A Submersible Drainage Pump is a type of centrifugal pump designed to operate fully submerged in the fluid it is pumping. These pumps are typically used to remove unwanted water or other fluids from construction sites, basements, tunnels, mines, or industrial processes.

  • Electric motor sealed in a watertight housing

  • Impeller for moving water or fluid

  • Pump casing (usually corrosion- and abrasion-resistant)

  • Built-in cooling system (uses the pumped liquid for motor cooling)

  • Float switch or level sensor (optional, for automatic operation)
