The Stanley SM21 Hydraulic Submersible Water Pump is one of the lightest and most durable pumps available. It’s capability of pumping 300 gpm (1135 lpm) at a 50 foot head make it ideal for vaults, manholes and more specifically in confined narrow openings. The SM20 will out-pump most all gasoline engine driven pumps. There is no recoil starting, priming or suction hose as with gas engine driven pumps. It can be run dry without damage.
The cast iron impeller of the SM21 is within 3/4 of an inch of the base allowing the pump to remove more liquids than other pumps. With only a few moving parts, the SM21 is virtually maintenance free.
