Description
Overview:
The Diaphragm, Pump Walbr - Robin Part - RB147 62563 08 is a small engine pump diaphragm for the fuel system, typically used in Walbro-type carburettors fitted to Robin/Subaru petrol engines. Made from a flexible, fuel‐resistant elastomer, it transfers crankcase pulse energy to move fuel reliably from the tank into the carburettor. This helps maintain smooth running, easy starting, and steady idle under load. It is suitable for handheld garden tools and site machinery that use compact air‐cooled engines, such as brushcutters, hedge trimmers, water pumps, and generators. The diaphragm restores pump performance when the original part has stiffened, torn, or worn out through age or exposure to fuel and heat, helping to keep equipment dependable on site and in the garden.
Key Features:
- Fuel‐resistant elastomer construction for reliable operation with petrol and oil mix
- Maintains correct fuel delivery by converting engine pulse to consistent pump action
- Helps cure hard starting, stalling, and fuel starvation caused by a tired diaphragm
- Stable performance across typical small‐engine temperature ranges
- Sized for Walbro‐style pump sections used on many Robin/Subaru engines
- Smooth, flexible membrane for accurate response to pressure pulses
- Simple like‐for‐like replacement using basic hand tools
- Designed to fit within existing carburettor pump stack with correct thickness
- Supports efficient running and lower emissions through proper fuelling
- Cost‐effective service part to extend the life of your machinery
Typical Applications:
Used in the pump section of small engine carburettors on construction and garden machinery, including portable water pumps, generators, plate compactors, lawn mowers, brushcutters, hedge trimmers, and similar tools. Ideal when engines are slow to prime, surge at idle, or cut out under load due to weak fuel delivery.
Also known as:
Carburettor diaphragm, fuel pump diaphragm, carb pump membrane, impulse pump diaphragm, Walbro‐style pump diaphragm, small engine fuel diaphragm, carburettor pump membrane.
