DL vertical multistage centrifugal pump can be widely used in high-rise building fire, domestic water supply and air conditioning units circulating cooling water transport. Transmission medium, primarily for sucking diluted, clean, non-corrosive, water and physical and chemical properties similar to liquid water does not explode without solid particles or fibers. Performance range performance 1480r / min flow 9-504m3 / h Head 25-240m power 3-450kw working conditions Maximum operating temperature: 90 ℃ Maximum working pressure: 2.4MPa Pump DL pump things were from horizontal multistage centrifugal pump based on optimized design and manufacturing, its performance in line with the latest national standards and the requirements of JB / T2727-93 of. Screw the water segment, the middle, the water segment clamped together as one. Each level of a pump impeller installed, a wicket. Axial force using the water balance method to solve the residual axial force by a ball bearing with grease. Seal with soft packing or mechanical seal. Pump suction at the bottom, the outlet at the top. Users may need to adjust the water segment 90 °, the direction of 180 °, 270 ° of. This type of pump has high efficiency, wide range of performance, safe, stable, long life, small footprint, easy installation and maintenance features. Configuring the motor is equipped with Y-type vertical motor, motor power rating on the size and comply with IEC and DIN42637 standard, smooth motion, easy installation.
