Open Circuit Constant Pumps

Constant Pump - Geared Motor Series F11 / F12

F11 and F12 are robust bent axis motors / pumps with fixed displacement . They can be used in numerous applications for open and closed hydraulic circuits.

• The F11 series is available in the following nominal sizes and designs:
  - F11-5, -10, -12, -14, -19 und -150 (CETOP-Flange and -Wellenende)
  - F11-10, -12 and-14 with ISO-Flange and -Wellenende
  - F11-10, -12, -14, -19, -150 and -250 (SAE-Flange und -Welle).
• The F12 series is available as standard in ISO and SAE standards. In addition, a very short slide-in version is also available 
  Ratings: F12-30, -40, -60, -80, -90, -110 and -125.
• Thanks to the use of spherical flask, the F11 / F12 motors can drive as unusually high speeds. At operating pressures up to 480 bar very high output services are therefore possible.
• By the angle of 40 ° between the shaft and piston barrel results in a very compact, lighter and physically smaller motor / pump.
• The laminated piston ring offers important advantages , such as low internal leakage and resistance to rapid temperature changes.
• When pumps are F11 / F12 equipped with optimized control plate for left or right rotation. This increases the Selbstsaug speed and gives a lower noise level.
• The F11 / F12 motors have a very high torque at start-up and at low velocities in .
• The ring gear between the shaft and piston barrel makes the F11 / F12 insensitive to high accelerations and rotational vibrations .
• Robust roller bearings permit high radial and axial shaft loads .
• The F11 / F12 have few moving parts and are very reliable and friendly service .
• The KS , the ring gear and ball bearings , along with the small number of parts that contribute to the very sturdy construction , durability and proven reliability .
