The Wacker Neuson Surge Absorber is a genuine OEM component designed for RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this part matches the original specification installed at the factory, ensuring a direct, hassle-free installation into your machine's hydraulic circuit. Confirmed fitment covers multiple RD27-100 and RD27-120 machine configurations, making it the reliable choice when you need an exact replacement for your tandem roller.
Key Features
- OEM Hydraulic Pressure Integrity — Manufactured to Wacker Neuson's original specification, maintaining the precise pressure-dampening characteristics required in the RD27 hydrostatic drive system.
- Direct Hydraulic Circuit Replacement — Engineered to seat and connect exactly as the original, allowing straightforward installation within the existing hydraulic circuit without additional adapters or modifications.
- Confirmed RD27 Series Fitment — Compatible with RD27-100 and RD27-120 hydrostatic vibratory roller configurations, covering a broad range of this tandem roller family.
- Protects System Components from Pressure Spikes — A functioning surge absorber shields pumps, motors, and valves from damaging hydraulic pressure fluctuations; a failed unit exposes the entire hydrostatic circuit to accelerated wear and potential failure.
- Hydraulic System Safety Assurance — Proper pressure management within the hydrostatic circuit is critical to safe, controlled roller operation; using a genuine OEM absorber ensures the system responds predictably under load.
A surge absorber — also known as a hydraulic accumulator or pulsation dampener — works within a machine's hydraulic circuit to absorb sudden pressure spikes and smooth out fluid flow. In a hydrostatic vibratory roller like the RD27 series, the drive system generates significant and rapid pressure changes during acceleration, deceleration, and directional shifts; without a properly functioning surge absorber, those pressure spikes travel through the circuit and subject pumps, motors, hoses, and valves to stress they are not designed to handle continuously. When the surge absorber degrades or fails, operators may notice erratic machine response, increased vibration in the hydraulic lines, or accelerated wear across connected components.
