Dimensioned to the PumpWorks PWA LTi power end: 55 mm/50 mm bearing journals (6311/7310), 6-7/8″ (6.875″) bearing span. A PumpWorks PWA ANSI B73.1 process-pump shaft, parts-interchangeable with the Goulds 3196 (same shaft geometry). Threaded impeller nose, seal/sleeve seat, inboard and outboard bearing journals (set to the bearing-seat fit), and a keyed coupling end. Load it as a configurable starting point. We confirm full geometry against your shaft or print before we cut.

Material, tolerances, and additional features (bearing-journal and seal-fit tolerances, coupling keyseat, retaining-ring grooves, set-screw flats) stay editable in the configurator. Confirm the full machining geometry against your existing shaft or print before ordering. The drawing's title block stamps the source frame so any deviation from the standard is visible to your buyer and to us.
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 a parts-clone cluster (Summit 2196, Griswold 811, PumpWorks PWA) that uses the same shaft geometry, so those are 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.
