Service ManualSeries F12HY30-5504-M1/UKGeneral informationF12 is bent axis, fixed displacement heavyduty motor/pump seris. They can be usedin numerous applications in both open andclosed loop circuits.The pump version has highly engineeredvalve plates for increased selfpriming speedand low noise, available with left and righthand rotation.Series F12 conforms to current ISO andSAE mounting flange and shaft end configurations. A very compact cartridge version isalso available.Frame sizes: F12-30, -40, -60, -80, -90,-110, -125, -150, -250.The F12 motors produce very high torqueat start-up as well as at low speeds.Thanks to the unique spherical piston design, F12 motors can be used at unusuallyhigh shaft speeds. Operating pressures to480 bar provides for the high output powercapability.The 40 angle between shaft and cylinderbarrel allows for a very compact, lightweightmotor/pump.The laminated piston ring offers importantadvantages such as low internal leakageand thermal shock resistance.F12 cross section98765432112Our unique timing gear design synchronizesshaft and cylinder barrel, making the F12very tolerant to high ’G’ forces and torsionalvibrations.Heavy duty roller bearings permit substantial external axial and radial shaft loads.The 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 andbearing set-up as well as the limited number of parts add up to a very robust designwith long service life and, above all, provenreliability.34567891.
