They can be usedin numerous applications in both open and closedloop circuits.

Series F11 is available in the following framesizes and versions:- F11-5, -10, 19 and -150 with CETOP mounting flange and shaft end- F11-19, -150 and -250 with SAE flange and shaft Series F12 conforms to current ISO and SAEmounting flange and shaft end configurations.A very compact cartridge version is alsoavailable.Frame sizes: F12-30, -40, -60, -80 and -110.

Thanks to the unique spherical piston design,F11F12 motors can be used at unusually highshaft speeds.

Operating pressures to 7000 psiprovides for the high output power capability.

The 40 angle between shaft and cylinder barrelallows for a very compact, lightweight motorpump.

The laminated piston ring offers importantadvantages such as low internal leakage andthermal shock resistance.

The F11F12 motors produce very high torqueat start-up as well as at low speeds.

Our unique timing gear design synchronizesshaft and cylinder barrel, making the F11F12very tolerant to high G forces and torsionalvibrations.

Heavy duty roller bearings permit substantialexternal axial and radial shaft loads.

The F11s and F12s have a simple and straight-forward design with very few moving parts,making them very reliable motorspumps.

The unique piston locking, timing gear andbearing set-up as well as the limited number ofparts add up to a very robust design with longservice life and, above all, proven reliability.
