The Bomag 05748689 Diaphragm Pump is a genuine OEM component designed for Bomag BT 60, BT 60/4, BT 65, BT 65/4, and BVT 65 tampers. Sourced directly from Bomag, this pump carries the same specifications as the original unit installed at the factory. This part delivers a direct, drop-in fit for the tamper models listed, restoring proper fuel delivery without guesswork on compatibility. If your tamper is exhibiting fuel starvation, hard starting, or inconsistent engine behavior, replacing the diaphragm pump with the correct OEM component is the right first step.
Key Features
- Genuine OEM Fuel Delivery Accuracy — engineered to the exact diaphragm thickness, port sizing, and stroke specification of the original pump, ensuring consistent fuel metering across the full RPM range of your tamper engine
- Direct Replacement Fit — mounts to the same bolt pattern and connects to the same fuel line ports as the original, with no reworking of brackets or fittings required
- Broad Tamper Coverage — fits the BT 60, BT 60/4, BT 65, BT 65/4, and BVT 65 tampers, covering multiple variants across the BT and BVT series
- Restored Engine Reliability — a failed or cracked diaphragm starves the engine of fuel at critical moments; this replacement restores steady fuel flow so the tamper delivers consistent compaction force on every stroke
- Fuel System Integrity — a properly functioning diaphragm pump maintains the correct fuel-to-air ratio and prevents unmetered fuel from entering the crankcase, protecting downstream engine components
The diaphragm pump is responsible for drawing fuel from the tank and delivering it at a consistent pressure to the carburetor or fuel system inlet of the tamper engine. It operates through the rhythmic flexing of a flexible diaphragm, which creates the suction and pressure strokes needed to move fuel without the need for an electric motor. When the diaphragm cracks, hardens, or develops a pinhole, fuel delivery becomes erratic or stops entirely — causing hard starting, rough running, or complete engine cutout during operation. Replacing a worn diaphragm pump with a genuine Bomag part number 05748689 restores predictable fuel flow and gets the tamper back to full compaction performance.
