Choosing an ANSI end-suction centrifugal process pump for an industrial flow-control setup usually comes down to a trade-off: pay new-pump money for zero service history, or take a unit with a clear specification and a lower entry price. The Goulds 3196 STi 1x1.5-8 sits squarely in the second group. At USD 1,625.00, it offers a way into a specific process-pump platform without the cost of a fresh build.
Quick verdict
If your operation handles chemical, pulp and paper, or general industrial fluids, this used Goulds 3196 STi is a practical buy at USD 1,625.00. The 6.75-inch impeller and 3500 RPM rating give you a tangible performance baseline, and the ductile iron construction is a reasonable match for demanding industrial fluids.
Who it suits
This unit makes the most sense for a plant or shop that already has the piping and foundations laid out for an ANSI process pump. It is a replacement-style purchase rather than a from-scratch selection. It also suits buyers who want the 3196 STi platform's applicability across chemical, pulp and paper, and industrial fluid handling without spending new-equipment money.
What stands out
The nameplate data is the strongest part of this unit: 3500 RPM and a 250 PSI rating. With a 1½-inch inlet and a 1-inch outlet, the hydraulics are clearly defined, so you can compare the pump's intended operating range against your own piping and pressure needs before you buy.
Meaningful trade-offs
The first trade-off is condition: this unit carries prior service history rather than a factory-new pedigree. The second is fit: the 1x1.5-8 size means the inlet and outlet are intentionally specific, and your existing pipe sizes and ANSI layout have to line up with those openings. The prior-service status is part of the bargain here, and the condition risk has to be weighed against the cost.
Goulds 3196 STi 1x1.5-8 ANSI End-Suction Centrifugal Process Pump 6.750
This is the specific unit on the table. On the plus side, it gives you a Goulds 3196 STi ANSI process pump with a 6.75-inch impeller and a 250 PSI nameplate rating. On the minus side, it comes with the accumulated wear of its previous application. If that condition fits your risk tolerance, the 3196 STi design gives you a solid base for chemical, pulp and paper, and industrial fluid handling.
Bottom line
The Goulds 3196 STi 1x1.5-8 is a credible option when you need an ANSI end-suction process pump for chemical, pulp and paper, or general industrial fluid handling. The 1½-inch inlet and 1-inch outlet sizing is the reason it is not a universal drop-in. Match that sizing reality to your application and the trade-offs you have weighed, and it is a sensible purchase.
