Goulds 3196 Impeller Replacement: Item 101 Fitment Guide
Review the installed configuration before ordering a Goulds 3196 replacement impeller. Item 101 identifies the impeller position; fitment still depends on pump size and frame, exact reference, material, impeller diameter and mating interfaces. Confirm the applicable installation and cold-clearance procedure before release.

The same family includes multiple sizes and configurations. Use the information available to reduce the risk of ordering the wrong impeller.
Goulds 3196 Cold Impeller Clearance Reference
Clearance is not a single value for the entire family. It changes with the drive unit and service temperature.

| Drive unit | ≤93°C / 200°F | 121°C / 250°F | 149°C / 300°F | 177°C / 350°F | 204°C / 400°F |

Inspect the Impeller Before Replacement
Main vanes
Check for deep grooves and uneven wear against the applicable IOM criteria.
Pump-out vanes
Check the rear vanes for wear or deformation.
Edges and surfaces
Check for erosion, corrosion, cavitation damage, vane-edge loss, rubbing marks, cracks, and evidence that the installed clearance has changed.
Material Selection for Replacement Impellers
Material family alone does not replace a review of chemistry, concentration, temperature, solids, and project specification. Final material selection depends on the actual fluid, concentration, temperature, solids, and project requirements.
| Family | Designation to verify | What to confirm |
|---|---|---|
| CF8M / 316SS | ASTM grade applicable to the part | Concentration, chlorides, temperature, and solids. |
| CD4MCuN | Duplex grade per documentation | Chlorides, erosion, and project requirements. |
| CN7M / Alloy 20 | Exact grade | Acid, concentration, and temperature. |
| Hastelloy / Titanium | Exact required grade | Complete chemistry and oxidizing/reducing conditions. |
What to Send for an Impeller RFQ
Send the frame, size, OEM reference, current diameter, material, and photographs. If information is missing, the nameplate and removed part can help start the review.

| What you have | What to send | What remains to be confirmed |
|---|---|---|
| An OEM impeller part number | Exact number and suffix, pump nameplate, size/frame and any controlled drawing or BOM. | Current trim, material, model generation and retained mating interfaces. |
| A nameplate but no part number | Clear nameplate and whole-pump photos, size/frame and current impeller information if available. | Correct Item 101 reference and the applicable impeller configuration. |
| A removed impeller or worn component | Photos of both sides, markings and damage; available dimensional records and original pump identity. | Identity, material, usable dimensions and whether a sample/drawing review is required. |
Keep Item 101 separate from the unique OEM part number. A family name or visual similarity is not a fitment approval. Use the clearance table above only within its stated model, drive-unit and temperature scope; CV, LF and other variants require their own applicable instructions.
Review the Goulds 3196 replacement-parts category for the broader supply route, or the replacement compatibility checklist when retained parts or installation interfaces need assessment.

Impeller Replacement Questions
Do all Goulds 3196 frames use the same clearance?
No. The value changes with the drive unit and service temperature; confirm the applicable IOM.
What does Item 101 mean?
It is the position reference used to identify the impeller in the applicable documentation.
Can I request a quote using only “Goulds 3196”?
It is better to include size, frame, OEM reference, material, diameter, or photographs to confirm the configuration.
