Product Details

DL vertical multistage centrifugal pump is used for conveying liquids with no hard particles and other similar liquids to water in physical and chemical properties .

DL type vertical multistage centrifugal pump adopts domestic excellent high efficiency and energy saving hydraulic model, with high efficiency, steady performance curve, wide operating range, in line with the relevant regulations of the fire department, to meet the needs of different users.

DL vertical multistage centrifugal pump adopts vertical segmental structure, which has the advantages of stable operation, low noise, long service life, small occupation area and convenient installation and maintenance.

DL type vertical multistage centrifugal pump main application

Dl-type vertical multi-stage centrifugal pump is mainly used for domestic water supply of high-rise buildings, constant pressure water supply of fire fighting, automatic spraying water, automatic water curtain water supply, etc. It can also be used for water supply and drainage of factories and mines, long-distance water delivery, various equipment and water for various production processes. The service temperature of DL type vertical multistage centrifugal pump medium shall not exceed 80 degree Celsius, and that of DLR type vertical multistage centrifugal pump shall not exceed 120 degree Celsius.
