The Wacker Neuson Pump Kit is a genuine OEM component designed for the RD12A-90 and RD12-90 series tandem rollers, including Foldable ROPS and Solid ROPS configurations. Sourced directly from Wacker Neuson, this pump kit delivers the exact fit and internal specifications required to restore proper hydraulic function to your machine. Whether you're servicing an RD12A-90 or an RD12-90, part number is the correct OEM replacement to keep your roller performing to spec. Trust the factory-matched kit to eliminate guesswork and get your machine back in production.
Key Features
- Genuine OEM Internal Tolerances — Manufactured to Wacker Neuson's exact hydraulic specifications, ensuring correct pressure output and flow characteristics for the RD12 pump circuit.
- Drop-In Hydraulic Fit — Engineered to connect directly to existing hydraulic lines and mounting points on the RD12A-90 and RD12-90, with no improvised adapters or line modifications needed.
- Broad RD12 Series Coverage — Compatible with RD12A-90 and RD12-90 tandem rollers across Foldable ROPS and Solid ROPS variants, covering multiple machine configurations in one part number.
- Sustained Drive and Compaction Output — A healthy pump maintains consistent hydraulic pressure to the drum drives; a worn or failing pump leads to sluggish travel, uneven compaction force, and premature drivetrain stress.
- Hydraulic System Integrity — Using the correct OEM-rated pump kit helps maintain proper system pressure limits, reducing the risk of downstream component damage to valves, motors, and seals.
The pump kit supplies pressurized hydraulic fluid to the drive and vibratory systems of the RD12-series tandem roller, enabling both drums to deliver consistent compactive effort across asphalt and soil surfaces. When the pump wears or loses prime, hydraulic pressure drops, causing erratic drum speed, reduced compaction force, and potential overheating of the hydraulic circuit. Replacing the pump kit with the correct OEM assembly restores full system pressure and protects the downstream hydraulic components that depend on stable flow.
