Abstract
A vortex slurry pump is provided comprising a column having a drive end and a wet end; a cantilever pump shaft rotatably supported within the column, and a drive means operatively connected to the drive end of the pump shaft. A vortex impeller is mounted to the wet end of the pump shaft, the impeller being configured to operate submerged in a slurry. At least one bearing arrangement is disposed within the column to support the cantilever pump shaft. An expeller seal arrangement is disposed between the vortex impeller and the at least one bearing arrangement, the expeller seal arrangement being configured to generate a dynamic seal to prevent the slurry from entering the column and contacting the at least one bearing arrangement.

A vortex slurry pump, comprising:
- a column having a drive end and a wet end;
- a cantilever pump shaft rotatably supported within the column;
- a drive means operatively connected to the drive end of the pump shaft;
- a vortex impeller mounted to the wet end of the pump shaft, the impeller configured to operate submerged in a slurry;
- at least one bearing arrangement disposed within the column to support the cantilever pump shaft;
- and an expeller seal arrangement disposed between the vortex impeller and the at least one bearing arrangement, the expeller seal arrangement configured to generate a dynamic seal to prevent the slurry from entering the column and contacting the at least one bearing arrangement.
A vortex slurry pump, comprising:
- a bearing housing having a drive end and a wet end;
- a cantilever pump shaft rotatably supported within the bearing housing;
- a roller bearing disposed at the drive end of the bearing housing to support the pump shaft;
- a set of at least one angular contact ball bearing disposed at the wet end of the bearing housing to support the pump shaft;
- a vortex impeller mounted to the pump shaft at the wet end;
- and
- an expeller seal disposed along the pump shaft between the vortex impeller and the set of at least one angular contact ball bearing.
