ToleranceCustomer's Drawing Request
Custom gray-iron pump-casing sand castings include GJL20 and GJL25 references, with ductile iron available as a separate selection. Confirm the full material designation and governing specification for the chosen casing. OEM/ODM dimensions and tolerances follow the customer drawing for the actual industrial component.
Describe the casing around the pump duty
Show passage geometry, mounting points and the sealing or contacting areas relevant to the design. Identify the datum system and dimensions determining its fit with adjacent pump components. State the operating requirements and any service-specific acceptance needed for the selected casing.
Set drawing-based dimensional approval
Mark which surfaces are assessed in the supplied cast state and identify any additional work requested. Define acceptance limits and the measurement stage at functional interfaces. A reference casing should be tied to the controlled drawing, with wear or damage distinguished from the intended geometry.
- State quantity and the required revision.
- Identify the complete iron grade and condition.
- Mark functional and visible surfaces.
- Define material and dimensional approval records.
- State separately requested pump-duty checks.
Assign inspection and system documentation
The stated 100% inspection under an ISO9001-system reference should address the casing’s agreed characteristics, methods and acceptance limits. Include the records required for sample and production approval. Request applicable certificate scope alongside those requirements, keeping the selected material, drawing and supplied condition connected throughout the pump-casing order.
