Goulds 3196 STX Replacement Pumps & Parts
ACCA Pumps manufactures and supplies complete ANSI process pumps and replacement parts for supported Goulds 3196 STX configurations. The STX is the small-frame portion of the 3196 family and is commonly used where compact ANSI B73.1 process-pump dimensions are required.

3196 STX Pump Size Matrix
Use the pump size and nameplate information to begin identification. Published aftermarket ANSI references group the following hydraulic sizes in the small 3196-type frame. Final pump and component selection should be verified against the installed unit, materials and service conditions.
| Pump Size | Discharge | Suction | ANSI Designation | Frame |
|---|---|---|---|---|
| 1 × 1½-6 | 1 in | 1½ in | AA | STX / Small Frame |
| 1½ × 3-6 | 1½ in | 3 in | AB | STX / Small Frame |
| 2 × 3-6 | 2 in | 3 in | Verify by configuration | STX / Small Frame |
| 1 × 1½-8 | 1 in | 1½ in | AA | STX / Small Frame |
| 1 × 1½-8 LF | 1 in | 1½ in | Low-flow configuration | STX / Small Frame |
| 1½ × 3-8 | 1½ in | 3 in | AB | STX / Small Frame |
Complete 3196 STX Replacement Pumps
ACCA can supply complete private-label ANSI process pumps for supported 3196 STX applications as well as pump ends and individual replacement components. ANSI B73.1 dimensional conventions make replacement sourcing practical, but hydraulic performance, internal construction, metallurgy and component interchangeability still must be checked for the specific pump.
Complete Pump
Configured pump assemblies for supported STX services with materials and sealing arrangement selected for the application.
Pump End / Wet End
Process-end assemblies and replacement wet-end components for maintenance or equipment replacement projects.
Power End
Frame, shaft, bearings, bearing housing and associated rotating-equipment components for supported STX arrangements.
Individual Parts
Cross-referenced components can be quoted from pump identification, OEM reference number, dimensions or removed-part samples.
3196 STX Engineering Reference
For STX identification, the published ANSI reference groups AA around 1 × 1½-6 and 1 × 1½-8, and AB around 1½ × 3-6 and 1½ × 3-8. The STX family also includes 2 × 3-6 and low-flow variants that should be verified from the installed pump information. Published small-frame reference dimensions include a 0.875-inch shaft, 3/16 × 3/16 keyway and 4-inch centerline height.
ACCA’s existing 3196 parts database contains STX-size casing and impeller references for 1 × 1½-6, 1½ × 3-6, 2 × 3-6, 1 × 1½-8 and 1½ × 3-8, plus common 3196 shaft-sleeve, bearing and sealing components.
3196 STX Replacement Parts
Casings
Replacement casings for supported STX hydraulic sizes and materials.
Open Impellers
Replacement impellers selected by pump size, diameter, material and service.
Shafts & Shaft Sleeves
STX shafts and sleeve configurations for supported power ends.
Seal Chambers & Stuffing Boxes
Standard, large-bore and applicable sealing-chamber configurations where verified.
Frames & Bearing Housings
Power-end structural components for supported STX arrangements.
Bearings & Maintenance Components
Bearings, gaskets, O-rings and associated maintenance parts identified to the installed configuration.
STX Engineering Reference
Published ANSI replacement-pump data for the small frame uses a nominal 0.875-inch shaft and approximately 4-inch centerline height. Dimensional references vary by supplier and construction, so ACCA verifies the required dimensions before representing a pump or part as interchangeable with a specific installed unit.
The back-pull-out ANSI process-pump arrangement permits inspection or removal of the rotating element without disturbing connected process piping when the installation is designed accordingly. Open-impeller arrangements also permit external clearance adjustment on applicable configurations.
Materials & Process Service
Complete pumps and replacement parts can be evaluated in common process-pump metallurgies including carbon steel, 316 stainless steel, duplex/CD4-type materials and higher alloys when required. Material selection depends on fluid chemistry, temperature, solids, corrosion and the specific component.
Chemical Processing
ANSI process service for acids, caustics, solvents and other process liquids subject to material review.
Pulp & Paper
Process and utility duties where an ANSI end-suction configuration is appropriate.
Refining & Petrochemical
General process services where the selected ANSI pump construction meets the project requirements.
General Industrial
Transfer, circulation, wash, utility and process duties across industrial facilities.
How to Identify the Correct STX Pump or Part
Send the pump model, size, serial number, existing part number when available, material of construction, required quantity and clear photographs of the nameplate and component. For older or undocumented equipment, ACCA can also review dimensional information and removed components for reverse-engineering evaluation.
For part-number research, use the ACCA Goulds Pump Parts Cross Reference. The reference includes 3196-family entries for impellers, shafts, stuffing-box and seal-chamber components and other replacement parts.
