The Wacker Neuson Water Pump is a genuine OEM component designed for the HI750GM, HI750GM HD, HI900DGM, and CUB700GM series diesel indirect-fired air heaters. Sourced directly from Wacker Neuson, this water pump meets the original engineering specifications for fluid circulation within the heater's hydronic circuit. It is confirmed compatible across multiple HI750GM and HI900DGM configurations, including surge brake and mobile genset variants, as well as the CUB700GM mobile indirect-fired air heater with genset.
Key Features
- Genuine OEM Fluid Delivery: — Manufactured to the original flow rate and pressure specifications required by Wacker Neuson indirect-fired heater systems — not a general-purpose pump adapted to fit.
- Drop-In Compatibility: — Engineered to mount and connect exactly as the original, with matching port sizing and bolt pattern for the HI750GM, HI900DGM, and CUB700GM heater platforms.
- Broad Fitment Across HI Series Heaters: — Covers HI750GM standard and HD mobile variants, HI900DGM surge brake and electrical configurations, and the CUB700GM diesel genset heater.
- Sustained Heat Output: — A properly functioning water pump maintains consistent coolant circulation through the heat exchanger; a failing pump leads to uneven heat distribution or full heater shutdown in cold-weather operations.
- Fuel System Safety Compliance: — As a fluid-circuit component in a diesel-fired heater, using the correct OEM pump ensures proper pressure regulation and helps prevent leaks or overheating events in the heating loop.
The water pump in a diesel indirect-fired air heater circulates heated fluid through the internal heat exchanger, allowing the unit to deliver consistent, clean warm air to the work area without exposing the airstream to combustion gases. In mobile heater applications like the HI750GM and HI900DGM series, this pump runs continuously during operation, making its condition directly tied to heating efficiency and output stability. When the pump wears or fails, circulation drops, heat output becomes inconsistent, and the heater may trigger thermal protection shutdowns — making timely replacement essential for uninterrupted cold-weather work.
