Industry application

Pumps & Valves

Cast and machined flow components, pressure boundaries, impellers, housings and valve bodies.

Where our manufacturing route can fit

Pump and valve components often combine complex flow geometry with pressure boundaries, sealing interfaces and tightly controlled machined features. Investment casting can reduce machining on shaped bodies and impellers, while CNC machining establishes the bores, faces, threads, seat pockets and datum relationships that control assembly and leakage performance.

Typical component opportunities

  • pump and valve bodies, covers and bonnets
  • impellers, diffusers and other flow-path components
  • actuator, stem and mounting components
  • machined sealing, bearing and connection interfaces

Sourcing priorities

  • Pressure class, test pressure and acceptable leakage criterion
  • Media, temperature, corrosion and erosion exposure
  • Concentricity and datum control across seats, stems, bearings and flanges
  • Material verification, NDT and traceability for pressure-retaining parts

What to define in the RFQ

Operating pressure and temperature, process media, pressure-boundary requirements, sealing interfaces, material specification, NDT class and pressure/leak-test method.

Supply-chain objective

Keeping casting, machining and pressure verification under one coordinated route helps reduce datum handoffs and makes it easier to trace a finished pressure-containing component back through the manufacturing process.

Start with the drawing

Send the alloy, annual quantity and critical requirements.

Email is the fastest route for drawings and 3D files. The short form is available when email is inconvenient.

For the fastest drawing review, include:
  • 2D drawing / 3D file and revision
  • Material grade or service environment
  • Annual quantity or expected lot size
  • Critical tolerances, finish, inspection or pressure-test requirements

For drawings and 3D files, use direct email. info@chinaprecisionmetal.com.
