Parker Hydraulic Motors and Pumps ​

   F11/F12 series

F11 and F12 are bent axis, fixed displacement heavyduty motor/pump series. They can be used in numerous applications in both open and closed loop circuits.
Series F11 is available in the following frame sizes and versions:
  •   F11-5, -10, -14, 19 and -150 with CETOP mounting flange and shaft end. 

  •    F11-14 with ISO flange and shaft . 

  •    F11-14, -19, -150 and -250 with SAE flange and shaft. 

  • Series F12 conforms to current ISO and SAE mounting flange and shaft end configurations. A very compact cartridge version is also available. 

  • Thanks to the unique spherical piston design, F11/F12 motors can be used at unusually high shaft speeds. Operating pressures to 480 bar provides for the high output power capability. 

  • The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor/pump. 

  • The laminated piston ring offers important advantages such as low internal leakage and thermal shock resistance. 

  • The pump version has highly engineered valve plates for increased selfpriming speed and low noise, available with left and right hand rotation. 

  • The F11/F12 motors produce very high torque at start-up as well as at low speeds. 

  • Our unique timing gear design synchronizes shaft and cylinder barrel, making the F11/F12 very tolerant to high 'G' forces and torsional vibrations. 

  • Heavy duty roller bearings permit substantial external axial and radial shaft loads. 

  • The F11's and F12's have a simple and straightforward design with very few moving parts, making them very reliable motors/pumps. 

  • 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.​

PV Plus Series:

General Information:
Fluid recommendations Premium quality hydraulic mineral fluid is recommended, like HLP oils to DIN 51524, part 2. Brugger- value has to be 30 N/mm2 minimum for general application and 50 N/mm2 for heavily loaded hydraulic equipment and fast cycling machines and/or high dynamic loads, measured in accordance with DIN 51 347-2. See also Document HY30-3248/UK Parker Hydraulic Fluids.

The normal operating viscosity should range between 16 and 100 mm2/s (cSt). Max. start-up viscosity is 800 mm2/s (cSt).

For maximum pump and system component functionality and life, the system should be protected from contamination by effective filtration. Fluid cleanliness should be in accordance with ISO classification ISO 4406:1999. The quality of filter elements should be in accordance with ISO standards. General hydraulic systems for satisfactory operation: Class 20/18/15, according to ISO 4406:1999.

Seals Check hydraulic fluid specification for chemical resistance of seal material. Check temperature range of seal material and compare with max. system and ambient temperature.
