External gear pumps The 1P are external cylinder gears pumps, with compensation of axial games, with a time of rotation and with a conical tree with a stick. They allow to obtain high volumetric yields even at high operating pressure, low level of noise and characterized by a high duration thanks to the load balancing system on driving bushings. They are available with cylinders from 1.1 to 8.0 cm3/lap and with operating pressure up to 230 bar. The hydraulic connection is of the type with BSP threaded attacks.
