Linde assures high-quality performance everyday regardless of terrain, environment or application. The Linde Closed Loop system includes a series of compact, variable displacement pumps with an optional, High Pressure Override and interchangeable controls. Whether you need a Manual, Hydraulic-Remote or Electro-Hydraulic control, these components provide precision control that is critical during proportional drive. For rugged applications, these pumps include a same side PTO with easier installation of tandem pumps.
