Pumpenherstellung
Vorteile
Pump products typically require high casting precision and material properties, and Leierwo’s expertise in pump casting is particularly prominent. The company’s extensive application in pump and valve accessories demonstrates its mastery of the casting process for key components such as pump bodies, impellers, and sleeves. Precision casting technology effectively controls the uniformity of casting wall thickness and internal cavity accuracy, reducing subsequent processing and improving overall efficiency. Furthermore, the company can recommend the most appropriate casting process based on component structure to further optimize the performance of pump products and meet the corrosion resistance, heat resistance, and fluid dynamics requirements of various industries.
Main Material Selection
Pump castings are exposed to liquid media for extended periods and often face challenges such as corrosion, wear, and cavitation. Therefore, materials must possess high corrosion and wear resistance, as well as excellent casting properties.
Common Materials:
Stainless Steel Series:
316/316L: Preferred for pump casings, impellers, and shafts, resistant to acids, alkalis, and chloride ion corrosion. 2205 Duplex Steel: High strength and high pitting resistance, suitable for seawater pumps and chemical pumps. 304/304L: General-purpose pump components, suitable for water treatment and the food industry. Carbon Steel Series:
1045: For pump shafts and casings in non-corrosive environments. 4130: For high-temperature, high-pressure pump structural components.
Special Alloy Series:
C95400 Bronze: Suitable for seawater pump sleeves and sliding components, offering excellent wear resistance and self-lubrication.
Cobalt Alloys (such as Co6): Used for sealing surfaces or impellers in high-wear, high-temperature pumps.

Key Casting Service Options
The fluid dynamics performance of pump components (such as impellers and pump bodies) depends on casting accuracy, and this type of service has a clear division of labor!
Investment casting: Dominates complex flow path parts. The impeller is the heart of the pump, and its blade curve (which must conform to the fluid dynamics design) has a complex shape. Dimensional deviations directly reduce pump efficiency. Investment casting can achieve blade profile accuracy of +0.1mm and a surface finish of Ra3.2um or less, reducing fluid resistance.
Sand casting: Used for fundamental components such as the pump body. The pump body, as the outer shell, has a relatively regular shape (mostly cylindrical or square). In mass production, sand casting offers low cost and short cycle times, meeting the basic requirements of “structural support + fluid flow passage.”
CNC machining: Ensures transmission and sealing accuracy. The connection between the pump shaft and impeller, as well as the sealing surface between the pump body and the end cover, require CNC machining to ensure concentricity (≤0.01mm) and flatness to prevent vibration or leakage caused by eccentricity during operation.
