When you're choosing industrial pumps for flow control, the decision is a balancing act: capacity needs to match your line size, head requirements, and the metallurgy of the fluid you're moving, all without blowing the capital budget. These four ANSI end-suction process pumps range in price from $1,625 to $6,500, so the decision is just as much about duty cycle as it is about upfront cost. Here's how to choose.
Quick Take
- PumpWorks 101-00145-0000 / PWA 2x3x8 - The only new unit in the group, built to ANSI/ASME B73.1 with a carbon steel (WCB) casing, 316SS shaft, and oil-bath lubrication with ISOMAG magnetic bearing isolators.
- Goulds 3196 STi 1x1.5-8 - Used US-built ductile iron pump with a 6.750" impeller and a 3500 RPM rating.
- Goulds 3196 i-Frame 1x1.5-8 316SS - Used 316SS pump with an 8" impeller, sold as pump only.
- Goulds 3196 XLT-X 8x10-15G 316SS - Used large-frame 316SS pump rated for 2940 GPM at 144 ft head.
Price Comparison
| Pump | Price | Bar |
|---|---|---|
| Goulds 3196 STi 1x1.5-8 | $1,625.00 | |
| Goulds 3196 i-Frame 1x1.5-8 | $2,200.00 | |
| PumpWorks PWA 2x3x8 | $3,324.45 | |
| Goulds 3196 XLT-X 8x10-15G | $6,500.00 |
Decision Matrix
| Pump | Best For | Watch Out For |
|---|---|---|
| PumpWorks 2x3x8 | New ANSI B73.1 installation | Smaller line size (3x2) and higher price than the two used Goulds |
| Goulds 3196 STi | Tight budget, lower-flow duty | Ductile iron, not 316SS; used unit |
| Goulds 3196 i-Frame | 316SS wetted parts at a moderate price | Pump only; no motor or baseplate included |
| Goulds 3196 XLT-X | High-flow process line near 2940 GPM | Highest price and pump casing/end only |
PumpWorks 101-00145-0000 PWA 2x3x8 ANSI B73.1 Centrifugal Process Pump
The PumpWorks stands out because it is the only new listing in this group. It's built to ANSI/ASME B73.1 with a carbon steel (WCB) casing, a 316 stainless steel shaft, and oil-bath lubrication with ISOMAG magnetic bearing isolators on both bearing positions. The 2x3x8 configuration gives you a 3-inch suction and a 2-inch discharge, with 150# flat-face flanged connections. If you need a new pump and don't want to evaluate used equipment, this is the straightforward pick. At $3,324.45, it's more expensive than the two smaller Goulds units, and the 3x2 line size limits flow compared to the 8x10-15G XLT-X.
Goulds 3196 STi 1x1.5-8 ANSI End-Suction Centrifugal Process Pump 6.750
The Goulds 3196 STi is the budget entry at $1,625.00. This used, US-built pump uses a ductile iron construction and carries a 6.750-inch impeller, 3500 RPM rating, and 250 PSI nameplate data. Its 1x1.5-8 size means a 1.5-inch inlet and 1-inch outlet, so it's aimed at lower-flow transfer services rather than large process lines. The STi designation points to the straight centrifugal pump family, and the 1x1.5-8 size keeps it in the smaller end of the 3196 range. If your flow requirement is modest and ductile iron suits the fluid, this unit keeps the initial capital outlay down. Just remember you're buying used equipment with a smaller nozzle size, so verify your piping and duty before committing.
Goulds 3196 i-Frame Centrifugal Process Pump 1x1.5-8 316SS
Priced at $2,200.00, the Goulds 3196 i-Frame is a used 316SS process pump with an 8-inch impeller. The all-stainless construction is the main reason to consider it over the ductile iron STi: when the fluid requires better corrosion resistance, the 316SS wetted path matters more than the $575 difference. This unit comes from Canada and is listed as pump only, meaning no motor, baseplate, or coupling is included. That's not a dealbreaker if you already have a motor and mounting arrangement, but it adds to the total cost. With a 1x1.5-8 size, you still get the smaller 1.5-inch inlet / 1-inch outlet envelope, so treat it as a moderate-flow stainless option.
Goulds 3196 XLT-X Centrifugal Process Pump 8x10-15G 316SS
At $6,500.00, the Goulds 3196 XLT-X is the high-capacity option here. It's a used 316SS unit with an 8x10-15G size, nameplate data showing 2940 GPM capacity, 1800 RPM, and 144 feet of head. That flow rating puts it in a different class from the 1x1.5-8 pumps, so it's the one to pick when the process line needs serious volume. The trade-off is the price: it carries the highest price in the group. The unit is sold as pump casing/end only, so plan on sourcing the rest of the pump assembly. If your flow-control requirement is in the thousands of gallons per minute range, this is the only option in the group that reaches it.
Final Recommendation
Choose the PumpWorks 2x3x8 when you want a new ANSI B73.1 pump with a carbon steel casing and 316SS shaft, and your flow needs fit a 3x2 nozzle. Choose the Goulds 3196 STi for the lowest entry cost and a smaller duty. Choose the Goulds 3196 i-Frame 316SS when you need stainless metallurgy without the XLT-X price tag. Choose the Goulds 3196 XLT-X when the application demands around 2940 GPM and a 144-foot head.
