The Bomag 05821500 Compensation Tank is a genuine OEM component designed for a wide range of Bomag BW-series tandem rollers, single drum rollers, and pneumatic tyred rollers. Sourced directly from Bomag, this part meets original equipment specifications, ensuring a direct, no-hassle installation on compatible machines. This compensation tank is confirmed to fit models including the BW 141 AD-5, BW 151 AD-5, BW 161 AD-5, BW 177 D-5, BW 191 AD-5, BW 202 AD-5, BW 206 AD-5, BW 145 D-5, BW 177 DH-5, BW 11 RH-5, and BW 28 RH, among many others across the -5 and -50 generation lines. Choosing an authentic Bomag replacement keeps your hydraulic or cooling system operating at the pressures and volumes the machine was designed to handle.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications, ensuring the tank walls, fittings, and mounting points match what came off the machine
- Direct-Fit Replacement — engineered to install in the original mounting position with original-spec connections, eliminating the need for adapters or rework
- Broad BW-Series Coverage — fits tandem rollers including the BW 141 AD-5, BW 151 AD-5, BW 161 AD-5, BW 190 AD-5, BW 191 AD-5, BW 202 AD-5, and BW 206 AD-5, single drum rollers including the BW 145 D-5, BW 145 DH-5, BW 177 D-5, BW 177 DH-5, and BW 177BVC-5, and pneumatic tyred rollers including the BW 11 RH-5 and BW 28 RH
- System Pressure Integrity — a properly functioning compensation tank maintains correct fluid volume and pressure balance in the hydraulic circuit; a cracked or failed tank leads to pressure loss, erratic drum drive behavior, and potential pump damage
- Verified Part Number — order with confidence using Bomag part number 05821500, cross-referenced against the original BOMAG catalog for the models listed
The compensation tank serves as a reservoir and pressure buffer within the machine's hydraulic system, absorbing volume changes caused by thermal expansion of fluid and fluctuations in circuit demand. By maintaining a consistent fluid level and cushioning pressure spikes, it protects downstream components such as pumps, motors, and control valves from stress and cavitation. When the compensation tank cracks, leaks, or loses its sealing capacity, hydraulic pressure becomes unstable, which can manifest as sluggish or uneven drum drive, overheating fluid, and accelerated wear across the entire hydraulic circuit.
