The 50ZJ-A33 High-chromium Alloy Impeller is the core flow component of the ZJ series horizontal single-stage single-suction centrifugal slurry pump. It is specially designed for transporting high-concentration and highly abrasive solid-liquid mixtures. The outlet diameter of this impeller is 50mm, and the impeller diameter is 33cm. It is cast using high-chromium alloy cast iron (such as CR26, CR27, etc.), and the impeller is connected to the pump shaft through a threaded joint. The blades are designed with 3 to 6 twisted blades, and there are 8 back blades distributed on the outer sides of the front and rear cover plates to balance the axial force and prevent impurities from entering the sealing area.

Products features

Outstanding wear and corrosion resistance: The 50ZJ-A33 High-chromium Alloy Impeller is made of high-chromium alloy material that undergoes special heat treatment. It has high Rockwell hardness and can effectively resist the erosion and wear caused by solid particles. At the same time, it has good corrosion resistance to alkaline slurries, significantly extending the service life.
Efficient and energy-saving design: Based on modern fluid mechanics theory, the hydraulic model of this impeller has been optimized. The impeller has high hydraulic efficiency and can reduce operating energy consumption.
Reliable and stable structure: The impeller is of a closed structure with high dynamic balance accuracy, ensuring smooth pump operation, low vibration, and low noise. Easy maintenance and replacement: As the core component of the dual-pump casing slurry pump, the 50ZJ-A33 High-chromium Alloy Impeller can be replaced separately after wear, without the need to replace the entire pump body. This results in low maintenance costs.
