REPLACEMENT REFERENCE
Goulds 3196 Parts Material Matrix
A structured material-selection reference for 3196 casings, impellers, covers, shafts, sleeves, rings, and other wetted components.
Material Selection Requires the Full Service Envelope
Material names alone do not establish suitability. Final review should consider liquid composition, concentration, normal and upset temperature, solids, velocity, aeration, cleaning chemistry, contamination limits, and the observed failure mechanism of the existing component.
Common Material Families for 3196 Wet-End Parts
| Material family | Common cast designation | Typical components | Selection and documentation focus |
|---|---|---|---|
| 316 stainless steel | CF8M | Casing, impeller, cover | General corrosion review, casting specification, heat traceability |
| Alloy 20 | CN7M | Casing, impeller, cover, rings | Acid concentration and temperature review, PMI when specified |
| Hastelloy C-276 family | CW6M | Casing, impeller, cover | Severe corrosion review, casting quality, PMI and MTR requirements |
| Duplex stainless family | CD4MCuN / ASTM A890 Grade 1B | Casing, impeller, cover | Chloride, strength, casting heat treatment, PMI and ferrite control |
| Titanium Grade 2 family | C3 cast designation where applicable | Impeller, sleeve, rings, selected wet-end parts | Oxidizing service review, galling, mating materials, full traceability |
| Nickel-copper family | M35-1 / Monel family | Casing, impeller, cover | Reducing or marine service review, galvanic pairing, material verification |
Inputs for a Material Recommendation
- Liquid composition and concentration range
- Normal, startup, cleaning, and upset temperatures
- Solids, particle size, velocity, and erosion history
- Existing material and documented failure mode
- Component location and mating-material combination
- Required ASTM, EN, MTR, PMI, or customer specifications
