Slurry is defined as solids in liquid. Their size and quantity are not important. You must be careful when introducing cooling to this type of seal because the unit does not rotate, causing an uneven cooling of the lapped face. In recent years this seal has only been available in cartridge designs adding to the misalignment problem and increasing the initial cost considerably. The inside mounted seal.
All components are in the pumping fluid.
The elastomer can move to a clean surface as the seal face wears. Centrifugal force throws solids away from the seal components allowing the lapped seal faces to stay in co Disadvantage. All the metal components must be corrosion resistant to the pumping fluid. If the product solidifies or crystallizes when the pump is stopped, the seal can become inoperable. The outside mounted seal.
