Working Principle of Lobe Pump

Twin-Rotary pumps are multi-functional and bi-directional positive displacement pumps, produced with fine technology. The manufacturing engineering and precision of the pumps approach the advanced level of the world. Rotary pumps use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium.
