The Bomag 05802575 Tandem Pump is a genuine OEM component designed for Bomag BW 177 and BW 179 single drum rollers and BW 154 and BW 174 tandem rollers. As a factory-sourced part, this tandem pump meets the original engineering specifications Bomag set for these machines, ensuring correct hydraulic output and system compatibility right out of the box. This pump serves a wide range of -4 and -4i generation models, including the BW 177 DH-4, BW 177 PDH-4, BW 179 DH-4, BW 179 PDH-4, BW 154 AP-4, BW 154 ACP-4, BW 174 AP-4, BW 174 AP-4i, BW 174 APO-4i, and BW 174 ACP 4I AM, among others. When your hydraulic system needs a pump replacement, this genuine OEM part restores full system pressure and flow without the guesswork of non-OEM alternatives.
Key Features
- Genuine OEM Hydraulic Integrity — sourced directly from Bomag, this tandem pump is manufactured to exact original flow-rate and pressure specifications, ensuring the hydraulic circuits it serves perform as designed
- Direct-Swap Replacement — engineered to the same port configuration and mounting dimensions as the original unit, this pump installs into the existing hydraulic circuit without modification to lines or fittings
- Broad Model Coverage — fits Bomag BW 177 and BW 179 single drum rollers and BW 154 and BW 174 tandem rollers across multiple -4 and -4i generation variants, including AM, PB, ACP, and APO configurations
- Sustained Drive and Vibration Performance — a tandem pump simultaneously supplies hydraulic power to both the travel drive and vibratory circuits; a worn or failed pump causes loss of propulsion, vibration, or both, halting compaction work entirely
- Verified Part Number Traceability — ordering by Bomag part number 05802575 confirms you receive the correct pump for your specific roller variant, eliminating the risk of an incorrect unit arriving on site
A tandem pump is a dual-section hydraulic pump that delivers pressurized fluid to two independent hydraulic circuits from a single driven unit. On Bomag single drum and tandem rollers, this typically means one pump section powers the hydrostatic travel drive while the second feeds the vibratory drum circuit, allowing both functions to operate simultaneously and independently. When the tandem pump wears internally or fails, hydraulic pressure drops in one or both circuits, resulting in sluggish or absent drum travel, loss of vibration amplitude, or complete machine shutdown — making prompt replacement critical to keeping compaction output on schedule.
