The Multiquip 50304 Pump P35/RW1800 is a genuine OEM hydraulic pump designed for RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF (up to serial number ). This is the factory-sourced pump assembly built to the exact specifications of the original unit, ensuring proper hydraulic flow, pressure output, and system compatibility. Sourced directly through Multiquip's authorized parts network, the 50304 is a direct match for the affected roller models and installs into the existing pump mounting position without modification. If your RAMMAX roller is showing sluggish drive response, inconsistent drum vibration, or hydraulic pressure loss, this pump assembly is the correct service replacement.
Key Features
- Genuine OEM Hydraulic Output: — Factory-sourced pump built to the same pressure and flow specifications as the original — no guesswork on hydraulic system compatibility.
- Direct-Mount Replacement: — Engineered to bolt directly into the existing pump mounting position on affected RAMMAX roller models using original hardware and porting.
- Confirmed Fitment: — Verified for RW1404, RW1404MR, and RW1504HF rollers up to serial number 1534188, including the RW1404MR from serial number 326075 and up.
- Restores Drive and Vibration Performance: — A worn or failing pump causes loss of hydraulic pressure, leading to reduced drum vibration output and sluggish propulsion — this OEM unit restores full system operation.
- Long-Term Hydraulic System Protection: — Using an OEM-spec pump prevents pressure mismatches that can accelerate wear on downstream hydraulic components such as motors, valves, and seals.
The hydraulic pump on a walk-behind roller like the RAMMAX RW series is the heart of the machine's drive and compaction system — it converts engine power into the hydraulic pressure that propels the roller and drives drum vibration. When the pump begins to wear or fails, the machine may exhibit reduced travel speed, weak or absent drum vibration, or difficulty maintaining consistent compaction passes. Replacing the pump with the correct OEM unit — in this case the Multiquip 50304 — ensures the hydraulic system operates within the designed pressure range, protecting the entire drivetrain and restoring the machine to full compaction capability.
