XCMG Road Roller Gear Pump 803086849 CBFB-F25ALY-L | Hydraulic Pump XS183/XS263J

产品特点与应用

This Hydraulic Gear Pump (PN 803086849 / Model CBFB-F25ALY-L)​ is a high-pressure aluminum-body pump engineered for XCMG XS183 / XS263J vibratory road rollers, typically serving as a work-circuit or steering-circuit feed pump. Decoded from the model: F25 = 25 ml/r displacement, A = opposed-key shaft, L = left-hand rotation (viewed from shaft end), Y = threaded port connections—rated 20 MPa (max 25 MPa) at 2000–2500 r/min. The pump housing is high-strength aluminum alloy with hardened alloy steel gears; internal floating side plates with DU bearings provide automatic clearance compensation, maintaining high volumetric efficiency (>91%) even as the unit wears in. Direct flange-and-key mounting matches the OEM pump pad—same bolt pattern, same shaft centerline, same port thread—so installation requires no bracket mods or coupler changes. Each unit is bench-run for flow, pressure hold, and rotation verification before shipment.
