2 Inch AMT Replacement Diaphragm – TPE (Model 336) is designed for AMT 2 inch Model 336 diaphragm pumps operating in demanding dewatering, industrial, and fluid-transfer applications. The TPE construction provides excellent flex fatigue resistance and durability for applications where frequent pump cycling, outdoor operation, or challenging fluids place additional stress on the diaphragm.

This replacement diaphragm is a strong option when your AMT Model 336 requires a TPE diaphragm rather than a standard rubber or neoprene material. Always confirm the pump model, required diaphragm material, fluid being handled, and operating conditions before ordering.

  • Common Applications: Construction dewatering, industrial pumping, groundwater removal, and selected demanding fluid-transfer applications

Why Choose a TPE Diaphragm for an AMT Model 336?

TPE diaphragms are commonly selected for applications where fatigue resistance, repeated flexing, and longer service intervals are important. The material combines rubber-like flexibility with the durability of a thermoplastic elastomer, making it useful for selected demanding pump applications.

For an AMT Model 336 operating for extended periods or under challenging service conditions, TPE may provide advantages over general-purpose diaphragm materials. Actual service life depends on the fluid being pumped, temperature, operating hours, pump condition, installation, and maintenance practices.

TPE should not be selected solely because it is considered a more durable material. Confirm that it is appropriate for the specific fluid and operating conditions before replacing another diaphragm material.

Common Applications

This AMT Model 336 TPE replacement diaphragm may be used in applications such as:

  • Construction and excavation dewatering
  • Groundwater removal
  • Industrial water transfer
  • Continuous or high-cycle pump operation
  • Selected slurry and wastewater applications
  • Applications where diaphragm fatigue resistance is a priority

If the pump will handle chemicals, petroleum products, unusual temperatures, or other demanding fluids, confirm material suitability before ordering.

Signs Your AMT Model 336 Diaphragm May Need Replacement

Inspect the diaphragm when pump performance changes or during routine service. Common signs of diaphragm wear include:

  • Longer priming time
  • Reduced suction
  • Lower discharge flow
  • Irregular pump operation
  • Visible cracking, thinning, stiffening, or deformation
  • Leakage around the diaphragm housing

A damaged diaphragm should be serviced promptly. Continuing to operate the pump with a deteriorated diaphragm can reduce performance and may contribute to additional wear inside the pump.

Installation and Maintenance

Confirm that the pump is an AMT Model 336 and that TPE is the appropriate diaphragm material for the application before installation.

  • Clean the diaphragm housing and sealing surfaces before installing the replacement.
  • Compare the replacement diaphragm with the original AMT Model 336 diaphragm before assembly.
  • Inspect valves and other wear components while the pump is disassembled.
  • Tighten mounting hardware evenly according to the AMT service procedure.
  • Flush the pump after handling slurry, sediment, or fluids that may leave deposits inside the housing.
  • Inspect the diaphragm regularly according to operating conditions and pump usage.

Frequently Asked Questions

What pump is this TPE diaphragm for?

This replacement diaphragm is intended for the AMT 2 inch Model 336 diaphragm pump. Confirm the complete AMT pump model before ordering.

Why choose TPE instead of rubber or neoprene?

TPE may be selected when fatigue resistance, high-cycle operation, or demanding service conditions are important. Rubber and neoprene remain useful materials for many water and construction applications, so the appropriate material depends on the pump requirements and fluid being handled.

Can I change from rubber or neoprene to TPE?

Do not select a different diaphragm material based only on size or appearance. Confirm the AMT Model 336 requirements, fluid type, operating conditions, and recommended diaphragm material before changing compounds.

Is TPE appropriate for chemical pumping?

TPE can be suitable for selected fluids, but suitability varies according to the specific chemical, concentration, temperature, and operating conditions. Confirm the fluid requirements before ordering a diaphragm for chemical service.

How long will a TPE diaphragm last?

Diaphragm life varies according to pump usage, fluid abrasiveness, temperature, operating hours, installation, and maintenance. TPE is often selected for demanding or high-cycle applications, but there is no single service-life multiplier that applies to every AMT Model 336 pump.

Can I order this AMT diaphragm in quantity?

Yes. Ken’s Distributing offers bulk and blanket order programs for qualifying contractors, rental operations, distributors, and businesses maintaining multiple diaphragm pumps. Contact Ken’s Distributing with your quantity and purchasing requirements for pricing information.
