The Wacker Neuson Feed Pump is a genuine OEM component designed for RD25 hydrostatic double drum vibratory tandem rollers. Sourced directly from Wacker Neuson, this feed pump is manufactured to the exact tolerances and flow specifications required by the RD25 hydrostatic drive system. Confirmed fitment covers RD25 machines under model configurations and, making part number a direct, no-guesswork replacement for those units.
Key Features
- Genuine OEM Flow Specification — Manufactured to the precise pressure and volume output required by the RD25 hydrostatic circuit, ensuring the drive system receives consistent fluid supply.
- Direct-Fit Replacement — Engineered to match the original mounting configuration and port sizing of the RD25, allowing straightforward installation without system modification.
- Verified RD25 Compatibility — Confirmed fitment for RD25 hydrostatic double drum vibratory rollers, covering machine configurations 5000008058 and 5000009317.
- Hydrostatic System Integrity — A properly functioning feed pump maintains correct charge pressure across the hydrostatic loop, supporting smooth drum drive and consistent compaction output across both drums.
- Hydraulic System Safety — Inadequate feed pressure from a worn or failed pump can cause drive system cavitation and unpredictable machine behavior; replacing with a genuine OEM unit restores correct system protection.
The feed pump in a hydrostatic roller serves as the charge pump for the closed-loop hydrostatic transmission, supplying a constant flow of hydraulic fluid to maintain positive pressure within the drive circuit. This charge pressure prevents cavitation in the main hydraulic pump and motors, which is critical for smooth, controlled drum propulsion and braking on the RD25. When the feed pump wears or fails, charge pressure drops, leading to sluggish or erratic drive response, excessive heat buildup, and potential damage to the main hydrostatic components.
