YP40T Water Pump

The YP40T tops this lineup with a 4-inch discharge port and a 357cc OHV 4-stroke engine, reaching a rated 449 gallons per minute, or 26,940 gallons per hour, more flow than any of the smaller-port trash pumps here. Its impeller still handles debris as large as 1-1/16 inch, about 27 mm, without clogging.

Trading head for volume

This model's 89-foot total head sits a little below some of this lineup's smaller-port pumps, since more of the larger engine's power goes toward raw volume through the bigger opening rather than pushing water higher. A 26-foot suction rating carries through unchanged, covering how deep below the pump the water source can sit.

Durability where it counts

The impeller and volute case are cast iron rather than a lighter alloy, built to stand up to the sand, grit, and silt that come with debris-laden pumping, and the seal is a Japanese-made silicon carbide design rated more durable than an older carbon-ceramic seal. The 4-inch NPT fittings call for hose sized to match, rather than reusing a smaller-port hose.
