Stanley SM21 Sump Pump Submersible Pump [SM2151101]

The SM21 Sump Pump is one of the lightest and most durable pumps available and will out-pump almost 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.
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.

Features

• Increased Capacity: 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. 
• Durable: Stainless steel, steel, urethane, or cast iron impellers (model dependent).
• Run Dry: Able to run dry without damage.
• Ease of Use: Lifting eyes make placement easy. Submersed into the water and with its easy hookup to a power unit, the SM21 is instantly pumping. There is no recoil starting, priming or suction hose as with gas engine driven pumps. 
• Submersible: No priming is required
• Maintenance: With only a few moving parts, the SM21 is virtually maintenance free.
