Boiler-grade Industrial Multi-stage Centrifugal Pump

CDJ booster multistage pump is a single suction multistage, segmented centrifugal pump, with a solid casing and impeller design,which can withstand the pressure of high-pressure pumping without deformation or breakage. It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, easy installation and maintenance. With large flow and high head, it can realize pressurized water or other liquids with physical and chemical properties similar to water. It can transport fluids over long distances and transport fluids through pipelines with minimal pressure loss, which is particularly important for industries that need to transport liquids over long distances.

1.High Pressure & High Efficiency
Stepwise pressure increase: Fluid passes through multiple impellers one after another, and the pressure accumulates step by step. It can easily achieve a high head of 46 meters to 500 meters or more.
Advanced hydraulic model: The impellers and flow channels are optimized through computational fluid dynamics (CFD) design. The efficiency is significantly improved, and some models can achieve an efficiency of over 92%.
Energy-saving operation: Compared to using multiple single-stage pumps in series, multi-stage pumps consume less energy and operate more economically under the same output.
2. Structural Design & Reliability
Compact design: Especially for vertical multi-stage pumps, a vertical structure with the motor placed on top is adopted, which occupies a small area and is particularly suitable for installation environments with limited space.
Balancing axial force: The use of hydraulic balancing method or balancing disc devices effectively solves the problem of traditional balancing drums being prone to rust and wear, ensuring smooth operation and extending service life. High-quality materials: The flow components can be made of stainless steel (such as 304, 316), cast iron, bronze, or even super duplex steel, etc., to withstand corrosive, abrasive or high-temperature media.
3.Sealing & Maintenance
Reliable shaft seal: Standardly equipped with soft packing seal or mechanical seal (made of hard alloy/fluororubber), ensuring no leakage during long-term operation. Some mechanical seal designs support quick replacement. Facilitated maintenance: The standardized interfaces and modular design make the inspection and replacement of key components easier, thereby reducing maintenance costs and time.

Municipal and Building Water Supply

Scene: Water supply systems for production lines, industrial cleaning systems for equipment and products, flushing systems requiring high-pressure water jets, and fire protection water supply systems for large industrial areas.
Advantages: Provide controllable and high-pressure water power for various industrial processes, meeting the needs of precise cleaning, process cooling, and safe fire protection.
Industrial Fluid Circulation & Transfer
Scene: Refrigerant water/cold water circulation in central air conditioning systems, water supply systems for boilers, steam condensate recovery, coolant supply for machine tools, and transportation of specific concentrations of acid and alkali liquids.
Advantages: Have good medium compatibility and operational reliability, suitable for the circulation and transfer of key liquids in HVAC, energy, and some chemical processes.
Water Treatment & Purification Processes
Scene: Water supply and backwashing of ultrafiltration systems, core high-pressure water supply for reverse osmosis systems, circulation of distillation devices, feed for separators, and water circulation filtration systems for large swimming pools.
Advantages: Provide stable high-pressure water sources for core water treatment processes, and are key equipment for efficient operation of systems such as reverse osmosis.
Modern Agricultural Irrigation
Scene: Irrigation systems for large areas of farmland, sprinkler and drip irrigation systems, long-distance, high-head water lifting and transportation from water sources (reservoirs, rivers, deep wells) to irrigation pipelines.
Advantages: Overcome terrain height differences and transmission resistance, achieve the working pressure required for water-saving irrigation systems, and ensure uniform and efficient irrigation for large areas of farmland.
