Multistage Centrifugal Pumps
A centrifugal pump containing two or more impellers is called a multistage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts.
For higher pressures at the outlet impellers can be connected in series.
For higher flow output impellers can be connected in parallel.
All energy transferred to the fluid are derived from the mechanical energy driving the impeller.

Famous quotes containing the words centrifugal and/or pumps:
“Travel is like adultery: one is always tempted to be unfaithful to one’s own country. To have imagination is inevitably to be dissatisfied with where you live. There is in men, as Peter Quennell said, “a centrifugal tendency.” In our wanderlust, we are lovers looking for consummation.”
—Anatole Broyard (1910–1990)
“the rusty
Pump pumps over your sweating face the clear
Water, cold, so cold! you cup your hands
And gulp from them the dailiness of life.”
—Randall Jarrell (1914–1965)
