Replacement ANSI Pump Impellers for Goulds 3196 & Durco Mark III
Replacement impellers for verified Goulds 3196 and Durco Mark III configurations. Identify the installed pump family, size, frame or Group, OEM reference, material and impeller diameter/trim. Our engineering team reviews fit and material before quotation. Normal installation and clearance checks still apply.
Start with the installed pump platform
Open-impeller route. Verify frame, size, OEM reference, diameter and material.
POS 103 route for verified reverse-vane configurations. Verify Group, size, reference, trim and material.
Search the exact OEM number and review the matched replacement reference.
Identify the component position, then follow the supported impeller route where applicable.

Need help identifying the right impeller? Send your pump model, pump size, OEM part number, nameplate photo, or existing impeller details.
Don’t Know the Impeller Part Number?
A complete part number is not required to start. Send any available pump model/size, nameplate photo, old impeller photo or drawing, material, and current impeller diameter/trim.
What confirms a replacement?
- Installed pump family, frame or Group, and size
- OEM or controlled replacement reference when available
- Existing impeller diameter/trim and material
- Relevant mating configuration and normal installation checks
Identification routes by pump family
| Pump family | Typical identification route | Dedicated guide |
|---|---|---|
| Goulds 3196 | Frame + pump size + OEM reference + diameter/material | View 3196 Guide |
| Durco Mark III reverse-vane | Group + pump size + POS 103/OEM reference + trim/material | View Mark III Guide |
Fitment applies to a verified corresponding configuration. A pump family or POS code alone does not establish interchangeability.
Material selection follows the service conditions
Material is confirmed against fluid chemistry, concentration, temperature, solids and project specification. Commonly reviewed families include 316 stainless steel, CD4MCu, Alloy 20 and other verified alloys.
Manufacturing and dimensional inspection
Machining and dimensional inspection use the confirmed drawing, reference and mating interfaces. Dimensional records can support engineering release where applicable.
Dynamic balance and trim
Required diameter/trim, balance and configuration details are reviewed against the confirmed application and applicable pump documentation.
Reverse engineering and RFQ preparation
When an OEM reference is unavailable, a sample, drawing, nameplate and clear photographs can help establish which dimensions and interfaces need verification. Sample-based work remains subject to engineering review.
What to send
- Pump model, frame/Group and size
- Nameplate or sectional drawing
- OEM/replacement reference if known
- Current material and impeller diameter/trim
- Fluid, operating details and quantity
- Removed-impeller and mating-part photos, if available
Frequently Asked Questions
No. ASME describes B73.1 interchangeability in terms of pump mounting dimensions, suction and discharge nozzle locations, input shafts, baseplates and foundation bolt holes. A B73.1 designation alone does not identify the correct replacement impeller. Verify the pump family, size, frame or Group, OEM reference, trim and material. Read the ASME B73.1 scope.
Send the pump model and size, frame or Group, OEM part number if available, impeller diameter or trim, and material. A nameplate photo or drawing helps confirm the installed configuration.
Yes. Send a clear photo, drawing or sample details with the pump model and size. Engineering will review what can be verified before quotation.
The G196 / 3196 route covers open impellers identified by frame and size. The Mark III route covers reverse-vane impellers identified by Group and size. Use the matching guide to check the applicable reference and fitment details.
