H1 piston pumps are available in 60cm3/68cm3 and 89cm3/100cm3 frame sizes. Electronic control options help compensate for reduced power of Tier IV/Stage IV engines. Electric-only control options include EDC: electrical displacement control (with mechanical feedback), for load-independent speed control; FNR: forward/neutral/reverse, for simple on/off work function control; and NFPE: non-feedback proportional electrical control, for load dependant control systems. High-response pressure limiter manages load on engine and limits pressure by reducing oil volume that flows over pressure relief valve.
