DL, DLR type vertical multistage centrifugal pump | Fire Pumps
Overview and Uses:
DL (DLR) vertical multistage centrifugal pump is the use of the national recommended hydraulic model of energy efficient products IS type pump for vertical multi-stage multi-segmental structure. Screw the water segment, the middle, the water segment clamped into one. Each level of a water pump impeller installed, a wicket. By hydraulic axial force balance method to solve the residual axial force by the ball bearings under the shaft with grease. Seal with soft packing or mechanical seal. DL, DLR series pumps are suitable for industrial and urban water supply and drainage, high-rise building pressurized water, fire booster, long-distance water, heating, bathroom, heating and boiler water circulation booster, air conditioning and refrigeration systems and equipment for bottled water and other occasions.
1, advanced hydraulic model: high efficiency, wide range of performance.
2, the new structure, reliable operation: the abolition of the balance drum, which uses hydraulic axial force balance, balance drum completely solved easily corroded, easy bite, easy to wear problem, to ensure reliable operation.
3, less operating and maintenance costs: high quality mechanical seals, wear-resistant, leak-free, long life, low failure rate, with less operational maintenance costs.
4, smooth running, low noise: the use of low-speed motor, the pump is running smooth, low noise.
5, the vertical structure, small footprint.
