Slurry Cartridge Seal 

Slurry is a challenging media to pump and seal due to abrasiveness and chemical composition of pumped media.
Where the Specific Gravity (SG) is high a double seal design is usually advised where a lower SG can usually be accommodated by a single seal design.
Double Slurry Seals use barrier or buffer fluid as required by the application or API plan and this is essential for performance.
This requires a support system to manage the barrier/buffer fluid.
