The Wacker Neuson 5100021682 is a genuine OEM Enclosure Box with Cover designed for the APT4, APT6, and APT8 series self-priming pump units. This includes skid-mounted (S) and towable (T) configurations, covering surge brake, electric brake, and Cold Weather variants across the full APT pump lineup. As a direct Wacker Neuson OEM part, the 5100021682 is built to the same specifications as the original component it replaces, ensuring a correct, hassle-free installation. Whether you are servicing a standard APT4S, an APT6T Electric Brake, or an APT8T Cold Weather unit, this enclosure box with cover is confirmed compatible across all major configurations in the APT series.
Key Features
- Genuine OEM Enclosure Integrity — Manufactured to Wacker Neuson's original dimensional and material specifications, ensuring the box and cover seat correctly and provide the same level of protection as the factory-installed unit.
- Correct Panel Access and Coverage — The integrated cover is designed to align precisely with the enclosure body, maintaining a secure closure over electrical or control components housed within the pump assembly.
- Broad APT Series Compatibility — Confirmed fitment across APT4, APT6, and APT8 series pumps in skid-mount and towable configurations, including standard and Cold Weather variants with surge brake or electric brake.
- Protects Critical Pump Components — A properly sealed enclosure shields internal wiring and controls from moisture, debris, and jobsite contamination — factors that can cause electrical faults or control failure if the housing is cracked or missing.
- Electrical Safety Compliance — On pump units with electric brake systems, a damaged or absent enclosure box can expose energized components. Replacing with a genuine OEM unit restores the original shielding and helps maintain safe operation.
The enclosure box with cover houses and protects the control or electrical components mounted on Wacker Neuson APT series pump units. It acts as a physical barrier against water ingress, dust, and mechanical damage — conditions that are common on active pump sites. When the enclosure box is cracked, broken, or missing its cover, the internal components are exposed to the elements, increasing the risk of electrical faults, corrosion, and control system failure that can take the pump unit out of service.
