2″ AMT Replacement Diaphragm – TPE (Model 336)

The 2 Inch AMT Replacement Diaphragm – TPE (Model 336) is the right choice for contractors who push their AMT Model 336 pump in high-heat or chemically demanding conditions. TPE outlasts rubber and neoprene when the pumping environment gets aggressive, and this replacement diaphragm delivers that same performance in a direct-fit format for the AMT 2″ Model 336 pump. It installs without modification and gives you a longer service interval when the job is hard on parts. Order it when standard materials are not holding up.

Key Features

Why the 2 Inch AMT Replacement Diaphragm – TPE (Model 336) Outperforms Standard Materials

TPE is engineered to take on the kind of stress that standard rubber and neoprene cannot handle for long. In environments where temperatures climb, where the fluid carries solvents or industrial chemicals, or where the pump runs continuously for extended shifts, this 2″ TPE diaphragm stays elastic and keeps a tight seal.

The AMT Model 336 is used in a wide range of settings, from basic dewatering to industrial fluid transfer. When the job leans industrial, TPE is the material to spec. It flexes consistently across a much wider temperature range and resists chemical absorption that causes other materials to swell, crack, or lose their shape. Paying a little more for TPE on a demanding job saves you the cost of an emergency repair.

Cross-Compatibility

The 2 Inch AMT Replacement Diaphragm – TPE (Model 336) is made for AMT 2″ Model 336 diaphragm pumps. If your conditions are less demanding, rubber and neoprene versions for the Model 336 are listed on separate pages. We also carry TPE diaphragms for the AMT 3″ Model 335 and no-holes TPE versions, plus a full range of AMT-compatible parts and diaphragms for CH&E, Magnum, Mud Hog, Wacker, Gorman-Rupp, Multiquip, and Riverside pumps.

Frequently Asked Questions

Q. What Pump Does This TPE Diaphragm Fit?

The 2 Inch AMT Replacement Diaphragm – TPE (Model 336) fits AMT 2″ Model 336 diaphragm pumps. Always confirm the pump model number and the correct diaphragm size before ordering, especially when you are working with industrial or chemical pumping setups where a wrong fit can cause immediate problems.

Q. How Does TPE Compare to Rubber and Neoprene for the AMT Model 336?

Rubber is the economy pick for clean, low-demand water. Neoprene handles mud and mild chemicals well for most construction-site pumping. TPE steps in when neither of those is enough. It performs best in high heat, strong chemical exposure, or continuous-run industrial environments where diaphragm failure has real consequences. If you are burning through neoprene, TPE is the next step up.

Q. How Much Longer Does a TPE Diaphragm Last Compared to Rubber?

In heat and chemical conditions, TPE can last significantly longer than rubber, sometimes two to three times as long depending on the environment. The key advantage is that TPE does not absorb chemicals or soften from sustained heat the way rubber does. For industrial pump applications that run daily, TPE pays for its higher price in reduced replacement frequency.

Q. Can I Order This Part by Part Number?

Yes. The 2 Inch AMT Replacement Diaphragm – TPE (Model 336) is associated with AMT part number 3360-300-00. You can use that number to cross-reference and verify the part before ordering. If you want to confirm the fit or check stock availability, call us and we will take care of it for you.
