The Wacker Neuson TPE Diaphragm is a genuine OEM component designed for the PDT2, PDT2A, PDT2B, PDI2, and PDI2A series 50mm/2in diaphragm trash pumps. Sourced directly from Wacker Neuson, this replacement diaphragm matches the exact material grade and dimensional specification of the original part. Correct fitment is confirmed across both standard and inline diaphragm pump configurations in this family, making the a straightforward service replacement for operators and technicians alike.
Key Features
- TPE Material Construction — Thermoplastic elastomer construction delivers the flexibility and chemical resistance required for diaphragm pump service, maintaining a reliable seal through repeated flex cycles.
- Genuine OEM Part — Supplied by Wacker Neuson as original equipment, ensuring the diaphragm meets the pressure rating and stroke geometry the pump was engineered around.
- Broad PDT2 and PDI2 Series Coverage — Compatible with PDT2, PDT2A, PDT2B, PDI2, and PDI2A models, covering both standard diaphragm and inline diaphragm trash pump variants in the 50mm/2in class.
- Restores Full Pumping Capacity — A worn or cracked diaphragm causes loss of prime, reduced flow, and fluid bypass; replacing with part 5000089595 restores the pump's rated discharge performance.
- Direct-Fit Service Replacement — Mounts in the same position as the original diaphragm with no rework to the pump head or valve assembly required.
The diaphragm is the primary pumping element in a diaphragm-style trash pump. As the diaphragm flexes back and forth, it creates the pressure differential that draws fluid in through the inlet valve and forces it out through the discharge valve. Because the diaphragm is in constant contact with the pumped fluid and subject to continuous mechanical flexing, it is one of the highest-wear components in the pump. When the diaphragm develops cracks, pinholes, or loses elasticity, the pump loses the ability to maintain prime and output pressure drops significantly — or stops altogether. Replacing the diaphragm promptly with a correctly rated part like the Wacker Neuson 5000089595 returns the pump to full service condition.
