The Wacker Neuson 5000051308 is a genuine OEM Rubber Diaphragm designed for the PDI3A, PDT3A, PDT3, PDI3, and PD3B series 75mm/3-inch diaphragm trash pumps. As a genuine OEM component, the 5000051308 is manufactured to the exact material grade and dimensional tolerances required by Wacker Neuson for consistent pump performance. This diaphragm is a direct-fit replacement, seating correctly in the pump housing without alteration. Verify your model number against the fitment list before ordering to ensure accurate application.
Key Features
- OEM-Grade Elastomer Material — Manufactured from rubber compound specified by Wacker Neuson to withstand the flex cycles and fluid exposure demands of continuous diaphragm pump operation.
- Direct-Fit Replacement — Sized and profiled to seat correctly within the pump chamber of compatible PDI3A, PDT3A, PDT3, PDI3, and PD3B pump housings, allowing straightforward installation.
- Broad PDx3 Series Compatibility — Covers multiple 75mm/3-inch inline and standard diaphragm trash pump configurations across the Wacker Neuson PD pump family.
- Restores Full Pumping Efficiency — A fresh diaphragm re-establishes the pressure differential needed for consistent fluid transfer; a cracked or fatigued diaphragm causes loss of prime, reduced flow, and pump failure.
- Genuine Wacker Neuson OEM Part — Supplied as part number 5000051308 directly within the Wacker Neuson parts catalog, ensuring you receive the correct specification for your pump model.
The rubber diaphragm is the core pumping element in a diaphragm-style trash pump. It flexes back and forth within the pump chamber, creating the suction and discharge pressure that moves fluid — including solids-laden water — through the pump body. Because the diaphragm is in constant motion and direct contact with pumped media, it is a wear item that will eventually crack, stiffen, or develop pinholes. When that happens, the pump loses prime, flow rate drops noticeably, or the pump fails to move fluid altogether. Replacing the diaphragm with a correctly specified part like the Wacker Neuson 5000051308 restores the pump to full working condition.
