The Wacker Neuson 5200021625 is a genuine OEM Reservoir designed for the APT series towable trash pumps, covering the full range of APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T models — including standard, surge brake, electric brake, skid-mount, and cold weather configurations. As a direct factory replacement, this reservoir meets the same specifications as the original component installed at the time of manufacture. Whether you are servicing a standard pump or a cold weather variant, part number 5200021625 is the confirmed OEM-sourced component for the job. Cross-reference your machine number against the APT model family before ordering to ensure compatibility with your specific unit configuration.
Key Features
- Genuine OEM Fluid Integrity — Factory-sourced reservoir engineered to maintain correct fluid volume and pressure balance within the APT series hydraulic or fluid circuit, ensuring the system operates within its designed parameters.
- Broad APT Series Coverage — A single part number covers the APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T families, including skid-mount, surge brake, electric brake, and cold weather variants.
- Drop-In OEM Replacement — Matches the original mounting points and connection interfaces of the factory-installed unit, allowing straightforward swap-out during scheduled maintenance or field repair.
- Protects Downstream Components — A properly functioning reservoir maintains adequate fluid levels and prevents air ingestion, safeguarding pumps, seals, and associated assemblies from wear caused by dry or aerated operation.
- Cold Weather Configuration Compatible — Confirmed fitment across CW (cold weather) variants of the APT4T, APT6T, APT8S, APT8T, APT4S, and APT6S, making it a reliable stock item for year-round pump service needs.
The reservoir serves as the fluid storage and supply component within the APT series towable pump system, holding the hydraulic or operational fluid that supports braking, priming, or ancillary circuit functions depending on the specific model configuration. Keeping the reservoir in serviceable condition is essential to maintaining consistent fluid supply to connected components — a cracked, leaking, or degraded reservoir can starve the system of fluid, leading to erratic brake behavior, accelerated seal wear, or loss of operational pressure. Replacing a failing reservoir promptly with the correct OEM part helps restore the pump system to its intended operating state.
