Description

Slurry Pump Mechanical seal is widely used in chemical slurries, alumina plant, FGD systems, power plant ash handling systems, pulp and paper and other industries. The mechanical seal consists of a stationary and a rotating face pressed together under mechanical and hydraulic pressure to prevent leakage. Silicon carbide is the most common material used for manufacture of these seal faces. The use of mechanical seals in slurry applications requires extreme care and attention due to the limited reliability common in this developing area. Sea costs are relatively high and require substantial justification to warrant their use.

The mechanical seal with no flushing is not suitable for all the conditions. It has very strict usage requirements:
a. the concentration of the slurry could not be too high. It is the best lower than 30%. It could work lower than 40%. If higher than 40%, it is not suggested.
b. the temperature of the slurry could not be too high. It could not higher than 80℃.
c. the particle size could not be too big, which is easy to disturb the mechanical seal work.
d. the slurry is better if it has no or a little crystal. The crystal will disturb the mechanical seal.
e. When slurry pump runs, the liquid should be full in the pump chamber.
