The Wacker Neuson 5200021758 Housing is a genuine OEM component designed for the APT4, APT6, and APT8 series submersible pumps, including tow-behind and skid-mounted configurations with electric brake, surge brake, and cold weather variants. As a direct OEM replacement, this housing is manufactured to the same standards as the original part, ensuring a correct, drop-in fit across the full APT pump lineup. Fitment covers the APT4T, APT4S, APT6T, APT6S, APT8T, and APT8S series in both standard and cold weather configurations. Verifying your machine number against the fitment list before ordering is always recommended.
Key Features
- Genuine OEM Construction — Manufactured to original design tolerances, ensuring the housing maintains proper structural integrity and alignment for all internal pump components.
- Direct Drop-In Replacement — Matches the original mounting points and connection interfaces on APT series pumps, allowing straightforward installation without modification.
- Broad APT Series Coverage — Compatible with APT4, APT6, and APT8 pump families across tow-behind (T) and skid-mounted (S) variants, including all electric brake, surge brake, and cold weather configurations.
- Protects Critical Pump Internals — The housing encloses and aligns the pump's core working components; a cracked or damaged housing compromises both performance and water resistance, leading to accelerated internal wear.
- Sourced Direct from Wacker Neuson — Carries the OEM part number 5200021758, so you can confirm fitment with confidence against your machine's parts manual.
The housing forms the primary structural shell of the APT series submersible pump, enclosing and supporting internal components such as the motor, impeller, and seal assembly. It also serves as the main barrier between the pump's working internals and the surrounding environment, maintaining the watertight integrity essential for safe submersible operation. When a housing becomes cracked, corroded, or physically damaged, it can allow water ingress into protected areas, misalign internal components, and ultimately cause pump failure — making timely replacement critical to keeping the unit operating correctly.
