Why the 2 Inch AMT Replacement Diaphragm – Neoprene (Model 336) Is Built for the Job Site
Neoprene has been a trusted diaphragm material in field conditions for decades. This 2″ AMT neoprene diaphragm stays flexible across a range of temperatures and holds up against the grit and debris that come with everyday mud pumping. It does not crack in cool morning temperatures or deform under the pressure of a pump running all day.
AMT Model 336 pumps are common on construction sites and dewatering jobs where the water is rarely clean. Neoprene suits that environment well, balancing durability with the flexibility needed for efficient pump cycles. Contractors who run their AMT pump through muddy, sandy, or mildly chemical water keep this diaphragm in their parts kit for fast swaps on the job.

Frequently Asked Questions
Q. What Pump Does This AMT Diaphragm Fit?
The 2 Inch AMT Replacement Diaphragm – Neoprene (Model 336) is built for AMT 2″ Model 336 diaphragm pumps. Always verify the model number on your pump before ordering to make sure you get the right fit. A proper-fitting diaphragm means a solid seal and pump output you can count on.
Q. How Does Neoprene Compare to Rubber or TPE for the AMT Model 336?
Neoprene is the middle-ground material for the Model 336. Rubber costs less and is fine for clean water jobs with minimal abrasion. Neoprene handles the muddy, sandy, and mildly chemical water that most AMT pump jobs involve. TPE is the premium choice when heat or strong chemicals are part of the picture. For most job site dewatering and mud pumping, neoprene is the right call.
Q. How Long Does This Neoprene Diaphragm Hold Up in Real Field Use?
Most contractors get six months to a full year of daily use out of a neoprene diaphragm on an AMT 2″ pump. If you are running it through coarse sand or abrasive slurry every day, expect to check it monthly. Neoprene holds up well compared to rubber in those conditions, but no diaphragm lasts forever in truly aggressive environments. Keeping a spare on hand is always a good idea.
Q. Can I Order This Part by Part Number?
Yes. The 2 Inch AMT Replacement Diaphragm – Neoprene (Model 336) crosses to AMT part number 3360-300-00. You can use that number to verify you have the right part before ordering. If you are searching by part number and want to confirm the fit, call us and we will double-check it against your pump model.
