DL DLR SERIES VERTICAL MULTISTAGE CENTRIFUGAL PUMP

MODEL#150DL150-20X3 37KW Product introduction

DL and DLR series vertical multi-stage centrifugal pumps (low revolution speed n=1,450r/min) are new-type products developed by our company in accordance with the actual market demand for water supply to high-rise buildings and the standard of Fire Department of China: GB6245-1998 Performance Requirements and Test Methods for Fire Pumps. They are used to transport media which are free of hard grains and whose physical and chemical properties are similar as those of water. Its flow range is within 5~36m3/h, lift head range within 20~300m,related power range within 1.5~280kW and diameter range within DN40~DN200mm. One pump can be provided with 1 to 5 outlets.

Product features

This pump series adopts a high-efficiency and energy-saving hydraulic model which is excellent in China, thus being characterized by its high efficiency, smooth performance curve, wide operation range, conforming to relevant regulations of Fire Department and meeting needs of different users. Besides, it adopts a vertical, segmental structure, and has such advantages as stable running, low noise, a long service life, being space- effective and easy for installation and maintenance, etc.

Product use

Mainly applicable for domestic water supply to high-rise buildings, constant pressure water supply for fire control, automatic spraying water supply, automatic water curtain supply and so on, as well as for water supply and drainage for plants and mines, long- distance water supply, supportive use for different kinds of equipment, water use for various production processes, etc.

Working Conditions
