When you're comparing pumps for industrial pumps flow control, the first fork in the road is usually pump architecture. The Cole Parmer Masterflex L/S is a process peristaltic pump, while the Goulds 3196LF is a low-flow ANSI process pump. They're $2,240 apart: $1,585 for the Masterflex and $3,825 for the Goulds. That gap is large, but it's not the only difference that matters.
Quick Verdict
If you want a flexible, tubing-based pump and can accept a pre-owned unit, the Cole Parmer Masterflex L/S is the practical, lower-cost route. If you want a new process pump ready for chemical or high-purity service, the Goulds 3196LF is the more direct fit.
Masterflex L/S vs Goulds 3196LF at a Glance
| Product | Price | Price Bar | Condition | Key Specs |
|---|---|---|---|---|
| Cole Parmer Masterflex L/S | $1,585.00 | Used | Process peristaltic pump with 4-channel pumphead | |
| Goulds 3196LF | $3,825.00 | New | Low-flow ANSI process pump, 316SS wetted parts, big bore stuffing box |
Where Each Product Wins
The Cole Parmer Masterflex L/S wins when the lower price and a peristaltic setup are the priority. Its tubing-based design suits operations that want to change the fluid path quickly.
The Goulds 3196LF wins when you want a new pump rather than a used one. It's priced higher, but it comes as a fresh ANSI pump ready for process service.
Product Notes
#### Cole Parmer Masterflex L/S Process Peristaltic Pump with 4-Channel Pumphead
This is the pump to put on your shortlist when you want multiple flow paths from one unit. The included 4-channel pumphead lets you handle up to four tubes at once, making it a practical option for applications that need to move fluid through several lines. Because it's a peristaltic pump, the fluid path is the tubing itself. The trade-off is that this is a used unit and only the pictured components are included, so you're getting the pump and pumphead as shown rather than a full accessory package. The 60-day return warranty gives you a defined window to assess it. If your priority is the lower upfront cost, this is the pump to weigh.
#### Goulds 3196LF 1x1.5-8 Process Pump 316SS
The Goulds is a new process pump aimed at low-flow service. Its 316 stainless steel construction extends to the volute, impeller, shaft, and all wetted parts, which makes it suited for chemical and high-purity service. The big bore stuffing box is a meaningful detail, ideal for packing or seal upgrades. The trade-off is the higher upfront cost compared to the used Masterflex; you're paying for a new pump with a full metal wetted path. If your process demands low-flow performance and 316SS materials, this Goulds is the direct fit.
Final Choice by Use Case
For a lower-cost peristaltic setup that's comfortable to run through tubing, the Cole Parmer Masterflex L/S is the pick. For an ANSI process pump that's ready for service, the Goulds 3196LF is the pick. Match those two directions to your process and the decision becomes clearer.
