Electric centrifugal pump unit type "D"

The electric pump units of "D" type are designed for pumping water and liquids similar to water in viscosity and chemical activity, temperature up to 358K (850C) with the content of solid inclusions not exceeding 0,05% by mass and size not exceeding 0,2mm, microhardness not exceeding 6,5 GPa (650kgf/mm2). The units have a pump casing with axial horizontal split and semispiral liquid supply to the double-sided impeller. The pumps have the possibility of replacing internal parts of the flowing part without disconnecting the connections from the pipework.
