Reduced hydraulic efficiency in EX120 and ZX120 excavators often leads to slower working cycles and unstable digging performance during extended jobsite operation. The 9192497 / 9197338 / 9227923 pump assembly is built around HPK055 variable displacement technology, enabling stable hydraulic output recovery and consistent system pressure across varying load conditions.
