The Wacker Neuson Pump is a genuine OEM component designed for the HDR 45, HD 50, HD 70, HI35, HI 90, and HI 90HD indirect-fired air heaters. Sourced directly from Wacker Neuson, this pump matches the original specification to ensure consistent fuel delivery performance across the full range of compatible HI and HDR series heaters. Correct fitment is confirmed for all six heater models, giving you confidence when ordering a direct replacement for a worn or failed unit.
Key Features
- Genuine OEM Fuel Delivery Spec — Manufactured to the exact flow rate and pressure output required by Wacker Neuson HI and HDR series indirect-fired heaters, maintaining consistent combustion performance.
- Drop-In Heater Replacement — Engineered to match the original mounting configuration and port connections, allowing straightforward installation without adaptation.
- Broad HI/HDR Series Compatibility — Confirmed fit for the HDR 45, HD 50, HD 70, HI35, HI 90, and HI 90HD indirect-fired air heaters in a single part number.
- Sustained Heat Output — A correctly functioning pump delivers steady, uninterrupted fuel flow to the burner; a worn pump causes inconsistent flame, reduced heat output, or hard starts in cold-weather applications.
- Fuel System Integrity — As a primary fuel-handling component on a fired heater, using a genuine OEM pump ensures correct pressure regulation and helps prevent fuel leaks or misfires at the burner assembly.
The pump on an indirect-fired air heater is responsible for drawing diesel fuel from the tank and delivering it at the correct pressure to the burner nozzle. Consistent fuel pressure is critical — too low, and the burner struggles to ignite or maintain a steady flame; too high, and combustion becomes inefficient or erratic. When this pump wears out, operators typically notice difficulty starting the heater, uneven heat output, or the unit cycling off unexpectedly. Replacing the 5200023883 pump restores proper fuel delivery and gets the heater back to full heating capacity.
