Type DMD Two-stage Pumps are engineered to produce as much head as two single-stage pumps in series, yet are much more compact in size. These rugged units are highly efficient and engineered to assure long and reliable service. Their single inlet construction permits a shorter span between bearings and half as many wearing rings to maintain. Packing boxes and bearing supports are integrally cast(except in the 10x10 DMD). An optional mechanical seal is available. Casing rings protect the casing from wear.

Sizes range from 2 in. to 10 in. discharge, with capacities to 3,500 gpm, and heads to 1,150 ft. Typical applications include water resources and industrial service such as high-head water works, hydraulic elevators, oil refineries, mining operations, chemical plants, and as boiler feed pumps.
