DLDLR pumps fall into the category of vertical single-suction multi-stage segmental centrifugal pumps are used to transport the clear water containing no solid particles or other liquids with similar physical and chemical properties as clear water. It is mainly applicable for high-rise water supply and drainage in factories and mines.The flow range of the transported liquid is 4.9300m3/h, the lift head range 22239m, the related power range 1.5200kw, and the diameter range 40200mm.
DLDLR series pumps are applicable for industrial and urban water supply and drainage, pressurization and water supply for high-rise and fire control, long-distance water supply, pressurization of cold and hot water circulation for heating ,bathroom and boiler,water supply of air-conditioning refrigeration system, fitting for equipment and so on. The medium working temperature of DL type shall not exceed 80 while that of DLR shall not exceed 120.
