Optimal Engine Power through Hydro-Mechanical Torque Control Eaton has added Hydro-mechanical Torque Control option for the versatile 420 series pump product line. Torque control limits the amount of input power that an open circuit pump will draw from the engine or prime mover. This control prevents engine stalling and helps in optimal utilization of engine power. This control allows a wide variety of application options to be met by a single pump control option.
Hydro-mechanical torque control provides a simple, low cost option for open circuit pumps. This new control complements the power-dense package offered by the 420 series product and is available in all four displacements (41cc, 49cc, 62cc & 80cc).
