420 Series Piston Pumps

A hydro-mechanical torque control option and several performance upgrades have been added to the 420 open-circuit piston pump line.

  • Hydro-mechanical torque control automatically senses heavy loads and adjusts hydraulic fluid flow accordingly
  • Pump housing designed to decrease airborne noise to 76 dBA at 1,800 rpm
  • Case-to-inlet check valve improves cold weather operation and provides added protection to the seals and rotating group
