Product namePump Body Casting
OEM pump-body precision investment casting is offered in CF8, CF8M, CF3 and CF3M stainless steel, with custom sizing and surface treatment. Machining and heat treatment are part of the processing scope. The DN300 reference gives the inquiry a nominal-size direction, while the actual body design remains defined by the pump drawing.
DN300 at the pump-body interface
Connect the DN300 inquiry to the actual connection dimensions and mating geometry required by the pump. The nominal reference should be accompanied by the body drawing so the casting can be discussed as a particular component. Identify the interfaces that determine assembly fit and keep their acceptance requirements connected to the same drawing revision.
Selecting CF8, CF8M, CF3 or CF3M
The four stainless designations are material alternatives for the body. Select the required grade against the intended fluid and working conditions, then carry that selection into the material and inspection requirements. This gives the casting inquiry a specific alloy basis while leaving project-dependent operating suitability to be confirmed for the chosen pump design.
Machining, heat treatment and the finished surface
Machining and heat treatment should be agreed around the selected material and body geometry. Mark the areas requiring dimensional work and describe the requested surface treatment, since the finish is customizable. Considering these stages together helps define the condition of the body being requested without assuming a machining tolerance or heat-treatment schedule.
- Identify the DN300 pump-body drawing and mating interfaces.
- Select the stainless grade and requested finish.
- Agree the machined dimensions and inspection acceptance for the body.
The inquiry concerns the body casting within a pump design. Linking the interfaces, material and processing requirements gives the OEM discussion practical detail without treating the casting as a complete pump or assigning an unstated hydraulic duty.
