Product Overview
The Diesel Pump Housing and Diesel Pump Cover are important components of diesel fuel injection systems, designed to protect internal pump mechanisms and provide secure mounting interfaces for related parts. Their internal cavities, connection ports, sealing surfaces, and mounting features must correspond with the specific pump design to support accurate assembly and dependable operation. Sangroove (Jiangsu) Machinery Co., Ltd. manufactures diesel pump housings, covers, and related engine components for OEM applications across commercial vehicles, construction machinery, agricultural equipment, and industrial diesel engines.
Depending on the component design, production may involve resin sand casting, shell mold casting, or green sand casting, followed by machining of mounting holes, internal features, and sealing surfaces. Material options include HT250 and HT300 gray cast iron, with ductile iron and aluminum alloy available for evaluation according to project requirements. Surface protection and dimensional inspection can also be specified based on the intended application. Customers can provide 2D drawings or 3D CAD files to define dimensions, material grades, machining requirements, and inspection criteria for customized production.
Manufacturing Process
Tooling Preparation: Review component drawings, cavity geometry, wall sections, and machining allowances before developing the tooling.
Casting Production: Select a suitable process from resin sand, shell mold, green sand, or other confirmed casting methods according to the component design.
Material Control: Check chemical composition and material grade against the agreed technical requirements.
Machining Operations: Process specified mounting holes, internal features, connection points, and sealing surfaces.
Surface Protection: Apply the agreed anti-corrosion treatment, such as protective oil or painting, where required.
Quality Inspection: Verify critical dimensions and conduct additional checks, including air-tightness testing, where specified for the component.
Final Preparation: Complete the agreed inspection and prepare parts for delivery.
