description

Part number: 804001796
Part name: gear pump
Unit name: hydraulic system
Applicable Models: XCMG XS265 vibratory road roller

Gear pump is the power source component of road roller hydraulic system. It generates pressurized oil through gear meshing, and delivers pressure oil for travel, vibration and steering hydraulic circuits to guarantee normal output of compaction and traveling functions. Worn gear, scratched housing and aged seals will cause insufficient pressure, reduced flow rate, oil leakage and abnormal noise, directly result in weak vibration and poor travel performance, and reduce compaction efficiency.

=======================================

advantages

Port specification, displacement and mounting dimension are consistent with original parameters, good interchangeability for direct installation without pipeline or support modification.
High‑precision gear with reasonable fitting clearance ensures high volumetric efficiency, stable flow output and good hydraulic‑impact resistance.
Oil‑resistant and high‑temperature‑resistant sealing components adapt heavy‑load alternating working condition of road roller and reduce leakage failure.
Integrated assembly design reduces on‑site parts assembly work, easy for disassembly and maintenance, convenient for overseas project spare‑parts stocking.

FAQ

Q: Can gear pump with slight oil leakage keep working?
A: Leakage will worsen gradually accompanied by pressure decay, long‑time operation accelerates internal wear, timely replacement is recommended.
Q: Why pressure still cannot reach target after gear pump replacement?
A: Check suction pipe air leakage, inspect suction filter clogging and verify coupling slipping or wear.
