GGG50 SG-ductile-iron semi-open impeller and pump-part enquiries are offered using shell-mold casting with CNC finishing. The selected component can be defined through its blade geometry, mating interfaces and the condition required for the intended pump duty.
- Provide PDF, IGS or STP component information.
- Specify GGG50 with the complete governing material requirement.
- Mark blade, hub and shaft-interface geometry.
- Define cast and CNC-finished acceptance dimensions.
- State quantity, surface condition and inspection requirements.
Relate the semi-open geometry to the pump
Identify the blade arrangement and the relationship between the impeller and adjoining pump components. Include the operating medium and duty requirements relevant to the design. These details allow the casting and finishing enquiry to address the actual impeller rather than a general pump-part description.
Use the casting tolerance at the appropriate stage
CT7–CT10 is the stated casting-tolerance reference. Agree its controlled dimensions and inspection basis, and distinguish it from the acceptance needed on CNC-finished interfaces. The drawing should locate the surfaces and datums used for each requirement.
Specify the finish and approval records
Sandblasting, spray painting, powder coating and custom surface treatments are named options. Define their coverage and the finished condition required by the component. Professional inspection is stated; identify the records and checks needed for acceptance, and request applicable ISO9001:2015 supplier documentation. Keep the approved grade, geometry and finish with the order as the reference for the supplied shell-mold casting.
