LG, DL type vertical multistage pump
DL type vertical multistage centrifugal pump is optimized and manufactured on the basis of horizontal multistage centrifugal pump, and its performance meets the requirements of the new national standard JB/T 2727-93. The inlet and outlet of the pump are divided into upper and lower structure, and the user can rotate the inlet and outlet direction from the vertical point of 90 degrees, 180 degrees and 270 degrees according to the actual situation during installation. The pump shaft and the motor shaft are on the same level, the seal is made of mechanical sealing device, and the bearing is made of low noise bearings, so the noise of the whole machine is very low and the vibration is very small, which greatly improves the use environment and improves the service life. It is characterized by small footprint, high lift, convenient installation and maintenance. It is suitable for water supply and drainage of high-rise buildings, fire pumps, factories, mines, oil fields and other units to transport water with a temperature below 90℃ or liquid with physical and chemical properties similar to water.
