Why the 2 Inch AMT Replacement Diaphragm – TPE (No Holes) Gives You the Best of Both Worlds
There are jobs where a pre-drilled diaphragm does not fit and a standard rubber blank is not tough enough. This 2″ TPE no-holes diaphragm solves both problems. You get the chemical and heat resistance of TPE in a blank format that adapts to your pump’s exact configuration.
It is a popular choice for repair shops and maintenance teams that work on a range of AMT 2″ pump variants and need flexibility in their parts inventory. The TPE material holds up after drilling and maintains its elasticity through repeated pump cycles in demanding environments. You are not giving up performance to get a custom fit.
Cross-Compatibility
The 2 Inch AMT Replacement Diaphragm – TPE (No Holes) is made for AMT 2″ diaphragm pumps that require a custom hole placement. If your AMT 2″ pump uses a standard bolt pattern, the pre-drilled Model 336 TPE version is the easier option. We also carry the 3″ no-holes TPE version and a neoprene no-holes version for the AMT 3″, along with the full range of standard diaphragms for other brands.
Frequently Asked Questions
Q. What Pump Is This No-Holes TPE Diaphragm For?
The 2 Inch AMT Replacement Diaphragm – TPE (No Holes) is designed for AMT 2″ diaphragm pumps that need a custom-drilled bolt pattern. Before ordering, measure your existing diaphragm carefully so you know exactly where to drill. If you are not sure whether your pump needs the no-holes version or the standard pre-drilled Model 336, give us a call and we will help you figure it out.
Q. How Does This Compare to the Standard AMT 2″ TPE Diaphragm with Holes?
The material and size are the same. The only difference is the absence of pre-drilled holes. If your pump uses the standard Model 336 bolt pattern, the pre-drilled version is faster to install. The no-holes version is for pumps with a different configuration or for cases where a custom hole pattern is required.
Q. How Does TPE Hold Up After Drilling Compared to Rubber?
TPE is more durable than rubber in heat and chemical conditions, and that advantage holds after drilling. As long as holes are placed correctly with clean cuts and proper spacing from the edges, the drilled diaphragm performs just as well as a pre-drilled part. Avoid drilling too close to the edge, which can cause tearing under pump pressure.
Q. Does This Come in Neoprene Without Holes?
Yes. A 3″ neoprene no-holes version for AMT pumps is available on our site. However, the 2 Inch AMT Replacement Diaphragm – TPE (No Holes) is currently the TPE option in the 2″ no-holes format. If you need a 2″ no-holes diaphragm in neoprene or rubber, call us and we can check current availability for your specific requirement.
