The Honda WT40 Trash Pump moves the most water out of any Honda pump and can discharge 423 gallons a minute. The heavy-duty 4″ construction trash pump is powered by a Honda OHV GX390 389cc engine and designed for job sites and applications where high volume trash water capacity is needed. The large heavy-duty metal strainer allows up to 1 1/16 in. solids to pass through, as well as a large volume of water, helping to prevent clogging. It’s made of steel to withstand tough conditions.
