What These Part Examples Demonstrate


Complex Cast Geometry
Investment casting can form non-standard pump and valve geometries, curved profiles, connection structures and other features that would require extensive machining from solid material.
Internal Flow Passages
Valve bodies, pump housings, elbows and related parts may include internal flow-related structures that require suitable tooling and stable casting control.
Machined Sealing Faces
Sealing faces, flange surfaces, mounting faces and connection areas can be CNC machined according to drawing tolerances and surface requirements.
Precision Bores and Datum Features
Critical bores, positioning surfaces and assembly datums can be machined and inspected to support reliable fitting and installation.
Threads and Mounting Holes
Cast components can be supplied with drilled, tapped or machined holes, threads and mounting features according to the final assembly design.
Finished Component Delivery
Depending on project requirements, parts can be supplied with machining, heat treatment, polishing, passivation, coating, black oxide or other suitable finishing processes.

Materials Used for Pump & Valve Part Examples

Material selection depends on the working environment, corrosion exposure, mechanical load, machining requirements and applicable material standards.

Pump and valve components made from stainless carbon alloy duplex heat-resistant and wear-resistant steel
Stainless Steel
Used for corrosion-resistant pump and valve components requiring stable machining and clean surface quality.
Carbon Steel
A practical option for general fluid-handling and structural components where strength, machinability and cost efficiency are important.
Duplex Stainless Steel
Used for components exposed to more demanding corrosive, chloride-containing or marine-related environments.
Alloy Steel
Used for parts requiring improved strength, toughness, wear resistance or heat-treatment response.
Final material grades are confirmed according to customer drawings, service conditions, mechanical requirements and applicable standards.
