FeatureSaltwater Corrosion Resistance,Pressure Tested
A marine centrifugal-pump impeller should be specified around the pump geometry and the medium it will encounter. This OEM/ODM service offers a custom impeller through precision lost-wax casting and CNC finishing. Bring the selected cast material and finished interfaces into the same enquiry so the manufacturing route addresses the intended pump component.
- A 316 stainless-steel impeller is available for the material enquiry.
- The principal route combines precision lost-wax casting with CNC finishing.
- Casting tolerance is CT6-7 per ISO 8062.
- Saltwater corrosion resistance is an impeller feature.
- Pressure testing is part of the stated impeller scope.
Describe the impeller within the pump assembly
The custom impeller drawing should identify its mating dimensions and the geometry required by the intended centrifugal pump. Include the operating medium and relevant service conditions so the component brief explains the duty behind the shape. A sand-casting enquiry can be evaluated as a separate route request for the selected part, with its own agreed manufacturing basis.
Choose the cast grade for the marine duty
Stainless steel, carbon steel, iron and corrosion-resistant steel are material enquiry options, and ASTM A351 provides a standard designation for discussion. Select the actual cast grade rather than treating all these choices as equivalent marine materials. The requested condition and finishing scope should follow that selection for the individual pump impeller.
Agree what pressure testing will demonstrate
Define the test pressure, method and acceptance conditions for the impeller order so the testing feature answers a specific project requirement. Polishing, heat treatment, blasting or a customer-required treatment can be included in the surface-processing discussion. For this marine pump component, the useful acceptance plan connects the chosen alloy, completed geometry and agreed test conditions instead of assuming a universal pressure rating.
