When you're setting up or upgrading an industrial pumps flow control system, the pump choice often comes down to cost versus condition. Two strong contenders in the process pump space are the Goulds Pump 3196-4X6-10G and the 3" x 2" Durco Flowserve MK3 STD. We're putting them head to head to help you decide which one deserves a spot in your process line. The Goulds is a used workhorse that keeps the initial cost low, while the Flowserve is a new open-box pump that brings a higher specification to chemical process lines. The decision hinges on whether you're okay with a pre-owned pump to save money or you need the reliability of a new unit in a chemical process environment.
Quick Verdict
If you want a capable process centrifugal pump without stretching your equipment budget, the used Goulds 3196-4X6-10G is the practical pick. If you'd rather spend more for a new open-box unit with a chemical process design and higher pressure rating, the Flowserve MK3 STD is the stronger investment.

Where Each Pump Wins
- Goulds 3196-4X6-10G wins on price and straightforward process-pump simplicity. Its used condition means it's the more accessible option for a standard process duty.
- Flowserve MK3 STD wins on being a new open-box unit with a chemical process specification, including a higher pressure rating and DCI material build. It's the more feature-rich choice if your application demands those parameters.
In short, your choice depends on whether you prioritize upfront cost or a new, more highly rated unit.
Goulds Pump 3196-4X6-10G: The Lower-Cost Workhorse
At $1,167.60, the Goulds Pump 3196-4X6-10G is a lower-cost process centrifugal pump from Goulds Pump, with a '4X6-10G' frame designation that fits many standard industrial pump layouts. The condition is used, so it's a pre-owned option that can handle typical process flow control duties. A two-year coverage plan is included in the purchase price, giving it a layer of protection despite the used state. The main limitation is that used equipment inherently carries more uncertainty about remaining service life compared to a new unit. If you want a straightforward process pump without a big capital outlay, this is the sensible pick.
3" x 2" Durco Flowserve MK3 STD: The New Chemical Process Option
The 3" x 2" Durco Flowserve MK3 STD is a new open-box chemical process pump with a 3-inch by 2-inch port configuration, built with DCI material and rated for 250 PSI at 100°F. It's the higher-priced option, but you're getting a surplus unit that has never been in service, so there's no wear to account for. The 315-pound weight signals a heavy-duty build suited for demanding process lines. The trade-offs are the larger upfront investment and the fact that pumps cannot be tested before sale; however, a money-back guarantee applies if the unit arrives dead on arrival. This is the pump to choose when your flow control setup requires a new unit with specific chemical process ratings.
Final Choice by Use Case
For a standard process pump application where keeping costs down is key, the Goulds Pump 3196-4X6-10G is the sensible choice. For a chemical process environment that demands a new pump with higher pressure capability and a material spec designed for chemicals, the 3" x 2" Durco Flowserve MK3 STD is worth the extra investment.
