hp-Technik VBGRG-D-2-20-HC/H1-So oil pump

Technick VBGRG-D-2-20-HC/H1-So gear pump has a built-in safety (bypass) valve. The principle of operation of hpTechnick VBGRG-D-2-20-HC/H1-So the rotation of two gears with internal engagement, where the rotor (the driving 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. hpTechnick VBGRG-D-2-20-HC/H1-So oil burner pump technical data: Flow rate: max. 6700 L/h Maximum pressure: up to 40 bar Minimum permitted suction pressure: -0.6 bar Warning: gas release may occur even at -0.4 bar Maximum permitted suction pressure: 5.0 bar Maximum allowable pump speed: 2800 RPM at 50 Hz Temperature: up to 150 °C Permissible test pressure: max. 60 bar with mechanical seal removed (when the shaft outlet is sealed)
