What is a Rotary Lobe pump?

Rotary Lobe Pumps, are dry running positive displacement pumps. This means that there is no need for oil or grease in the compression chamber. Only the gearbox and bearings, which are separated from the pumping chamber, are oil lubricated. Two non contacting triple lobed rotary lobe rotors rotate against each other in the compression room.

What type of application use rotary lobe pumps?
