Custom Pump Parts for Replacement and OEM Projects
ANSI pump replacement work often starts with an obsolete component, a worn casting or an urgent part requirement without a current drawing. The manufacturing route is reviewed around the pump configuration, critical interfaces, material and agreed project scope.
Available supply form is confirmed as raw casting, semi-finished component or finished machined part according to the project.
Parts can be reviewed for Goulds 3196, Durco Mark III and selected 3175, 3180 and 3171 applications.
Over 10 years of experience in pump technology design, manufacturing, sales and service supports the engineering review.
Finished replacement components
ANSI Pump Components We Manufacture
Part scope and final machining are confirmed against the drawing, component geometry, reference part and project requirements.

Volute Casings and Pump Housings
Replacement casings assessed around flange faces, registers, nozzle locations and connected components.
Open and Enclosed Impellers
Impeller casting and machining routes reviewed around fit, balance, hydraulic geometry and service conditions.
Covers, Seal Chambers and Stuffing Box Covers
Components reviewed around seal faces, chamber geometry, gaskets and adjoining pump interfaces.
Shafts, Shaft Sleeves and Wear Rings
Rotating and wear components defined by shaft bore, keyway, fit, material and agreed inspection scope.
Adapters, Frames and Bearing Housings
Selected power-end components can be reviewed from drawings, reference numbers or customer samples.
Model and replacement applications
ANSI Pump Models and Replacement Applications
Use the model, frame, pump size and OEM part number to define the correct review scope.

From Drawing or Worn Sample to Finished Pump Part
Available manufacturing route, machining scope and inspection documents are confirmed according to the drawing, material, component geometry and project requirements.
Review the Input
Check pump model, frame, OEM reference, drawing, CAD file, nameplate and worn-part information.
Confirm Interfaces
Review flange faces, register fits, seal chamber, shaft bore, bearing bore, keyways and threaded holes.
Select the Route
Confirm alloy, casting route, mold or tooling requirement, machining scope and inspection needs.
Cast and Machine
Machine sealing faces, bores, registers, flange faces or other project-defined features when required.
Approve and Deliver
Inspection records, material documentation and first-article approval are supplied as agreed.
Materials for chemical-process pump components
Material Options for Corrosion and Wear Service
Available materials listed in the Yingsiman brochure include WCB, CF8M / 316SS, CD4M / CD4MCu, CN7M / Alloy 20, Hastelloy B and C, nickel alloys, titanium and zirconium.

Engineering proof for replacement fit
A Pump Replacement Is More Than a Material Match
Fitment depends on geometry, interfaces, configuration and service requirements. A replacement review should confirm:
Compare pump model, frame, OEM reference and available drawing or sample.
Check registers, flange faces, seal chamber, shaft and bearing interfaces.
Confirm alloy, machining scope and agreed inspection or material documentation before production.

FAQ
Questions Before You Request a Custom Pump Part
Can you manufacture a replacement pump part from a worn sample?
A worn sample can be used as a starting point for engineering review. Usable geometry, missing dimensions, material and the final manufacturing route must be confirmed before production.
Can you supply finished machined pump parts instead of raw castings?
Finished machining can be included when required by the approved drawing, component design and project scope.
Can you review Goulds 3196 and Durco Mark III components?
Selected replacement components can be reviewed for Goulds 3196 and Durco Mark III applications. Final fitment is confirmed by pump size, configuration, drawing, part number or reference sample.
What materials are available?
Material options include WCB, CF8M / 316SS, CD4M / CD4MCuN, CN7M / Alloy 20, Hastelloy, nickel alloys, titanium and zirconium, subject to project review.
Can you support repeat orders with custom molds?
Custom mold requirements can be reviewed for repeat replacement projects. Tooling ownership, approval and reuse terms should be confirmed in the quotation.
What inspection or material documents can be supplied?
Available inspection and material documents are confirmed according to the component, drawing and agreed project requirements.
