Pompe à huile hp-TechnikPON7-I-L-4-25

The Technick PON7-I-L-4-25 gear pump with internal gearing of the PON series has a built-in safety (bypass) valve and an integrated filter for fuel liquids. Technick PON7-I-L-4-25 technical data: Flow rate: 90–320 L/h Maximum pressure: up to 40 bar Minimum allowable pressure at suction port: -0.2 bar Maximum allowable pressure at suction port: 5.0 bar Maximum allowable rotational speed: 2800 RPM at 50 Hz Temperature: up to 150 °C Permissible test pressure: max. 60 bar with mechanical seal removed (when the shaft exit opening from the housing is sealed) The principle of operation of the hpTechnick PON7-I-L-4-25 pump is the rotation of two gears with internal engagement, where the rotor (drive gear) engages with the driven gear, which is internal to the rotor. The driven gear is mounted on a pin, which is located in the pump cover and is mounted eccentrically to the rotor axis. The displacement of the two gears fills the crescent-shaped dividing element. During the operation of the pair, when the teeth of the gears leave the engagement, the process of suction of the working fluid occurs, and then pushing it to the other side of the separation element, and when the teeth of the wheels enter the engagement, it is pushed into the discharge line.
