The Bomag 05546722 Pump Unit is a genuine OEM component designed for BW 170 and BW 174 series tandem rollers. Sourced directly from Bomag, this pump unit delivers the exact fit and hydraulic performance required to keep these machines operating at full specification. It is compatible across a wide range of BW 174 variants, including the BW 174 AC, BW 174 AD, BW 174 AP, BW 174 ACP, BW 174 AC-2, BW 174 AD-2, and their AM-suffix counterparts, as well as the BW 170 AD, BW 170 AD-2 AM, and BW 170 AP AM tandem rollers. When hydraulic pump performance degrades, replacing it with a genuine Bomag part ensures the system returns to correct operating pressure and flow.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original hydraulic pressure and flow specifications, ensuring the pump unit performs exactly as the system was engineered to deliver
- Drop-In Replacement — engineered to match the original mounting interface and porting configuration, allowing direct installation on compatible BW 170 and BW 174 tandem rollers without modification
- Broad BW 170 and BW 174 Coverage — fits the BW 170 AD, BW 170 AD-2 AM, BW 170 AP AM, BW 174 AC, BW 174 AD, BW 174 AP, BW 174 ACP, BW 174 AC-2, BW 174 AD-2, and all AM-suffix variants of these models
- Sustained Compaction Output — a correctly functioning pump unit maintains consistent hydraulic pressure to drive the drums and propulsion system, directly supporting compaction quality and pass efficiency on asphalt surfaces
- Verified Bomag Part Number — ordering by part number 05546722 confirms you are receiving the correct unit for your machine, eliminating compatibility guesswork on the job
The pump unit is the heart of the hydraulic system on Bomag tandem rollers, generating the pressurized fluid flow that powers drum drive, propulsion, and steering functions. When this component wears or fails, the machine may lose drive force, exhibit sluggish response, or become unable to maintain consistent drum rotation — all of which directly compromise compaction quality and paving productivity. Replacing a worn pump unit with a genuine Bomag part restores full hydraulic output and returns the roller to its designed operating condition.
