CNP Vertical Multistage Pump

CNP Vertical multistage pump is a type of centrifugal pump manufactured by CNP (Nanfang Pump Industry Co., Ltd) designed to deliver high pressure at relatively low to medium flow rates. It is called “multistage” because it contains multiple impellers (stages) stacked vertically on a common shaft. Each stage increases the pressure of the fluid, making it suitable for applications requiring high heads (pressure).

Performance Range

• Flow rate: Typically from 1 to 240 m³/hr
• Head (pressure): Up to 305 meters or more
• Liquid temp range: –15°C to +120°C (standard to hot water types)
• Operating pressure: Up to 30 bar (or higher depending on model)

Advantages

• High pressure output with minimal floor space
• Energy efficient and suitable for continuous duty
• Corrosion-resistant materials (for stainless steel models)
• Modular design allows easy maintenance and parts replacement
• Quiet operation with minimal vibration

Applications

• Water supply & pressure boosting (residential, commercial, high-rise buildings)
• Boiler feed water
• Reverse osmosis (RO) and water treatment systems
• Cooling and HVAC systems
• Fire-fighting systems
• Industrial process water handling
