Pumping power to move… a lot.
The Stanley SM20 is one of the lightest and most durable pumps available. Completely submersible and pumping 250 GPM at a 10 ft. head and moving solids up to 5/16 of an inch makes it ideal for vaults and manholes. It features a cast aluminium inlet and a steel impeller. Tool Weight: 18 Lbs. Flow Range: 4-9 GPM
The Stanley SM21 sump pump is ideal for small opening and confined spaces. It can remove more liquids than other pumps since the cast iron impeller is only 3/4 of an inch from the base. It can pump 300 gpm / 1125 lpm at a 50 foot head.
