ANSI Pump Shafts

Replacement ANSI B73.1 process-pump shafts, dimensioned to the OEM frame.

Pick a frame below to load it into the configurator. We cover the Goulds 3196 and its parts-interchangeable clones (Summit 2196, Griswold 811, PumpWorks PWA), plus the Durco Mark 3. The bearing journals, seal/sleeve seat, and coupling diameters are pre-dimensioned from the OEM manuals, with the journals set to the bearing-seat fit. You stay in control of material (4140 alloy default, 316 stainless for corrosive service), surface finish, tolerance class, and any added features. The drawing's title block stamps the source frame so any deviation from the standard is visible on the print. We confirm full machining geometry against your existing shaft or print before cutting.

Pump frames by OEM

Replacement ANSI process-pump shafts dimensioned to the OEM frame: Goulds 3196 (ST through X17), the Goulds 3796 self-primer and 3996 vertical in-line (same power end), the Goulds clone cluster (Summit 2196, Griswold 811, PumpWorks PWA), and Durco Mark 3 (Group 1 through 3). Real bearing journals set to the k5 bearing-seat fit, with seal/sleeve and coupling diameters, overhang, and bearing span from the OEM manuals. Click a frame to load a configurable starting point into the configurator.

Frequently Asked Questions

By the pump model and frame (Goulds 3196 ST through X17, Durco Mark 3 Group 1 through 3, or a clone such as Summit 2196 MTO), which fixes the bearing journals, seal/sleeve seat, and coupling diameters. Pick the card that matches your pump and load a shaft dimensioned to that frame. Every dimension stays editable in the configurator, and the drawing title block stamps the source frame so any deviation is visible on the print.
Each frame uses a deep-groove radial bearing inboard and an angular-contact thrust bearing (or duplex/double-row pair) outboard. For example, a Goulds 3196 MT runs 6309/7309 (45 mm) and a Durco Mark 3 Group 2 runs 6310/5310 (50 mm). The shaft loads with the journals already set to the k5 bearing-seat fit, a light interference for the rotating inner ring exactly as the OEM manuals specify, with the bearing-seat finish called out. You can adjust any fit in the configurator.
It depends. The Goulds 3196 shares its shaft geometry with a wide family: Goulds' own 3796 self-primer and 3996 vertical in-line mount the same power end, and the parts-clone cluster (Summit 2196, Griswold 811, PumpWorks PWA) copies it, all interchangeable. The Durco Mark 3 is a different geometry: ANSI/ASME B73.1 standardizes the pump envelope, not the shaft. We model each from its own OEM manual. Match the card to your actual pump model, not just the bore.
The cards default to 4140 alloy steel (annealed), the OEM material for sleeved general-duty shafts. For corrosive or solid-shaft service, switch to 316 stainless in the configurator. Material certs (MTRs) are available on request.
The bearing-journal diameters and bearing fits come straight from the OEM installation manuals, with the seal/sleeve, coupling, overhang, and bearing-span dimensions from the OEM data. We confirm the full machining geometry against your existing shaft or drawing before we cut. Send us the old shaft or a print and we'll match it.
We start with the Goulds 3196 (ST through X17), its clone cluster (Summit 2196, Griswold 811, PumpWorks PWA), and the Durco Mark 3 (Group 1 through 3). For a Sulzer, Flowserve non-Durco, or another model, contact us. Those are separate shaft geometries we add as demand warrants.
