CDL series vertical centrifugal pumps have proven their reliability in industrial high-pressure washing, high-rise water supply, agricultural sprinkler irrigation, reverse osmosis pressure boosting, and boiler feed water applications. With its reasonable structure, durable materials, high efficiency and energy savings, simple maintenance, and user-friendly operation, this equipment has become the preferred choice for pressure boosting and circulation in industrial, municipal, and agricultural settings.
This machine features a three-stage layout with vertical orientation, multiple stages, and in-line inlet/outlet alignment. Its horizontal, co-directional inlet and outlet allow direct insertion into pipelines without requiring bases or vibration-damping platforms, resulting in an exceptionally compact footprint. Compared to traditional horizontal multistage pumps, its footprint is reduced by approximately 60%. This design significantly saves construction costs and shortens production preparation time for applications in high-rise buildings and underground pump rooms.
To enhance pumping efficiency, CDL multistage centrifugal pump features a stainless steel impeller and volute manufactured through single-piece stamping and laser welding. Its flow channel roughness is only one-fifth that of cast components, thereby reducing flow resistance and ensuring smoother operation. Meanwhile, the multi-stage series configuration delivers a flat efficiency curve, maintaining high energy efficiency under variable loads. This pump saves approximately 10% more electricity compared to traditional cast iron multistage pumps. The motor of this machine is directly coupled to the pump head via a coupling. Its mechanical seal features a quick-release chuck design, enabling on-site seal replacement without disassembling pipelines or hoisting the motor. This not only reduces downtime by 90% compared to traditional split-case multistage pumps but also significantly lowers maintenance costs and enhances economic efficiency.
This pump's head incorporates a three-in-one protector against dry running, phase loss, and overload, enabling native compatibility with variable frequency motors. When equipped with a control panel, it delivers constant pressure water supply within ±0.1 MPa. The system cost is approximately 15% lower than traditional centrifugal pumps, while commissioning time is reduced from two days to just two hours. This makes it highly suitable for unmanned applications in buildings, agriculture, and small industrial stations. CDL series centrifugal pumps combine space-saving design, smoother flow delivery, and reduced maintenance downtime, making them an all-around solution for industrial, municipal, agricultural, firefighting, boiler, and water treatment applications.
