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 is manufactured to the same material and dimensional standards as the original, ensuring a proper drop-in fit within the pump head assembly. It covers both standard and inline diaphragm pump configurations across the 2-inch family, making it a versatile stocking part for crews running multiple pump models on site.
Key Features
- TPE Material Construction — Thermoplastic elastomer delivers the flexibility and chemical resistance required to maintain a consistent pumping stroke under continuous fluid cycling.
- Genuine OEM Part — Manufactured to Wacker Neuson's original specification, ensuring correct thickness, durometer, and port geometry for a sealed, leak-free installation.
- Broad 2-Inch Pump Family Coverage — A single part number fits PDT2, PDT2A, PDT2B, PDI2, and PDI2A models, covering both standard and inline configurations in the 50mm/2in diaphragm trash pump lineup.
- Restores Full Pump Output — A worn or cracked diaphragm causes loss of prime, reduced flow, and fluid bypass; replacing it with part 5000089595 returns the pump to its rated discharge capacity.
- Critical Fluid-Containment Component — The diaphragm is the primary barrier between the fluid chamber and the pump mechanism; a failed diaphragm can allow pumped media to contaminate internal components, leading to accelerated wear throughout the pump head.
The diaphragm is the heart of a diaphragm-style trash pump. It flexes back and forth in a reciprocating motion to draw fluid in through the inlet valve and push it out through the discharge valve, creating flow without relying on centrifugal force. This design allows the pump to handle slurries, sludge, and debris-laden water that would damage other pump types. When the diaphragm cracks, stiffens, or develops a pinhole, the pump loses its ability to build suction and move fluid efficiently — symptoms that often appear as slow priming, pulsating output, or complete loss of flow. Replacing the diaphragm promptly with the correct OEM part restores pumping performance and protects the valves and housing from secondary damage.
