The Wacker Neuson AC Pump is a genuine OEM AC Pump designed for the LTS4K, LTS7K, LTS8K, and LTE4K series light towers. Sourced directly from Wacker Neuson, this is the same part installed at the factory — ensuring a direct, correct-fit replacement with no guesswork on compatibility. It covers a broad range of configurations across the LTS and LTE families, including 50 Hz and 60 Hz variants, Metal Halide and LED lamp types, and both Trailer and Skid-mounted units. When your light tower's AC Pump fails, replacing it with the genuine OEM part keeps your equipment running to its original specification.
Key Features
- Genuine OEM Electrical Spec: — Built to Wacker Neuson's original output and voltage ratings, ensuring the pump operates within the correct electrical parameters for your light tower's system.
- Direct Drop-In Replacement: — Engineered to match the original mounting points and electrical connections of the 5100040970, so installation follows the same procedure as the factory-fitted unit.
- Broad LTS and LTE Series Fitment: — Compatible with LTS4K, LTS7K, LTS8K, and LTE4K light towers across 50 Hz and 60 Hz configurations, Metal Halide and LED lamp types, and Trailer and Skid-mounted builds.
- Sustained Tower Output: — A functioning AC Pump is essential for consistent power delivery within the light tower; a worn or failed pump can lead to loss of lighting output or system shutdown on the job.
- Electrical System Integrity: — Using the correct OEM-specified pump helps protect downstream electrical components from irregular load or voltage conditions caused by an undersized or mismatched replacement.
The AC Pump in a light tower is responsible for circulating or pressurizing fluid within the system to support the tower's power generation and lamp operation functions. It plays a direct role in maintaining consistent system performance — when this pump degrades or fails, the light tower may lose operational efficiency, experience overheating, or shut down entirely. Replacing it promptly with the correct OEM part restores full function and protects the broader system from secondary damage.
