The Wacker Neuson 5200015254 is a genuine OEM Pump Diaphragm designed for the BS50-4As, BS60-4As, and BS70-4As vibratory rammers. As a direct OEM replacement, this part is manufactured to the same specifications as the original component installed at the factory, ensuring a correct fit across the full range of BS-series rammer configurations — including standard, high-altitude, and plastic shoe variants. The 5200015254 Pump Diaphragm is the right part to have on hand when servicing any of the supported BS50-4As, BS60-4As, or BS70-4As models, covering a broad range of configurations sold in the US and international markets.
Key Features
- OEM-Grade Diaphragm Material — Manufactured to original flex-fatigue and chemical-resistance specifications, ensuring the diaphragm maintains its pumping stroke integrity under sustained rammer operation.
- Drop-In Replacement — Matches the original mounting pattern and diaphragm diameter for the BS-series fuel pump assembly, allowing direct installation without modification.
- Broad BS-Series Compatibility — Fits BS50-4As, BS60-4As, and BS70-4As vibratory rammers across multiple machine configurations, including standard, high-altitude, and plastic shoe variants.
- Restores Consistent Fuel Delivery — A worn or cracked diaphragm disrupts fuel flow to the carburetor, causing hard starting, rough running, or stalling under load. Replacing it restores steady fuel delivery and consistent rammer performance.
- Fuel System Integrity — A compromised diaphragm can allow fuel to leak internally or externally within the pump assembly. Using the correct OEM part helps maintain a properly sealed fuel circuit.
The pump diaphragm is the flexible membrane inside the fuel pump that creates the pulsing action needed to draw fuel from the tank and deliver it to the carburetor at the correct pressure and volume. On a vibratory rammer like the BS50-4As, BS60-4As, and BS70-4As, this component is driven by crankcase pressure pulses generated during engine operation. Over time, the diaphragm can stiffen, crack, or develop pinholes, reducing fuel delivery and causing the engine to run lean, surge, or fail to start. Replacing the diaphragm at the first sign of fuel delivery issues is a straightforward repair that restores proper engine operation and prevents further carburetor or engine damage.
