About Sump, Water-Removal, Condensate, and Submersible Pumps

Compact Water-Removal Pumps

Also known as bilge pumps, these remove fresh and salt water from spots where other pumps don’t fit. They have an internal sensor, so they turn on when they detect water and turn off when the water is removed. Pumps are fully submersible. They are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry.

Pumps for 12 volts DC work with 12-volt batteries.

Pumps for 120 volts AC and pumps with an acetal housing are for use in debris-free water.
