The Wacker Neuson Pump is a genuine OEM component designed for the HI 120 and HI 120HD indirect-fired air heaters. Sourced directly from Wacker Neuson, this pump carries the same part number and specification as the original unit installed at the factory, ensuring a correct, like-for-like replacement. It is confirmed to fit both the HI 120 and HI 120HD models, making it the dependable choice when servicing either heater variant.
Key Features
- Genuine OEM Fuel Delivery Accuracy — Built to the exact flow and pressure specification of the original pump, maintaining proper fuel delivery to the burner assembly.
- Direct Drop-In Replacement — Matches the original mounting configuration and port connections on HI 120 and HI 120HD heaters for a straightforward swap.
- Confirmed Fitment — Verified for the HI 120 and HI 120HD indirect-fired air heater models.
- Consistent Burner Performance — A correctly functioning pump maintains steady fuel pressure, supporting reliable ignition and sustained heat output in cold-weather jobsite conditions.
- Fuel System Integrity — A worn or failing pump can cause erratic burner cycling, incomplete combustion, or heater shutdown; replacing it with a genuine OEM part restores proper fuel system operation.
The pump on an indirect-fired air heater is responsible for drawing fuel from the tank and delivering it at the correct pressure to the burner nozzle. Without consistent fuel flow, the burner cannot ignite properly or sustain the combustion needed to produce steady heat output. When the pump weakens or fails, operators typically see hard starting, intermittent flame lockouts, or a complete loss of heat — all of which point to fuel starvation at the burner. Replacing the pump with a genuine OEM part like the Wacker Neuson 5200024756 restores proper fuel delivery and gets the heater back to full heating capacity.
