    Parker F12 Motor/Pump Series

    Share this post

    With our extensive, competitive access to both leading and lesser-known, niche hydraulic equipment manufacturers from around the world, many of our customers choose to rationalise their supplier base and work with us as their single source of supply… and the recipient of these Parker F12 series bent axis fixed displacement motors is no exception!

    Our philosophy is one of not just “taking orders”, unless that’s all that our customers want and need us to do. Instead, we make it our business to understand your business, and work so closely with many of our customers that they consider us to be part of their own team…  meaning that they can then focus on managing their products, their customers, their markets.

    Parker F11 F12Parker F11 and F12 series are bent axis, fixed displacement heavy duty motor/pump series. They can be used in numerous applications in both open and closed loop circuits.

    Series F11 is available in 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 and 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 while 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 self-priming 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 and their 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.

    A simple and straightforward design with very few moving parts, makes the F11 and F12s 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.
