# Pump and Valve Housing Casting China

Pump and valve housings are not simple aluminum shapes. The buyer is sourcing a pressure-related component where casting route, porosity control, machining datums, sealing faces, leak testing, and inspection records all affect quote quality.

RFQ data buyers should prepare

Send:

  • 2D drawing and STEP model
  • sealed cavity or pressure-path notes
  • working pressure and leak-test requirement
  • alloy, heat treatment, and mechanical requirements
  • machining scope for ports, threads, bores, and sealing lands
  • CMM datum expectations
  • material certificate, NDT, PPAP, or FAI needs
  • annual volume, sample quantity, and delivery destination

Supplier questions to ask

A useful supplier response should explain process route, tooling path, machining assumptions, high-risk porosity zones, leak-test stage, and the records included with samples or production shipments.

If the supplier only quotes casting weight, the comparison is incomplete.

Bohua RFQ path

Bohua can review pump and valve housing RFQs for leak-test planning, machining scope, CMM datums, and supplier evidence. Start from the pump housing page, valve body page, leak-tight casting hub, or send drawings through the formal RFQ form.
