The Bomag 88012031 Compensation Tank is a genuine OEM component designed for a wide range of Bomag tandem rollers, trench compactors, and cold milling machines. Sourced directly from Bomag, this compensation tank meets the original engineering specifications for every machine it serves, including BW 80 AD-5, BW 100 AD-5, BW 120 AD-5, BW 125 AD-4, BW 131 AD-5, BMP 8500, and BM2000/65 Stage V models, among others. As a genuine OEM part, part number 88012031 delivers the exact dimensions, material grade, and connection interfaces required for a correct installation with no guesswork. Buyers who demand original-quality hydraulic system components will find this compensation tank is the right choice for restoring proper fluid management on their Bomag equipment.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional standards, ensuring the tank's wall integrity and connection ports match what the hydraulic system was engineered around
- Direct-Fit Replacement — mounting points, fittings, and capacity match the original installation, allowing this tank to drop into place without modification on compatible machines
- Broad Tandem Roller Coverage — confirmed fitment across Bomag's BW 80, BW 90, BW 100, BW 115, BW 120, BW 125, and BW 131 tandem roller series, including AC, AD, SC, SL, SLM, SLC, SCC, ACM, ADM, and ACW variants in -4 and -5 generations
- Extended Compatibility — also fits the BMP 8500 and BMP 8500 Kohler trench compactors and BM2000/65 Stage V and BM2200/65 Stage V cold milling machines, making part number 88012031 a versatile stock item for multi-machine fleets
- Hydraulic System Stability — a functioning compensation tank maintains correct fluid volume and pressure balance in the hydraulic circuit; a cracked or failed tank leads to fluid loss, erratic system pressure, and potential damage to pumps and motors
A compensation tank serves as the hydraulic system's fluid reservoir buffer, absorbing volume changes caused by thermal expansion and contraction of hydraulic fluid as the machine heats up and cools down during operation. By maintaining a stable fluid supply to the hydraulic circuit, it prevents cavitation, pressure spikes, and air ingestion that can accelerate wear on pumps, motors, and control valves. When a compensation tank develops a crack, leak, or a failed port fitting, the hydraulic system loses its ability to self-regulate fluid volume, which can quickly progress from minor seepage to a full hydraulic failure if left unaddressed.
