The Wacker Neuson is a genuine OEM Diesel Fuel Pump designed for the HDR 115 Direct Fired Radiant Heater. Sourced directly from Wacker Neuson, this replacement pump meets the exact specifications of the original component installed at the factory. It is a direct-fit replacement for the HDR 115, ensuring correct fuel delivery pressure and flow characteristics without adaptation or guesswork. Keep your radiant heater running at peak output with a part built to the same standards as the one it replaces.
Key Features
- Correct Fuel Delivery Specification — Genuine OEM construction ensures this pump delivers fuel at the precise pressure and flow rate required by the HDR 115 burner assembly.
- Direct-Fit Replacement — Engineered to match original mounting points and fuel line connections on the HDR 115, allowing straightforward installation.
- Verified HDR 115 Compatibility — Confirmed fitment for the HDR 115 Direct Fired Radiant Heater (model HDR115_5100018592), so you order with confidence.
- Sustained Burner Performance — A properly functioning fuel pump maintains consistent combustion in the HDR 115; a worn or failing pump leads to erratic flame, heat output loss, or burner lockout.
- Fuel System Safety Assurance — As a critical fuel-circuit component, using a genuine OEM pump helps ensure the heater operates within its designed safety parameters and avoids fuel delivery faults.
The diesel fuel pump is responsible for drawing fuel from the tank and delivering it to the burner at a consistent, controlled pressure. In a direct-fired radiant heater like the HDR 115, steady fuel supply is essential for reliable ignition and stable heat output — any drop in pressure or flow will cause inconsistent combustion or prevent the unit from firing altogether. A worn or failed pump should be replaced promptly to restore safe, efficient heater operation.
