CDL Single Pump Unit
Head Range: 15~350 m
Inlet/Outlet Range: DN25~DN200
Motor Power: 0.75~200 kW
Core Advantages
- High Efficiency and Energy Saving: using advanced hydraulic model and manufacturing process, the efficiency is more than 80%.
- Compact Structure: vertical design saves space, the water inlet and outlet are located at the same level of the pump seat, and can be directly connected to the pipeline system.
- Easy Maintenance: overall easy-to-disassemble seal design, mechanical seal is made of carbide and fluororubber, long life and easy to replace.
- Intelligent Protection: optional intelligent protector, real-time monitoring of abnormal conditions such as dry running, phase loss, overload, etc.
How Does a Centrifugal Pump Work
- Liquid Suction: The motor drives the impeller to rotate at high speed, and the liquid enters the center of the pump body through the inlet channel.
- Centrifugal Force Boosting: The liquid accelerates rotation driven by the impeller blades, generates centrifugal force, is thrown to the edge of the impeller and enters the guide shell.
- Multi-stage Series Boosting: The liquid passes through the multi-stage impeller and guide shell in turn, and each stage of the impeller boosts the liquid once, and finally outputs high-pressure water flow.
- Pressure Balance: The axial force is offset by the balance drum or balance hole design to reduce mechanical wear and ensure long-term stable operation of the pump.
