Reliability
  • Available in 2, 4, or 6 pole motor speed, these units sit next to the tank of your hydraulic machinery and pump the heat away to the air. There is no need to disturb the main-circuit hose seals on your machine.
  • The G-rotor pump is a reliable unit, delivering approximately 30 litre per minute oil flow to the heat exchanger.
