Import Casting Iron Pump Housing Parts — Buy in Bulk from Supplier in China

Botou City Yihai Machine & Equipment Co., Ltd. produces pump housing parts from casting iron using investment casting and precision casting methods. These components are designed for centrifugal and positive displacement pumps used in water treatment, chemical processing, and industrial fluid systems. The material is typically gray cast iron with controlled carbon and silicon levels to ensure castability and mechanical stability under pressure.

Gray cast iron grades used in pump housings commonly contain 2.8% to 3.5% carbon and 1.8% to 2.7% silicon. Wall thickness ranges from 8mm to 25mm depending on pump size and pressure rating. Internal passages are machined to tight tolerances after casting. Surface finish is as-cast unless specified, with no internal coatings. The supplier performs machining, heat treatment, sandblasting, and electroplating as post-processing steps, but these are optional and must be requested.

These parts are sourced by pump manufacturers in Europe, Southeast Asia, and North America for OEM and replacement applications. Buyers typically require dimensional compliance to ISO 5199 or ANSI B73.1 standards. Minimum order quantity is not stated but batch production is standard. Lead time and incoterms must be confirmed.
