What are Rotary Lobe Pumps?
As a type of positive displacement pump, a rotary lobe pump is unmatched in the precise handling of delicate, high viscosity fluids. The unique lobe mechanism of these pumps consists of two or more rotors which rotate in opposing directions in a pump casing. This design forms a vacuum that allows fluids to be transported throughout the system.
Operation
The core capabilities of the pump is based on a set of rotors which counter-rotate with each other. These rotors, typically formed with 2-3 lobes, come together and turn in a pumping casing. This results in emptiness to be formed between the surfaces of the rotor and the casing. As a result, this leads to a lower pressure which causes a fluid to be sucked and moved towards the pump. The pump then relocates the fluid to the exit port.
