The Wacker Neuson Water Tank is a genuine OEM component designed for WP1540 and WP1550 series single-direction vibratory plate compactors. As a direct factory replacement, it restores the water sprinkler system that prevents asphalt from sticking to the compaction plate during paving and surface work. This part fits a wide range of WP1540 and WP1550 variants — including AW, A, V, VW, RW, W, and R configurations — making it a versatile stock item for fleets running multiple machine builds. Sourced directly from Wacker Neuson, part number is manufactured to the same specifications as the original component it replaces.
Key Features
- Genuine OEM Construction: — Molded and finished to the same material grade and dimensional tolerances as the original tank, ensuring correct fluid capacity and leak-free performance in the water sprinkling system.
- Drop-In Fitment: — Mounts using the original attachment points on WP1540 and WP1550 plate compactors, with no modification to the frame or water system plumbing required.
- Broad WP-Series Compatibility: — Confirmed fit across WP1540, WP1540A, WP1540AW, WP1540W, WP1550, WP1550A, WP1550AW, WP1550V, WP1550VW, WP1550R, WP1550RW, and WP1550W variants, including wheel-kit equipped models.
- Restores Asphalt Release Function: — A cracked or failed water tank starves the sprinkler system, causing hot asphalt to bond to the baseplate and interrupting the compaction pass. Replacing it promptly keeps surface work on schedule.
- Verified Part Number: — Cross-referenced to Wacker Neuson OEM catalog as 5000401209, eliminating guesswork when ordering for mixed-variant fleets.
The water tank on a vibratory plate compactor feeds the integrated water sprinkler system, which continuously wets the bottom of the compaction plate during asphalt work. This thin film of water prevents sticky bituminous material from adhering to the plate, allowing smooth, consistent passes without surface tearing or plate buildup. When the tank cracks, leaks, or fails entirely, the sprinkler system runs dry and the plate begins to drag and stick — compromising surface finish and forcing operators to stop and clean the equipment manually.
