The LSR Cleanout Pump combines several unique design features that make it an excellent pump for your pond and waterfall cleanouts. The fast 3,744 GPH (14,173 LPH) flow rate and the capability to pump down to 3/16" (4.75 mm) make quick work of removing the water. A rubber pump casing protects the pump and the pond liner while the screened pump intake strainer keeps fish and frogs safe during the cleanout process.
