Bombas de pistões axiais

Type AKP 500 bar 0,1 up to 0,30 cm3/rev

Features

  • High volumetric efficiency (also by very low speed rates)
  • Low noise level
  • Various speed ranges
  • Continuous self lubrication and cooling through the suction flow
  • Small mounting dimensions
  • Automatic venting by raising and lowering the pressure or by switching the motor on and off several times
  • Venting time can be shortened essentially through a pre-filling

Design

  • Design with 3 or 5 pumping elements
  • Valve controlled on pressure and suction side (not usable as motor)
