The Wacker Neuson Base is a genuine OEM component designed for the APT4S and APT4T series transfer pumps, including standard, surge brake, electric brake, and cold weather configurations. As a direct OEM part sourced from Wacker Neuson, it is manufactured to the same specifications as the original, ensuring a consistent, accurate fit across all covered pump variants. This Base is compatible with both APT4S Pump with Skid and APT4T Pump models, spanning the full range of standard and cold weather builds. Keeping the correct base in service is essential to maintaining the structural integrity and proper positioning of the pump assembly.
Key Features
- Genuine OEM Construction — Produced by Wacker Neuson to original design tolerances, so the base provides the same load-bearing support and mounting geometry as the part it replaces.
- Drop-In Replacement — Matches original mounting points and attachment hardware on APT4S and APT4T pump assemblies, fitting without rework or modification to the frame.
- Broad APT Series Coverage — Fits six pump configurations across the APT4S and APT4T families, including surge brake, electric brake, and cold weather variants.
- Structural Platform Integrity — A sound base keeps the pump unit properly seated and level; a cracked or deteriorated base can cause misalignment of connected components and accelerate wear elsewhere in the assembly.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5200019907, cross-referenced against all six listed model and configuration numbers.
The base serves as the primary structural foundation of the pump assembly, supporting the pump unit and providing the mounting surface that keeps all connected components correctly aligned during operation. A properly functioning base distributes the weight and operational forces of the pump evenly, preventing unwanted movement or vibration that could stress fittings, hoses, and drive components. When the base becomes cracked, corroded, or physically compromised, it can allow the pump to shift out of position, leading to premature wear on attached parts and potential interruption of pumping operations.
