Hengke supplies investment-cast pump impellers with drawing-based vane geometry, hubs and shaft connections. Casting and finish machining support fluid-handling components whose dimensions, material and inspection requirements are defined by the approved pump design.
Review vane passages, hub geometry, shaft fit and machining allowance against the pump drawing. Balance criteria, rotational speed and liquid conditions must be specified for the component; hydraulic performance belongs to the agreed complete-pump validation.
Available verification includes material documentation, dimensional reports and surface examination. Hardness checks, nondestructive testing or component-specific inspection can be agreed against the approved drawing and purchase specification.
