Expeller is also a very important slurry pump part. It can help to seal the pump, as well as to reduce the centrifugal force. The design and material of expeller is significant to its service life because it is also one of the wet parts. Slurry pump shaft seal is composed of expeller along with expeller ring, gland, shaft sleeve and other small parts. 

Standard shaft seal and Hi-seal are available for CNSME slurry pumps. For hi-sealed slurry pumps, the expeller and expeller ring used will have "HS1" in their part numbers. Hi-sealed slurry pumps will have relatively better sealing effects than standard shaft sealing type, and will bear bigger suction pressure. 

CNSME specialists will select the most suitable shaft seal methods for our customers.
