The Bomag 05813062 Charge Pump is a genuine OEM component designed for Bomag BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this charge pump matches the exact specifications of the original unit installed at the factory. It delivers the correct flow rate and pressure needed to keep the hydraulic drive system primed and functioning as intended across all five compatible machines.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original flow and pressure specifications, ensuring the hydraulic circuit receives consistent charge pressure without cavitation or pressure drop
- Direct OEM Replacement — this charge pump is engineered to install directly in place of the original unit on BW-series trench compactors, with matching port sizing and mounting geometry
- Broad Trench Compactor Coverage — fits the BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors, covering multiple size classes within the BW T-series lineup
- Sustained Drive System Performance — a properly functioning charge pump maintains the hydraulic pressure needed for responsive propulsion and vibration output; a worn or failed pump leads to sluggish travel, loss of compaction force, and potential damage to the main hydraulic pump
- Verified Part Number Fit — ordering by Bomag part number 05813062 confirms you are receiving the correct pump for your machine, eliminating the risk of fitment mismatches on critical hydraulic components
The charge pump is a key element of the hydraulic system in a trench compactor, responsible for maintaining positive pressure in the closed-loop hydrostatic drive circuit. It supplies a continuous flow of low-pressure fluid to prevent cavitation and keep the main hydraulic pump and motor operating efficiently. When the charge pump wears out or fails, the machine may exhibit loss of drive power, overheating of hydraulic fluid, or erratic compaction behavior — making prompt replacement essential to restoring full machine performance.
