NPTF discharge and is furnished with hose whips and flush face quick disconnect couplers.

The Stanley SM21 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.

Submersed into the water and with its easy hookup to a power unit, the SM21 is instantly pumping.
