Stanley SM21 Submersible Pump 2-1/2″ Outlet

The Stanley SM21 submersible pump is the ideal pump for confined spaces and small openings. It can pump up to 1125 lpm with a 15m (50ft) head.

The Stanley SM21 hydraulically driven submersible pump is a small diameter (caisson style) self priming hydraulic dewatering pump with the ability to pump 1135 lpm (300 gpm). At only 160mm (6¼”) wide the SM21 can fit in small openings plus the cast iron impeller is within 19mm (¾”) of the base allowing it to remove more liquids than other pumps.

The SM21 also has a lifting eye, a 2.5″ discharge outlet and is fitted with hose whips plus flat face quick connect couplings. These features give the SM21 the ability to clear water from confined spaces or trenches plus a wide range of other applications where you need to move large volumes of water quickly and reliably.
