One disadvantage with the use of rotary lobe pumps is the unsteady displacement process which produces pressure pulsations, specifically in long and rigid pipelines and non-compressible liquids. The result is vibration of pump and piping, which increases the risk of cavitation on the suction side. This article explains the mechanical causes of the unsteady displacement process and a new lobe design is derived and described as a consequence.
