The Wacker Neuson 5200019989 Intake Gasket is a genuine OEM intake gasket designed for the APT4T and APT4S series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this gasket is confirmed to fit multiple APT4T and APT4S configurations, including electric brake, surge brake, and cold weather variants. As a genuine OEM component, part 5200019989 is manufactured to the exact material and dimensional specifications of the original part installed at the factory. Verify your model number before ordering to ensure a correct, direct fit.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same material compound and compression spec as the original gasket, delivering an airtight seal at the intake port under continuous pump operation.
- Direct Drop-In Installation — Matches the original bolt pattern and flange profile of the APT4T and APT4S pump housings, seating cleanly without trimming or modification.
- Broad APT Series Fitment — Compatible across APT4T (electric brake, surge brake) and APT4S (w/Skid) models, including cold weather variants, covering a wide range of configurations within the APT pump family.
- Sustained Prime and Flow Efficiency — A sound intake gasket maintains the vacuum seal needed to prime the pump and hold suction; a cracked or compressed gasket causes air leaks that starve flow and force the pump to lose prime under load.
- Fuel and Fluid Compatibility — Designed to resist degradation from water, slurry, and the debris-laden fluids these trash pumps routinely handle on site.
The intake gasket forms the sealing interface between the intake port and the pump housing, preventing air from entering the suction side of the system. A properly sealed intake is essential for the pump to generate the vacuum required to draw fluid into the impeller — even a minor air leak at this joint can cause the pump to lose prime, run dry, or deliver inconsistent flow. When the gasket compresses, cracks, or tears, the first signs are typically difficulty priming, reduced output, or the pump failing to self-prime entirely.
