enhance high-temperature reliability
• Stationary seal design with self-aligning stationary face – supports high-speed operation
• Multi-spring configuration with springs located out of the process fluid
• Dual outboard restriction bush design – segmented + floating bush combo for superior leakage control and pressure stability
• Compatible with the HydroMax Plan 31 Cyclone Separator System and the Sample Collection Pot
