The Multiquip 50326 is a genuine OEM Vibration Pump RW-3015 designed for MVH508DZ reversible plate compactors and RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF. As a direct Multiquip OEM part, 50326 meets the original engineering specifications for these machines, ensuring correct hydraulic output and vibration performance. This part is confirmed to fit RW1404MR units at serial number 326075 and up, as well as RW1504HF units up to serial number — verify your serial number range before ordering to confirm compatibility.
Key Features
- Genuine OEM Hydraulic Specification — Built to the exact flow and pressure ratings required by the vibration system on these compactors and rollers, with no guesswork on output performance.
- Direct-Fit Replacement — Engineered to mount and connect to the existing hydraulic circuit without alteration, using the same port configuration as the original pump.
- Broad Cross-Family Fitment — Confirmed for MVH508DZ, RW1404, RW1404MR, and RW1504HF equipment, covering both reversible plate compactor and walk-behind roller applications.
- Serial Number-Specific Compatibility — Fitment is validated for RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N 1534188), so you can order with confidence when your machine falls within the correct range.
- Sustained Compaction Force — A correctly functioning vibration pump maintains consistent hydraulic pressure to the vibration mechanism; a worn or failing pump results in reduced compaction force and uneven surface results.
The vibration pump is the hydraulic heart of the compaction and vibration system on reversible plate compactors and walk-behind rollers. It generates and sustains the pressurized hydraulic flow that drives the eccentric weight or vibration assembly, producing the compaction force the machine delivers to the surface. When this pump wears or fails, hydraulic pressure drops, vibration output weakens, and compaction effectiveness decreases significantly — leaving material under-compacted and potentially requiring rework. Replacing a faulty vibration pump with a genuine OEM unit restores the machine to its rated compaction performance.
