Attwood WaterBuster 4140-4 Portable Submersible Utility Pump, 200 GPH Battery-Operated Cordless

The Attwood WaterBuster (part number 4140-4) is a cordless, battery-operated portable pump built to remove unwanted water quickly and safely, without the hazard of an electrical cord in a wet environment. Powered by three D-size alkaline batteries, it runs for up to 5 hours per set and moves up to 200 gallons of water per hour on open flow, or 125 gallons per hour against a 2-foot head. It can lift water to a height of 40 inches. The pump ships with a 42-inch drainage hose fitted with a garden hose adapter, so a longer hose can be attached when extra reach is needed.

Its compact 5.25-inch diameter and 6.5-inch height let it fit into tight spaces such as bilges, kayaks, and small hatches, while its fully submersible plastic housing stands up to repeated wet use. Typical applications include draining kayaks, inflatables, duck boats, dinghies, and paddle boats that lack a hard-wired electrical system, as well as clearing water from pool covers, aquariums, and sump pits. The WaterBuster is intended for portable, on-demand water removal only and is not designed to be installed as a permanent bilge pump.
