Applications:

  • Single and multi-station pumps
  • Mobile or stationary auxiliary drives
  • Connect / disconnect direct drives
  • Winches, reels, hoists and more

Advantages:

  • Simple, efficient, high-torque design
  • Reduces fuel consumption and CO2 emissions: engaging drives and pumps (only when required)
  • Easier-engine starts: lowers horsepower draw and cranking power required during machine start-up by disconnecting the hydraulic system from the engine
  • Reduces ambient noise: through intermittent use of pumps and equipment
  • Cooler running hydraulic systems: heat is generated whenever oil dumps from high to low pressure without producing work. Disconnecting the PTO Clutch reduces the destructive effects of heat – lowering maintenance costs and hydraulic oil requirements
  • Extends the life of drive systems and components
