Choosing between used process pumps for industrial flow control starts with the pumping principle. The Cole-Parmer Masterflex L/S Process Peristaltic Pump and the Goulds 3196 i-Frame Centrifugal Process Pump take opposite approaches to moving liquids. One uses tubing and a peristaltic head; the other is a centrifugal pump built for process lines. The right choice depends on what you are moving, how you want to control the flow, and what you are willing to add around the pump.
Quick verdict
Choose the Cole-Parmer Masterflex L/S when you want tubing-based flow control and a peristaltic pump format. Choose the Goulds 3196 i-Frame when you need a centrifugal process pump for a line. Both are used units, so condition is part of the decision either way.

Where each product wins
Cole-Parmer Masterflex L/S Process Peristaltic Pump wins on upfront cost and tubing-based flexibility. At $1,585 it is $615 less than the Goulds, and the peristaltic format is the easier fit when your process is built around flexible tubing.
Goulds 3196 i-Frame Centrifugal Process Pump wins on process duty potential. The centrifugal design targets a different kind of flow than the peristaltic unit. At $2,200, you are paying for the pump core only.
Product notes
Cole Parmer Masterflex L/S Process Peristaltic Pump

The strongest reason to pick this used Masterflex L/S is the peristaltic format itself. A tubing-based pump gives you a different kind of flow control than a centrifugal unit, and the drive model 07575-50 is paired with a 7535-04 pumphead. The 60-day return warranty adds some confidence when buying used. The main limitation is that the unit includes all pictured components only, so you need to confirm that your tubing and fittings match this pumphead before you rely on it. If your flow task is tubing-based and you want a used pump that is ready to work with the components pictured, this is the more approachable choice. Just keep the peristaltic action in mind: it is not a substitute for a high-volume centrifugal pump.
Goulds 3196 i-Frame Centrifugal Process Pump

What sells the Goulds is the 316SS construction and the 8-inch impeller. Those details define a process pump, and the 3196 i-Frame designation puts it in the centrifugal process family. It is also a water-type pump from Canada, so if you are outfitting a process line that moves water-like fluids, this is the direction to go. The catch is that the unit is pump only: no motor, no baseplate, and no coupling are included. That means you have to supply the rest of the drive package before you can put it into service. The used condition also deserves a careful look at the impeller and casing. If you already have the motor and mounting hardware, the 316SS and 8-inch impeller make this the stronger pump for process duty.
Final choice by use case
If your application is tubing-based transfer, the Cole-Parmer Masterflex L/S is the more practical starting point. If your application is a water or process line that needs a centrifugal pump core, the Goulds 3196 i-Frame is the one to build around, as long as you can supply the motor, baseplate, and coupling.
