The Wacker Neuson is a genuine OEM Water Manifold Complete designed for the WP1540 and WP1550 series single-direction vibratory plate compactors. As a factory-original component, it is manufactured to the same specifications as the part it replaces, ensuring a direct, hassle-free installation with no adaptation needed. Fitment covers the full WP1540 and WP1550 model range, including AW, A, V, VW, R, RW, and W variants, as well as wheel kit-equipped configurations. Keep this part number — — on hand for scheduled maintenance or field repairs to get your plate compactor back to work fast.
Key Features
- Factory-Original Construction: — Manufactured to Wacker Neuson OEM tolerances, ensuring the correct flow path geometry and port sizing for consistent water distribution across the compactor plate.
- Drop-In Replacement: — Matches the original mounting pattern and connection points on WP1540 and WP1550 series plates, allowing straightforward swap-out without reworking hose routing or hardware.
- Broad WP-Series Compatibility: — Fits the complete WP1540 and WP1550 family, including AW, A, V, VW, R, RW, and W variants, as well as models equipped with optional wheel kits.
- Sustained Water Coverage: — A fully functional water manifold delivers even water distribution across the plate surface, preventing asphalt and paving material from sticking during compaction passes. A cracked or blocked manifold leads to uneven wetting and surface buildup.
- Complete Assembly: — Supplied as a complete unit, so all internal passages and fittings are pre-assembled and ready to install — no sourcing individual sub-components separately.
The water manifold on a vibratory plate compactor distributes water evenly across the base plate to prevent bituminous and paving materials from adhering to the plate surface during asphalt compaction work. It acts as the delivery point for the machine's water sprinkler system, channeling flow from the onboard tank through a series of outlets along the plate width. When the manifold cracks, blocks, or leaks, water distribution becomes uneven or stops entirely, causing material to stick to the plate and compromising both the quality of the compacted surface and the efficiency of each pass.
