F11 Series Motor/Pump

Axial Piston Fixed Displacement, Bent-Axis Hydraulic Motors – Small Frame, Displacement 5-19cc, Intermittent Pressure Up To 420 bar (6090 psi), Continuous Operating Pressure Up To 350 bar (5075 psi), Speeds Up To 14000 RPM.

F11 is a bent-axis, fixed displacement motor/pump. It can be used in numerous applications in both open and closed loop circuits.

F11 Features:

  • Max intermittent pressure up to 420 bar (6090 psi) and continuous operating pressure up to 350 bar (5075 psi)
  • Thanks to low weight pistons and a compact design of the rotating parts, the F11 tolerates very high speeds, up to 14000 rpm
  • CETOP, ISO, SAW and SAE versions

General F Series Features:

  • The laminated piston ring offers important advantages such as unbeatable efficiency and thermal shock resistance
  • High allowable speeds and operating pressures means high output power
  • The unique piston locking, timing gear and bearing set-up as well as the limited number of parts add up to a very robust design with long service life and, above all, proven reliability.
  • The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor/pump.
  • Small envelop size and a high power-to-weight ratio
  • The motor version has highly engineered valve plates for high speed and low noise
  • The pump version has highly engineered valve plates for increased self priming speed and low noise, available with left and right hand rotation.
  • Our unique timing gear design synchronizes shaft and cylinder barrel, making the F10/F11/F12 very tolerant to high ‘G’ forces and torsional vibrations.
  • Heavy duty roller bearings permit substantial external axial and radial shaft loads

    Power Boost A high speed F11 or F12 motor could be optimized with a Power Boost™, which means less fluid friction and oil compression. This can reduce power losses by up to 5 kW. The improved efficiency generates less heat, reducing the need for cooling and consequently improves fuel consumption. -
