Vertical Slurry Pump vs. Submersible Pump: How to Tell Them Apart
Two pump names cause more confusion on industrial sites than they should: the vertical slurry pump and the submersible pump. They sound alike, they are both vertical, and they both move abrasive, solids-heavy slurry. The difference lies in how far each one sits in the liquid and what that does to the motor and the mounting. This piece covers what each pump is, where they differ in practice, and how to pick the one that fits your pit or process.

The vertical motor sits on a support frame above the liquid and drives the pump shaft through a coupling, so the power train stays dry. The benefit of that layout is how little t...
