Slurry Pump Expeller Ring


Expeller Ring

The expeller ring is one of the main components composed of the centrifugal seal of the slurry pump, and the centrifugal seal is the most commonly used shaft seal type on the slurry pump. However, centrifugal seals also have limitations.
All centrifugal seals have a limited number of inlet heads, which can be sealed relative to the running pump head. First, the acceptable inlet head limit is set by the ratio of the propeller diameter to the main blade diameter of the impeller.
Depending on the design, most blades will be sealed, provided that the intake head does not exceed 10% of the working discharge head of a standard impeller.
