BJM Pumps has a fantastic little utility pump for areas where conventional line power is not available. The Baby is available in a manual or automatic configuration.
The Baby is a 12-volt battery operated submersible pump that delivers up to 1,500 GPH, or up to 23 feet of head, yet weighs only 8 lbs. Perfect for emptying pipe trenches, bailing out a boat, or pumping down a flooded basement. Its non-metallic construction makes it suitable for salt water.
