・1:1 OEM interchange, perfect matching for Volvo articulated dumper hydraulic system
11190766 piston pump is manufactured strictly according to original drawing standards. All mounting dimensions, oil port layout and spline shaft parameters are fully consistent with VOE11190766 original pump. It can be directly installed on Volvo A25/A30/A35/A40D/E without redesigning pipelines or brackets.
・Alloy steel plunger & cylinder block with nitriding treatment, outstanding wear resistance
Core friction pairs adopt nitriding hardening process, greatly improving surface hardness and anti-abrasion performance. It maintains high volumetric efficiency under long continuous mining operation, reducing internal leakage and extending service life.
・Integrated variable regulator, intelligent power matching and energy saving
Built-in pressure-flow compound regulator automatically adjusts pump displacement according to load demand. It avoids power waste during light-load operation and protects hydraulic system from overload under heavy load, lowering fuel consumption.
・Heavy-duty cast iron housing, strong impact resistance for mining harsh environment
The pump housing adopts high-density cast iron plus stress-relief annealing, resisting frequent vibration and pressure impact in quarry and mine sites. It prevents shell cracking and deformation under long-time heavy transport cycles.
