Вертикальный многоступенчатый центробежный насос серии CDL
The CDL series is a vertical multistage centrifugal pump equipped with a standard motor. The motor shaft is directly connected to the pump shaft via a coupling at the pump head. The overall structure uses tie rod bolts to securely fasten the pressure-resistant cylinder and flow components between the pump head and the inlet/outlet sections. The inlet and outlet ports at the bottom of the pump body are aligned on the same straight line. This pump can also be optionally equipped with an intelligent protector to effectively prevent faults such as dry running, phase loss, and overload.

Принцип работы
The working principle of the vertical multistage centrifugal pump is as follows: the motor drives the shaft to rotate multiple series-connected impellers at high speed. The fluid passes through each impeller and guide vane stage in sequence. In each stage, the rotating impeller transfers centrifugal force to the fluid, causing its kinetic energy and pressure energy to increase progressively. Finally, after being pressurized through multiple stages, the fluid is discharged vertically under the collection and straightening of the final-stage guide vanes.
Технические характеристики
Vertical multistage centrifugal pumps are an efficient and economical solution for “high head, low flow, and small space” applications. It mainly provides stable, high-head power for fluids.
Through the series connection of multiple impellers, they can generate pressure far higher than that of single-stage centrifugal pumps even at relatively low flow rates, making them suitable for scenarios where liquids need to be transported to high elevations or where high system pressures need to be overcome. Furthermore, the output flow is smooth and continuous, with minimal pulsation..

Advantages of Vertical Multistage Centrifugal Pump
High media compatibility
Suitable for conveying thin, clean, non-flammable, non-explosive liquids that do not contain solid particles or fibers.
Wide temperature range
Depending on the model selected, the pump can handle a wide range of liquid temperatures. The standard model covers temperatures from -15°C to +70°C, while the hot water model can withstand media temperatures up to +120°C.
Stable operating environment
Designed for an ambient temperature of up to +40°C and an altitude not exceeding 1,000 meters.
Compact vertical design
Features a vertical structure, occupying minimal floor space and significantly saving installation space.
Corrosion resistance and long service life
Key flow components are made of high-quality materials such as stainless steel, offering excellent corrosion resistance and extending service life.
High and stable discharge pressure
Multiple impellers operate in series to achieve high discharge pressure, with uniform flow and minimal pulsation.
