In fluid end and pump-component procurement, “quality documents required” is not a complete requirement. The necessary records vary by product, project and customer system. Defining the acceptance basis during quotation and technical clarification avoids late additions that can affect production and delivery.
1. Match document requirements to the product
Complete fluid ends, bodies, valves, seats, plungers, packing and repair kits have different manufacturing routes. The document list should identify the item number, drawing revision, quantity and batch rather than rely on a generic statement.
2. Raw material and batch information
Where material certification is required, define the document type, material grade and heat or batch relationship. Incoming identification should remain connected to production records and the finished product.
3. In-process inspection and special processes
Critical dimensions can be checked against the approved drawing during CNC machining. For heat treatment, surface enhancement or other special processes, state the required process, hardness or record. NDT methods, sampling ratio and acceptance criteria must be agreed before work is arranged.
4. Final inspection and testing
Final inspection can review dimensions, appearance, marking, assembly status and applicable performance items. Pressure testing, NDT or third-party witness requirements should identify the product, test conditions, acceptance criteria and report format.
5. Packing and delivery documents
Before release, check product identification, quantity, packing and the document list so that item and batch references match the physical goods. Overseas projects should also define language, electronic or paper format, shipping marks and document-submission timing.
Documents to confirm before the order
| Base documents | Approved drawing, BOM, item number and order-specific technical requirements. |
|---|---|
| Material documents | Agreed material certificates and batch information. |
| Process records | Critical dimensions, hardness and agreed special-process records. |
| Inspection reports | Final inspection and agreed NDT or pressure-test reports. |
| Delivery records | Product identification, packing list, inspection status and traceability. |
AOFIDE maintains certified quality, environmental and occupational health and safety management systems, together with a process covering incoming inspection, manufacturing, in-process inspection, manufacturing completion, final inspection and pre-shipment sampling. Management-system certification does not replace order-specific material, dimensional, test or acceptance documents.
