What are the differences between pump parts made by stamping and those made by casting？

The main differences between stamping pump parts and casting pump parts are reflected in three aspects: ‌ processing technology, structural characteristics and applicable scenarios ‌.

Differences in processing techniques

 stamping ‌ : By applying pressure to metal sheets through molds to form them, it features high production efficiency and a material utilization rate of up to 70%-80%, making it suitable for mass production of simple or moderately complex parts. ‌

 casting ‌ : Molten metal is poured into a mold and cooled to form. It is suitable for manufacturing complex-structured or large-sized parts, but the processing cycle is relatively long. ‌

Structural characteristic differences

 stamping parts ‌ : These parts are usually thinner and lighter, with a smoother appearance, and are suitable for high-flow, standardized production scenarios (such as ordinary water quality transportation). ‌

 castings ‌ : As the material is processed in a solid state, the parts are heavier and more durable, making them suitable for scenarios with high impurity content, large flow rates, or special structural requirements (such as submersible sewage pumps, end suction pumps). ‌

Differences in applicable scenarios

 stamping parts ‌ : Recommended for applications with good water quality, low flow rate, price sensitivity and rapid delivery requirements. ‌

 castings ‌ : suitable for scenarios with complex structures, large flow rates, and high wear resistance requirements, such as treating wastewater containing impurities or transporting large flow rates. ‌
