6x8 ELEMENT PUMP COUPLING

(HIGH TORQUE TRANSMISSION – FLEXIBLE CONNECTION – VIBRATION DAMPING STRUCTURE)

The 6x8 element pump coupling is designed to provide a flexible and secure connection between the hydraulic pump and the PTO or engine output. Thanks to the elastomer elements of the coupling, it dampens vibrations and ensures quieter and longer-lasting system operation. The 6x8 configuration consists of 6 inner connection teeth and 8 outer connection elements; this structure provides high torque transmission and axial misalignment tolerance. It is generally used in tipper trucks, vacuum trucks, sweeper vehicles, and stationary hydraulic systems.
