Why the 2 Inch AMT Replacement Diaphragm – Rubber (Model 336) Works Well for Clean-Water Jobs
When the job is straightforward and the water is relatively clean, there is no reason to pay more for neoprene or TPE. This 2″ rubber diaphragm gives you a reliable fit on the AMT Model 336 and keeps the pump running smoothly for dewatering, groundwater control, and light site drainage work.
Rubber flexes well in normal temperature conditions and creates a tight seal with each pump stroke. It is also the go-to material for contractors who do scheduled diaphragm replacements and want to keep parts costs predictable. Order a couple, keep one in the truck, and your Model 336 stays ready to go without burning through your parts budget.

Frequently Asked Questions
Q. What Pump Does This Rubber Diaphragm Fit?
The 2 Inch AMT Replacement Diaphragm – Rubber (Model 336) fits AMT 2″ Model 336 diaphragm pumps. Confirm your pump’s model number before ordering to make sure you get the correct part. A right-size diaphragm means a proper seal and full flow from the pump the first time you start it up.
Q. How Does Rubber Compare to Neoprene or TPE on the AMT Model 336?
Rubber is the most economical choice for clean water applications. It seals well and lasts a solid amount of time when the water is not abrasive or chemically active. Neoprene is better if your pump sees muddy, sandy, or mildly chemical water. TPE is the top pick for high heat or chemically aggressive pumping environments. Stick with rubber when the job is simple.
Q. How Long Does a Rubber Diaphragm Last on an AMT 2″ Pump?
In clean water use, most rubber diaphragms hold up for a year or more. If silt or fine grit gets into the water, plan on checking it more often since abrasion wears rubber down faster than neoprene. For daily use on dewatering jobs with reasonably clean water, rubber is a reliable choice. Having a spare in your parts kit keeps you covered when it is time to swap.
Q. Can I Order This Part by Part Number?
Yes. The 2 Inch AMT Replacement Diaphragm – Rubber (Model 336) is associated with AMT part number 3360-300-00. Use that number to cross-reference and confirm you have the right part. If you want to verify the fit for your specific pump before ordering, give us a call and we will help confirm it.
