Overview

Type D pumps are used to transport clear water or liquids with physical and chemical properties similar to clear water, without solid particles, and at temperatures below 80℃. Suitable for mines, factories, and urban water supply and drainage.

Type DG pumps are multi-stage, segmented boiler feed pumps. They are used to transport clear water or other liquids with physical and chemical properties similar to clear water, without solid particles (abrasives). Suitable for medium and low-pressure boiler feed water, and can also be used as general multi-stage centrifugal clear water pumps. The temperature of the liquid being transported is -20~15℃.
