Key Features
- Genuine OEM Fuel Delivery Accuracy — Manufactured to Wacker Neuson's precise flow and pressure tolerances, ensuring correct fuel injection output critical to consistent burner performance.
- Direct Drop-In Replacement — Engineered to match the original pump mounting configuration and connection points on the HSH700 and HSH650, supporting a straightforward service installation.
- Confirmed HSH Series Fitment — Verified for the HSH700 and HSH650 hydronic surface heaters; always cross-reference your machine's model number before ordering.
- Restores Full Heating Output — A correctly functioning injection pump maintains the steady fuel supply the burner needs to reach and hold target temperatures across the heating circuit.
- Fuel System Integrity — As a fuel-system component, using the correct OEM-specification kit helps maintain proper sealing and rated operating pressures, reducing the risk of fuel leaks or uncontrolled combustion behavior.
The injection pump is responsible for drawing fuel from the tank and delivering it to the burner at the correct pressure and flow rate. In a hydronic surface heater like the HSH700 or HSH650, consistent fuel injection is essential — the burner relies on a steady, metered supply to heat the fluid that circulates through the heating hoses and ground-contact blankets. When the injection pump wears or fails, the burner may struggle to ignite, run erratically, or shut down entirely, leaving the heating system unable to maintain the temperatures required for concrete curing or frost protection. Replacing the pump with the genuine Wacker Neuson 5000176545 kit restores the system to its correct operating condition.
