The Competitive Price Casting Parts Sealing Casing from Hongtuo Mechanical Casting Co., Ltd is manufactured in gray iron or ductile iron, designed for use in water pump systems where structural integrity and sealing performance are critical. The casing features precision-machined sealing surfaces with dimensional tolerances typically held to ±0.3 mm, ensuring compatibility with standard pump flanges and gasket interfaces. This component is engineered for continuous operation under pressures up to 16 bar, with wall thicknesses ranging from 8 mm to 15 mm depending on pump size and application.
Gray iron is selected for its vibration damping and machinability, while ductile iron is used where higher tensile strength or impact resistance is required. Both materials conform to ASTM A48 Class 30 for gray iron and ASTM A536 Grade 65-45-12 for ductile iron. Surface finish on sealing faces is typically ground to 3.2 µm Ra, and internal passages are cleaned to remove sand and core residue. No coatings or platings are applied unless specified by the buyer, as the base material provides sufficient corrosion resistance in water-based environments.
This sealing casing is purchased by manufacturers of industrial, agricultural, and municipal water pumps, particularly in regions with high demand for reliable fluid handling systems. Buyers typically order in volumes of 500 to 5,000 units per shipment, with packaging in wooden crates or palletized cartons. Trade terms are commonly FOB Guangzhou or CIF destination port. OEM customization is available for bore diameters, mounting holes, and flange profiles upon request.

Before placing an order, verify the material grade (gray or ductile iron), dimensional drawings, and surface finish requirements with the supplier. Request a sample casting with a material test report to confirm mechanical properties and chemical composition. Confirm that the casting is free of sand inclusions and that machining tolerances match your pump assembly specifications.
Lead time is typically 30 to 45 days after drawing approval. Incoterms are commonly FOB Guangzhou, but CIF or CFR can be negotiated. Payment terms are usually 30% advance, 70% against copy of bill of lading. Packaging is in wooden crates with moisture barriers; confirm crate dimensions for container loading efficiency. Ensure the supplier provides export documentation including commercial invoice, packing list, and certificate of origin.
Perform a pre-shipment inspection for dimensional accuracy, surface finish, and internal cleanliness. Use calipers and surface roughness gauges to validate critical dimensions. Check for cracks or porosity under magnification. Request a batch test report for tensile strength and hardness. Retain samples for quality reference. Ensure the supplier provides a signed declaration of conformity for the material grade used.
