The Bomag 05800983 Vibration Pump is a genuine OEM component designed for BW 161 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers. Sourced directly from Bomag, this vibration pump meets the same specifications as the original unit installed at the factory, ensuring correct hydraulic output and seamless integration with the drum vibration circuit. If your tandem roller is producing weak or inconsistent compaction, a worn or failing vibration pump is a common cause — replacing it with the correct OEM part restores full vibratory performance and protects downstream hydraulic components.
Key Features
- OEM Hydraulic Precision — Manufactured to Bomag's exact flow and pressure specifications for the vibration circuit, so the drum delivers consistent centrifugal force on every pass.
- Direct-Fit Replacement — Engineered to match the original pump's port configuration and mounting interface, allowing a straightforward swap with no circuit modifications.
- Confirmed Tandem Roller Fitment — Verified for BW 161 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers, giving you confidence you're ordering the right part for your machine.
- Sustained Compaction Output — A properly functioning vibration pump maintains the hydraulic pressure needed to drive drum amplitude and frequency at rated performance, delivering uniform mat density pass after pass.
- Protects the Broader Hydraulic System — An OEM pump with correct clearances and sealing reduces the risk of internal leakage that can overheat fluid and damage motors, valves, and other hydraulic components.
The vibration pump is the hydraulic heart of the drum exciter system on a tandem roller. It converts mechanical power from the engine into pressurized hydraulic flow, which drives the eccentric shaft inside the drum to generate the vibratory force that compacts asphalt. When the vibration pump wears or fails, hydraulic flow drops, drum vibration becomes erratic or stops entirely, and compaction quality deteriorates — often leading to surface defects and rework. Replacing a failing pump promptly with a correctly specified unit like this one keeps the vibratory system operating at its intended amplitude and frequency.
