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.
