The Bomag 05813172 Gear Pump is a genuine OEM component designed for the BMP 851 trench compactor. Sourced directly from Bomag, this gear pump meets the same build standards as the original unit installed at the factory, ensuring correct hydraulic output for the machine's compaction system. This is a direct-fit replacement for the BMP 851, making it the straightforward choice when restoring hydraulic performance on this machine.
Key Features
- Genuine OEM Hydraulic Output — manufactured to Bomag's exact flow and pressure specifications, so the pump delivers the hydraulic force the BMP 851's compaction drive system demands
- Exact-Fit Replacement — engineered to the same port configuration and mounting dimensions as the original, allowing straightforward installation without reworking hydraulic lines or mounting hardware
- Confirmed Fitment — part number 05813172 is verified for the BMP 851 trench compactor, taking the guesswork out of parts sourcing for this machine
- Restored Compaction Force — a correctly functioning gear pump maintains consistent hydraulic pressure across the compaction cycle; a worn pump causes pressure drop, reduced drum force, and uneven soil compaction
- Hydraulic System Integrity — using the correct OEM pump prevents pressure imbalances that can accelerate wear on downstream hydraulic components such as motors, valves, and seals
A gear pump is the hydraulic heart of the BMP 851 trench compactor, converting mechanical engine power into pressurized hydraulic flow that drives the drum, travel system, and steering functions. It works by meshing rotating gears to draw fluid in on the inlet side and force it out under pressure on the outlet side, maintaining a steady flow rate that the machine's hydraulic circuits depend on. When a gear pump wears or fails, internal leakage reduces pressure and flow, resulting in sluggish or unresponsive machine movement, loss of compaction effectiveness, and potential overheating of the hydraulic system.
