Problems of Centrifugal Pumps
- Cavitation—the net positive suction head (NPSH) of the system is too low for the selected pump
- Wear of the Impeller—can be worsened by suspended solids
- Corrosion inside the pump caused by the fluid properties
- Overheating due to low flow
- Leakage along rotating shaft
- Lack of prime—centrifugal pumps must be filled (with the fluid to be pumped) in order to operate
- Surge

Famous quotes containing the words problems of, problems, centrifugal and/or pumps:
“In many ways, life becomes simpler [for young adults]. . . . We are expected to solve only a finite number of problems within a limited range of possible solutions. . . . It’s a mental vacation compared with figuring out who we are, what we believe, what we’re going to do with our talents, how we’re going to solve the social problems of the globe . . .and what the perfect way to raise our children will be.”
—Roger Gould (20th century)
“More than a decade after our fellow citizens began bedding down on the sidewalks, their problems continue to seem so intractable that we have begun to do psychologically what government has been incapable of doing programmatically. We bring the numbers down—not by solving the problem, but by deciding it’s their own damn fault.”
—Anna Quindlen (b. 1952)
“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)
