For industrial pumps flow control, the Goulds 3196 process pump is a common building block, but the right version depends on the liquid, the flow, and how much you can put into the pump itself. These four options span $1,625 to $6,500, so the first move is to sort out flow class and material. The useful payoff is simple: match the pump's material and size to the liquid, and keep the included components in mind before you budget.
Quick take
If you're moving low volumes of corrosive or high-purity fluid, the Goulds 3196LF is the one built for it. If you want the smallest cash outlay in this group, the Goulds 3196 STi is the entry point. The Goulds 3196 i-Frame gives you a moderate price point when you can supply the drive hardware. The Goulds 3196 XLT-X is the high-flow outlier with a much larger casing.
Price comparison
| Option | Price | Price bar | What it fits |
|---|---|---|---|
| Goulds 3196 STi 1x1.5-8 | $1,625 | Low-flow ANSI, ductile iron | |
| Goulds 3196 i-Frame 1x1.5-8 | $2,200 | Used 316SS, pump-only | |
| Goulds 3196LF 1x1.5-8 | $3,825 | New 316SS low-flow, big bore stuffing box | |
| Goulds 3196 XLT-X 8x10-15G | $6,500 | High-flow casing, 2,940 GPM |
Decision matrix
- Need high-volume transfer? The XLT-X is the only unit in this group with that flow class.
- Need a pump for chemical or high-purity service? The 3196LF is the low-flow option that fits that duty.
- Already have a motor and baseplate? The i-Frame gives you a lower price than the LF.
- Want the smallest cash outlay in this group? The STi is the lowest-priced pump.
Product notes
Goulds 3196LF

This is the only new pump in the group. The 316SS build covers the volute, impeller, shaft, and all wetted parts, which makes it a natural fit for chemical or high-purity service. The 1x1.5-8 low-flow configuration is compact, and the big bore stuffing box leaves room for packing or seal upgrades. At $3,825, it costs more than the other 1x1.5-8 pumps here, so it makes sense when new condition and full stainless wetted material justify the extra outlay. If your process doesn't need that level of assurance, a used unit can cover the same size range for less.
Goulds 3196 i-Frame

At $2,200, this used pump sits between the high-priced LF and the low-priced STi. The 316SS construction and 8-inch impeller are part of the package, and the 1x1.5-8 size puts it in the same pump family as the LF and STi. The biggest caveat is scope: this is pump only, with no motor, no baseplate, and no coupling included. That works in your favor if you're replacing a failed pump on an existing skid and can reuse the drive. If you're starting from scratch, remember that the total project cost will include those missing components, which can move the real price well above the $2,200 tag.
Goulds 3196 XLT-X

The nameplate for this used unit shows 2,940 GPM at 1,800 RPM with 144 ft of head, so it's clearly built for a different flow range than the 1x1.5-8 pumps. The 8x10-15G casing is the largest in the group, and the $6,500 price reflects the size of the hardware. The limitation is just as important: this is a pump casing/end, not a complete pump with motor and baseplate. That makes it a replacement part for someone who already owns a large drive. If your system doesn't need 2,940 GPM, the smaller options will be easier to justify on cost.
Goulds 3196 STi

The $1,625 price is the entry point for this entire group, and the STi still brings a proper 1x1.5-8 ANSI end-suction layout with a 6.75-inch impeller and 3,500 RPM rating. The material is the main trade-off: this is ductile iron, not 316 stainless steel. For water and many general industrial fluids, that can be a reasonable fit. For aggressive chemicals or high-purity process lines, the LF or i-Frame is a better material match. It's also a used pump, so factor the used condition into the lower price. If your service is compatible with iron, this is the lowest-cost way into the Goulds 3196 line.
Final recommendation by use case
- For chemical or high-purity service: choose the Goulds 3196LF.
- When you already have a motor and baseplate: choose the Goulds 3196 i-Frame.
- For high-flow transfer: choose the Goulds 3196 XLT-X.
- For the lowest entry cost in this group: choose the Goulds 3196 STi.
If your process fluid is aggressive, stick with the LF or i-Frame. If you're moving water or general industrial fluids, the ductile iron STi can keep the project cost down.
