DL (R) vertical multistage centrifugal pump

DL, DLR pump multi-stage segmented centrifugal pump is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, fire pressurization, long-distance water supply, heating, bathroom, boiler heating and cooling water cycle pressurization, air conditioning and refrigeration system water supply and equipment Matching and other occasions. The use temperature of DL type medium does not exceed 80℃, and the use temperature of DIR type medium does not exceed 120℃.

Structural features:

DL and DLR pumps are vertical single-suction multi-stage segmented centrifugal pumps, which are used to transport clear water without solid particles and liquids with physical and chemical properties similar to water. Mainly used for water supply in high-rise buildings, it can also be used in factories and mines for water supply and drainage and liquid transportation. The flow range is 4.9-200m3/h, the head range is 22-239m, the supporting power range is 1.5-160KW, and the caliber range is φ40-φ150mm. The DL and DLR series of multi-stage segmented centrifugal pumps produced by our factory are reliable in quality and stable in performance. All new and old customers are welcome to purchase.

The main purpose of DL type multistage centrifugal pump:
