Liquid-cooling pump housing

Customer-defined FWS or CDU pump position; TCS use requires separate approval

A development assessment for a pressure-containing pump housing where the equipment owner explicitly accepts a copper-alloy route.

A low-lead alternative to consider where the customer approves the material and manufacturing route.

Development candidate only. Obtain written customer approval for the alloy and manufacturing route, then validate the actual coolant, complete wetted-material set, cleanliness and leakage requirements. This grade has no assumed approval for a technology cooling system.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.
