The Multiquip MQD2HA is a professional-grade 2-inch diaphragm pump engineered to move the most challenging fluids, including thick sludge, mud, and water with high solid content. Powered by a reliable 3.5 HP Honda GX120 engine, this positive-displacement pump is the industry standard for seepage control and dewatering excavations where centrifugal pumps might clog or fail.
