Tvilateral's centrifugal pumps Entrance of the type D and electrical units based on them are designed to pump water and other liquids that have similar properties with water in viscosity up to 36x10-6 m2/s (Z6SST) and chemical activity, temperature from 1 to 85 ° C, with The content of solid inclusions by mass is not more than 0.05%, not more than 0.2 mm and micro -hardness not more than 6.5 GPa (650 kgf/mm2).
type D pumps are made in climatic execution of UHL, T categories of placement 3.1, 2 according to GOST 15150-69.
Pumps D, 1D, 2D are used at the pumping stations of urban, industrial and rural water supply, in irrigation systems and in other industries.
Pumping D is not designed for operation In the explosion - and fire hazardous rooms.
D - a single-stage with a horizontal case of the case. The work wheel of the bilateral entrance. Rotor supports are rolling bearings. The input and pressure pipes are located in the lower part of the case, which allows disassembling the pump without dismantling the connecting sections of the pipeline.
