Wacker Neuson’s diaphragm pump line is designed to offer mud slurry pumping and seepage control. Engineered to be more rugged, these new pumps are designed to meet the demands of the jobsite and will handle solids up to 1.75 inches and up to 25-percent solids by volume. The PD pump series can pump virtually anything fluid enough to flow and can run dry for hours without damage. Five models are currently available in 2-inch and 3-inch suction/discharge diameters.
