Stable and Unstable Centrifugal Pumps
Characteristics of stable and unstable centrifugal pumps
For stable head-flow characteristics the differential head - h - progressively falls with increasing flow rate - q.
For unstable head-flow characteristics the differential head - h - rises to a maximum and then progressively falls with increasing flow rate - q.
An unstable pump may start to oscillate between the two possible combinations of head-flow. The flow rate will modulate and the pipeline vibrate.
It is recommended that centrifugal pumps are designed and operated under stable conditions.
