Bomag 08821412 Dosing Device

The Bomag 08821412 Dosing Device is a genuine OEM component designed for a broad range of Bomag rollers, cold milling machines, and pavers. This dosing device is factory-sourced to deliver the exact fit and function required across BW-series tandem rollers — including the BW 161 AD-5, BW 190 AD-5, BW 191 AD-5, BW 202 AD-5, and BW 206 AD-5 — BW-series single drum rollers such as the BW 211 D-5, BW 213 D-5, BW 216 D-5, BW 219 D-5, and BW 226-5, and the BW 28 RH pneumatic tyred roller. Coverage also extends to BM 500/15 Stage V, BM 600/15 Stage V, BM 500/15-2, and BM 600/15-2 cold milling machines, as well as BF 600 P-3 S 500, BF 700 C-3 S 500, BF 700 C-3 S 600, and BF 800 C-3 S 600 pavers. As a genuine Bomag part, this component meets the same specifications as the unit installed at the factory, ensuring proper dosing system operation across all listed machines.

Key Features

• Genuine OEM Metering Precision — sourced directly from Bomag, this dosing device meets the exact flow and metering tolerances required for correct system function, unlike generic alternatives that may deliver inconsistent output
• Direct-Fit Replacement — engineered to the same specifications as the original unit, this part installs using existing mounting points and connections with no alteration to surrounding components
• Broad Equipment Coverage — fits BW-series tandem rollers, single drum rollers, the BW 28 RH pneumatic tyred roller, BM-series cold milling machines, and BF-series pavers, making part number 08821412 a versatile stock item for mixed Bomag fleets
• Consistent Dosing Output — a correctly functioning dosing device ensures the fluid or additive it meters is delivered at the right rate; a worn or faulty unit leads to under- or over-dosing that can affect compaction quality, surface treatment, or machine operation
• Verified Part Number Integrity — ordering by Bomag part number 08821412 eliminates fitment guesswork and ensures the correct component arrives the first time

A dosing device controls the measured delivery of a fluid — typically water, emulsion, or another process medium — to a specific point in the machine's system. It regulates flow rate to ensure the correct volume reaches its target, whether that is drum wetting on a roller, cutting drum cooling on a milling machine, or material treatment on a paver. When this component wears or fails, dosing becomes erratic or stops entirely, which can lead to material sticking to drums, overheating of cutting components, or uneven application of treatment agents — all of which compromise output quality and can accelerate wear on related components.
