When an industrial flow-control setup needs a pump, the biggest divide is often between pumping principles: peristaltic or centrifugal. Two used U.S.-built pumps, priced only about $40 apart, represent that divide clearly. The Cole Parmer Masterflex L/S uses a rotating pumphead with tubing to move fluid in four channels, while the Goulds 3196 STi uses an ANSI end-suction centrifugal design to move fluid through industrial process piping.
Quick verdict
If your process needs multi-line, low-shear fluid transfer where the fluid touches only the tubing, the Cole Parmer Masterflex L/S is the practical pick. If your process relies on an ANSI end-suction pump for continuous flow, the Goulds 3196 STi is the one to build around. The two pumps are close in price but far apart in how they move fluid.
Price and spec comparison
| Product | Listed Price | Pump Type | Key Spec |
|---|---|---|---|
| Cole Parmer Masterflex L/S with 4-channel pumphead | USD 1,585.00 | Peristaltic | Model 07575-50 with 7535-04 pumphead |
| Goulds 3196 STi 1x1.5-8 ANSI Pump | USD 1,625.00 | ANSI end-suction centrifugal | 6.75" impeller, 3,500 RPM |
Where the Cole Parmer wins
The Cole Parmer lets you run multiple tubing lines from one drive. That makes it useful for dosing, sampling, or feeding several process points while keeping the fluid path disposable. The peristaltic action also means the pump mechanism does not touch the fluid, which simplifies cleaning between product runs.
Where the Goulds wins
The Goulds is an ANSI end-suction centrifugal process pump. Its ductile iron construction and flood-oil bearing housing are practical for chemical and pulp-and-paper applications, where process pumps need to handle demanding fluids.
Product notes
Cole Parmer Masterflex L/S Peristaltic Pump
This Masterflex L/S package includes the 07575-50 process pump with a 7535-04 4-channel pumphead. For a multi-line operation, that means you can push several fluids simultaneously without buying multiple drives. Since the fluid stays inside tubing, cross-contamination is easy to contain and tubing changes are fast. The unit is sold as used in excellent working condition, which helps keep the entry price at USD 1,585.00. One limitation to weigh is that only the pictured components come with the pump. Plan around what is shown rather than assuming extra tubing or fittings are part of the sale.
Goulds 3196 STi ANSI Centrifugal Pump
This is a used Goulds 3196 STi pump in the 1x1.5-8 ANSI configuration, with a flood-oil bearing housing and ductile iron casing. The nameplate lists a 6.75-inch impeller at 3,500 RPM, which suits a process pump. It is priced at USD 1,625.00, but it is a completely different class of fluid mover. The practical limitation is that a centrifugal pump like this is not designed for precision multi-channel dosing. It is for process transfer, not for metering several small lines at once.
Final choice by use case
Choose the Cole Parmer Masterflex L/S if you need multi-channel, low-shear pumping with disposable tubing as the fluid path. Choose the Goulds 3196 STi if you need an ANSI end-suction process pump for industrial fluid handling in a process piping arrangement. With only $40 separating the prices, the decision should come down to your piping layout and pumping principle, not to cost.
