The Bomag 05801379 Variable Displacement Pump is a genuine OEM component designed for the BW 850 T trench compactor. Sourced directly from Bomag, this pump meets the exact engineering specifications required for proper hydraulic system operation on the BW 850 T. As a genuine OEM part, it installs as a direct replacement with no guesswork on fitment or compatibility. Buyers can order with confidence knowing part number 05801379 is the correct, factory-authorized pump for this machine.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to Bomag's exact displacement and pressure tolerances, ensuring the pump delivers consistent hydraulic flow and output specific to the BW 850 T's drive and compaction system.
- Direct OEM Replacement — This variable displacement pump mounts and connects to existing hydraulic lines and fittings on the BW 850 T without adaptation, matching the original pump's port configuration and shaft interface.
- Confirmed Fitment for the BW 850 T — Verified by Bomag's own parts catalog as the correct pump for BW 850 T trench compactors, eliminating compatibility uncertainty at the point of purchase.
- Sustained Hydraulic Performance — A properly functioning variable displacement pump continuously adjusts flow to match load demand, keeping compaction force and travel drive responsive under varying ground conditions.
- Protects Downstream Hydraulic Components — An OEM-matched pump maintains correct system pressure, reducing stress on motors, valves, and hoses that can result from over- or under-pressurized hydraulic circuits.
A variable displacement pump is the heart of the hydraulic system on a trench compactor like the BW 850 T. It converts mechanical engine power into pressurized hydraulic flow, automatically varying its output volume in response to the load placed on the system — whether powering the drive circuit, the vibration system, or both simultaneously. When this pump wears or fails, the machine loses hydraulic pressure and flow, resulting in sluggish travel, reduced compaction force, or a complete loss of machine function until the pump is replaced.
