Double Case Submersible Pumps

Davey double case pumps are specialty submersible pumps that are designed to stay cool when not completely submerged. The double case allows water to flow fully around the pump motor, ensuring continual cooling and a longer pump life.

While primarily used as a fishpond pump, or other aquaculture applications, it can also be used for domestic waterfalls or fountains, emergency flood relief or sump emptying and water transfer.
