The Wacker Neuson is a genuine OEM Suction Charge Pump Hose designed for the RD12A-90 series tandem rollers, including the standard Tandem Roller, the Double Drum Green configuration, and the Tandem Roller with Foldable ROPS. As a factory-sourced component, the is manufactured to the exact specifications required by Wacker Neuson for these machines, ensuring a direct, hassle-free installation. If your RD12A-90 is showing signs of hydraulic charge pump issues — such as sluggish drum drive response or visible fluid loss — this is the correct hose to restore full system integrity. Confirm your model number against the fitment list below before ordering to guarantee accuracy.
Key Features
- OEM-Grade Hose Construction — Built to Wacker Neuson's pressure and flexibility specifications for charge pump circuits, delivering the wall thickness and reinforcement needed to handle hydraulic working pressures in this roller platform.
- Drop-In Replacement for RD12A-90 Rollers — Engineered to connect at the same ports and routing path as the original hose, so installation follows the standard service procedure without rework or adaptation.
- Covers All RD12A-90 Configurations — Fits the RD12A-90 Tandem Roller, RD12A-90 Double Drum Green, and RD12A-90 Tandem Roller with Foldable ROPS, covering the full range of this machine family.
- Maintains Charge Pump Flow Integrity — A sound suction hose keeps the charge pump primed and delivering consistent hydraulic flow to the drive circuit; a cracked or collapsed hose starves the pump and causes erratic or complete loss of drum propulsion.
- Fuel System Safety Compliance — Using the correct OEM hose in the hydraulic circuit ensures the assembly meets the original design intent, reducing the risk of uncontrolled fluid release on an active compaction site.
The suction charge pump hose draws hydraulic fluid from the reservoir into the charge pump, which maintains the minimum pressure needed to keep the closed-loop drive circuit primed and responsive. Without adequate suction, the charge pump cannot sustain the pressure required for smooth, controlled drum movement — leading to hesitation, overheating, or full drive failure. Replacing a worn, kinked, or cracked hose promptly protects the charge pump and the downstream hydrostatic components from damage caused by cavitation or fluid starvation.
