Wacker Neuson 5000402517 Water System Kit

The Wacker Neuson is a genuine OEM Water System Kit designed for the WPU1550A, WPU1550Aw, WPP1550A, and WPP1550W reversible vibratory plate compactors. As a factory-sourced assembly, it delivers the correct components, tolerances, and material grades needed to restore the water sprinkling system to original operating condition. This kit covers the WPU and WPP 1550 series, making it a single, convenient solution for operators running either model on asphalt or paving stone applications. Keep part number on hand to minimize unplanned service interruptions during compaction work.

Key Features

• Genuine OEM Assembly: — Factory-sourced kit ensures every included component meets Wacker Neuson's original material and dimensional specifications for the water sprinkling system — no mismatched parts or improvised substitutes.
• Complete Kit Format: — Supplied as a matched set so all wetted components are replaced together, eliminating the risk of pairing a new pump or nozzle with a fatigued hose or fitting.
• Broad 1550 Series Coverage: — Confirmed fitment across the WPU1550A, WPU1550Aw, WPP1550A, and WPP1550W reversible plate compactors — covers both the standard and wet-kit variants in the 1550 family.
• Protects Surface Quality on Asphalt: — A properly functioning water system prevents the compactor base plate from sticking to hot-mix asphalt, preserving surface finish and allowing continuous forward progress on the mat.
• Straightforward Service Restore: — Designed to install using the existing mounting points and connections on the 1550 series frame, so the service technician can complete the repair without custom fabrication or additional hardware sourcing.

The water sprinkling system on a vibratory plate compactor continuously wets the base plate to prevent hot asphalt from adhering to the steel during compaction passes. Without a functioning water system, the plate will stick to the mat surface, tearing the asphalt and leaving an uneven, damaged finish. Over time, nozzles clog, hoses crack, and pump components wear — this kit replaces the critical elements of that system as a complete assembly, restoring consistent water distribution across the plate and allowing the compactor to work cleanly on asphalt and paving stone surfaces.
