Rotary lobe blowers and rotary lobe pumps belong to the group of dry running positive displacement pumps. There is no need for oil or grease in the compression chamber. Only gear box and bearings, which are separated from the pumping chamber, are oil lubricated.
Air enters the inlet opening into a conveying cell formed by the two rolling pistons in the housing. The cell is then separated from the inlet by the following piston head. The air in the cell is conveyed without reduction until it reaches the outlet, where air with a higher absolute pressure flows from the pressure chamber into the following cell, and must then be discharged. It is during this stage of the conveying that external compression takes place
