The Wacker Neuson RD12 Pump Seal Kit is a genuine OEM seal kit designed for the RD12-90 and RD12A-90 series tandem rollers. As a direct OEM replacement, this kit ships with every seal needed to restore the hydraulic pump to proper operating condition — no sourcing individual components separately. It fits all major RD12-90 and RD12A-90 configurations, including solid ROPS, foldable ROPS, and green-drum variants. Keep part number on hand as a service spare to stay ahead of scheduled pump maintenance.
Key Features
- Genuine OEM Sealing Materials — Wacker Neuson-sourced seals are manufactured to the correct durometer and compound spec for hydraulic pump service, ensuring proper compression and fluid retention under operating pressure.
- Complete Kit Format — All seals required for a full pump rebuild are included in a single kit, eliminating the guesswork of ordering individual seal sizes.
- Broad RD12 Family Fitment — Confirmed fit across RD12-90 and RD12A-90 tandem roller configurations, including solid ROPS, foldable ROPS, and double-drum green variants.
- Hydraulic Integrity Restored — Worn or extruded pump seals cause internal bypass, pressure loss, and sluggish drum drive response; replacing them with 5200008527 restores full hydraulic output and smooth compaction performance.
- Hydraulic System Safety — Compromised pump seals can lead to uncontrolled pressure loss in the drive circuit; using the correct OEM seal kit maintains predictable machine response and operator control on grade.
The hydraulic pump seal kit contains the internal sealing elements that prevent fluid from bypassing or leaking within the pump assembly on the RD12 tandem roller. These seals maintain the pressure differential the pump needs to drive the drum motors and propulsion circuit effectively. When seals wear, crack, or extrude, the pump loses volumetric efficiency — symptoms typically include slow or uneven drum drive, reduced compaction force, and visible hydraulic fluid loss. Replacing the seal kit at the first sign of these symptoms restores pump performance and prevents more costly pump or motor damage downstream.
