Semi-open impellers for nuclear equipment pumps

Name：Semi-open impellers for nuclear equipment pumps

Material: Stainless steel (Duplex SS), Alloy Steel

Unit Weight: 0.5-130kg

Manufacturing process: Investment casting, silica sol technique.

This casting part is the impeller, used for different types of centrifugal pumps. It is made of various materials such as nuclear-grade alloys (e.g., stainless steel 316L, Inconel) and has good corrosion resistance. It is designed to withstand the extreme conditions: high temperatures (300℃+), radiation exposure, and pressure surges without failure..

Impellers are statically or dynamically balanced before shipment. The multi-blades with good formation ensure the high performance of the complete pump system.

The impeller is essential for maintaining optimal performance for whole pump. It is a rotor used to increase the kinetic energy of the flow. It can drive the flow of primary/secondary coolant (e.g., pressurized water, liquid sodium) to transfer heat from the reactor core to steam generators or heat exchangers and ensure stable thermal regulation to prevent overheating. The diameter of the impeller can be adjusted according to different function requirements.

The impeller plays an indispensable role in the pump system. It is renowned for its excellent corrosion resistance, high strength, and long lifespan, are widely utilized across a diverse range of industries such as nuclear power plant, paper and pulp equipment, food&beverage, water treatment, chemical and oil&gas...
