Vane motors

With displacements ranging from 44 cm3 to 317 cm3 [2.7 in3 to 19.3 in3], our vane motors provide an efficient and economical means of applying rotary hydraulic power with variable speed. They can operate on a wide range of fluids, including water-glycol, and they are hydraulically balanced to ensure efficiency and low vibration throughout their service lives.

Features and benefits  

  • Reliable -- Danfoss has field-proven these high-performance motors over many years 
  • Dual-alternate pressure plate design provides overall efficiency of about 86 percent. 
  • May be reversed simply by reversing the direction of oil flow  
  • Suited to series applications
  • Inlet and outlet ports can be pressurized simultaneously without affecting service life or operating smoothness
  • A cartridge can be replaced without removing the unit from the application, and usually without disconnecting hydraulic lines  
  • High speed and pressure 

Applications 

  • Excavators
  • Loaders
  • Seeders
  • Harvesters
  • Forklifts
  • Cranes

Specifications 

  • Displacement:  44 cm3 to 317 cm3 [2.7 in3 to 19.3 in3]
  • Continuous pressure ratings: up to 172 bar [2,500 psi]
  • Speeds: up to 3,000 rpm at maximum pressure; speeds up to 4,000 rpm are obtainable, as in transmission applications where high travel speeds under light loads are required.
