Replacement configurations for existing Goulds 3196-family and Durco Mark III-family ANSI process pumps where stainless steel is not enough. Select the installed pump platform first, then confirm the required wet-end material, size and replacement scope.
Use the G196 platform when the installed pump is based on the Goulds 3196 family. Match the pump size, frame, duty, sealing arrangement and required alloy before quotation.
G196 series reference: up to 7,000 GPM / 730 ft / 375 PSIG / 700°F.
Use the D Mark III platform when the installed pump is based on the Durco Mark III family. Match the group, pump size, duty, sealing arrangement and required alloy before quotation.
D Mark III series reference: up to 7,500 GPM / 990 ft / 400 psi / -100°F to 700°F.
G196 and D Mark III are separate replacement platforms. Do not assume one wet end or part is interchangeable with both.
The exact replacement scope is matched to the installed platform, size/group, OEM reference and required material.
| Material family | Typical quote scope | Verification required |
|---|---|---|
| CD4M / CD4MCu | Selected wet-end parts / pump configurations | Size, component, fluid, temperature |
| CN7M / Alloy 20 family | Selected wet-end parts / pump configurations | Size, chemistry, concentration, temperature |
| Hastelloy B / C | Selected high-alloy wetted components | Exact grade, size, process chemistry |
| Nickel | Selected wetted components | Exact grade, size, process chemistry |
| Titanium | Selected wetted components / configurations | Grade, component, fluid, temperature |
| Zirconium Alloy | Selected severe-corrosion components | Exact grade, component and service review |
CF8M / 316SS and other standard construction materials remain available where the replacement specification requires them.
Casting and machining managed for replacement pump components.
Dynamic balancing for impellers.
Pressure testing for casings.
Fitment checks for replacement parts.
Inspection records for traceability.
Reverse engineering from customer drawings or samples when required.
The replacement platform and material are confirmed together; material alone does not define the correct pump configuration.
Start with the operating data you have. Send installed platform, group/frame, process fluid, temperature, required alloy, seal arrangement and any OEM part number.
