What Is a Long Shaft Vertical Sump Pump?
A long shaft vertical sump pump is a vertical pump with an extended shaft connecting the motor and the impeller. The pump bowl or wetted part is placed in the sump, while the motor stays above the liquid surface.
This design helps:
Prevent motor exposure to liquid
Handle deep sump conditions
Reduce floor space usage
Improve maintenance convenience
