CDL Vertical Multistage Centrifugal Pump

Vertical multistage centrifugal pumps are an efficient and economical solution for “high head, low flow, and small space” applications. It mainly provide stable and 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.

Features

• 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.
• High efficiency and energy savings: The multi-stage centrifugal design achieves high energy conversion efficiency between stages, reducing operational energy consumption.
• 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.

Working Principle

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 stage of impellers and guide vanes 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.
