The Multiquip 50322 Driving Pump RW-3015 P54 KA KA4B is a genuine OEM hydraulic drive pump designed for KA4B and RW-3015 RAMMAX ride-on roller models. As a direct OEM replacement, this pump is manufactured to the same specifications as the original unit, ensuring a proper fit and correct hydraulic output for your roller's propulsion system. This part is confirmed for KA4B and RW-3015 applications and is sourced directly through Multiquip's authorized parts network. Order with confidence knowing you are receiving an authentic Multiquip component backed by OEM quality standards.
Key Features
- Genuine OEM Hydraulic Specification — Manufactured to the original pump displacement and pressure ratings required by the RAMMAX roller drive circuit, so hydraulic output stays consistent and the machine performs as designed.
- Direct-Mount Replacement — Matches the original mounting flange, port configuration, and shaft dimensions of the production unit for a straightforward swap without custom adapters.
- Confirmed Fitment for KA4B and RW-3015 — Validated for RAMMAX KA4B and RW-3015 ride-on roller models, eliminating compatibility guesswork before you pull the machine out of service.
- Sustains Full Drive Performance — A correctly functioning drive pump delivers consistent hydraulic pressure to the propulsion circuit; a worn or failing pump causes loss of tractive effort, erratic forward/reverse response, and uneven compaction passes.
- Hydraulic Circuit Integrity — Built to OEM sealing and internal clearance tolerances, helping prevent internal bypass and system pressure loss that can cascade into broader hydraulic circuit damage.
The driving pump is the heart of the hydraulic propulsion system on a RAMMAX ride-on roller. It converts mechanical engine power into pressurized hydraulic flow, which is routed to the drive motors to move the machine forward and in reverse across the compaction surface. When the driving pump wears or fails, the roller loses the hydraulic pressure needed to propel itself, resulting in sluggish travel, loss of directional control, or a complete inability to move — all of which halt compaction work immediately. Replacing a worn pump with a correct OEM unit restores full system pressure and responsive machine control.
