Get to Know Poclain Medium Duty Closed Loop Pumps

First things first… what is a closed loop axial piston pump?

The basics:

A closed loop axial piston pump enables mobility with a hydrostatic transmission generally comprised of

  • an endothermic engine
  • a closed loop variable displacement pump
  • a hydraulic wheel motor

This type of configuration makes the most sense for mobile machines if you need to achieve:

  • Variations in speed
  • Brake function
  • Traction

The pump’s reversibility is what makes this possible in a closed loop circuit. An open loop circuit would require both a hydraulic distributor to reverse the direction of the flow and an additional hydraulic component to address braking.

With two hydraulic pump loop options, open circuit or closed circuit, a closed circuit loop saves valuable system space by offering continuous fluid flow without the need for additional parts. In comparison, an open circuit loop typically requires a larger reservoir and as a result, increases the system’s footprint.
