Maintenance cost of a ______________ pump for a particular duty is the least?
Correct answer: A. Centrifugal
- A. Centrifugal
- B. Reciprocating
- C. Volute
- D. Gear
Explanation
For a given duty, centrifugal pumps generally have the lowest maintenance cost because they contain few wearing parts and have no reciprocating valves or piston seals. Reciprocating and gear pumps usually require more frequent maintenance.
