The KPTO is a fluid coupling enclosed into a box connected to the Diesel engine by SAE housing. The KPTO has been designed to meet the market requirements for a unit combining the technical features of a conventional Power Take Off with the performances of a fluid coupling. The KPTO has an integral feeding pump driven by the Diesel engine.
A remote electrically operated ON-OFF valve allows the fluid coupling circuit feed when turned ON and a rapid oil drain through orifices located on the periphery of the fluid coupling when turned OFF.
The forced bearing lubrication is continuously assured.
The KPTO range is suitable for powers up to 1000 kW.
The engine flywheel is connected to the KPTO input by an elastic coupling. The output shaft can be connected to the driven machine by elastic coupling cardan shaft or pulley.
Standard accessories include: oil feeding pump oil filter with pressure and temperature gauges ON-OFF electric valve oil temperature switch and oil level indicators.
Optionals accessories include: water or air heat exchanger quick release valves output pulleys elastic couplings output flange for cardan shafts and cardan shafts too.


The KPTO drain type fluid coupling allows a disconnect or the engine from the load granting the following advantages:

  • unloaded engine warm up
  • smooth start up no belt slip
  • shock and overload protection
  • absorbtion of vibration
  • high radial load capacity
  • remote control by electric valve
  • load positioning
  • cheap and easy maintenance due to external mounting of the main accessories like oil filter feeding pump and control valve
  • longer life thanks to no friction linings to wear out
