Working Principle
As a premium Hydraulic piston pump, this hydraulic pump transforms rotational mechanical energy into hydraulic pressure energy for the complete hydraulic system. Driven by input shaft, the cylinder block drives pistons for reciprocating movement. By changing the swash‑plate tilt angle, output displacement and flow can be adjusted. The built‑in pressure compensator detects system pressure in real‑time; when system pressure reaches preset value, swash‑plate angle reduces automatically to cut flow output, achieving energy‑saving standby for the Machine.
Wear on pistons, valve plate or bearing components will trigger internal leakage, pressure drop and insufficient flow of the hydraulic pump. Overhaul or genuine spare‑parts replacement can restore full‑range performance of your hydraulic system.
