TASCO Exit Exam • Set 6 Question 30 of 30

How the Framo pump has almost eliminated cavitation for free flowing liquids?

✓

Direct Answer

Option C: Since the suction pipe is eliminated, cavitation is also eliminated for liquids with free flow **Correct answer : Since the suction pipe is eliminated, cavitation is also eliminated for liquids with free flow**

Framo submerged cargo pumps eliminate the suction pipe by being placed directly at the bottom of the cargo tank. By removing the long, tortuous suction piping, the pressure drop is minimized, effectively preventing cavitation for free-flowing liquids.

All Options

A
Volute casing is designed in such a way, that its smoothness avoids cavitation
B
The hydrofoil design of the curved vanes, eliminate cavitation
C
Since the suction pipe is eliminated, cavitation is also eliminated for liquids with free flow **Correct answer : Since the suction pipe is eliminated, cavitation is also eliminated for liquids with free flow** (Correct Answer)
D
The backwards curved vanes eliminate the cavitation

Detailed Explanation & Context

Framo submerged cargo pumps eliminate the suction pipe by being placed directly at the bottom of the cargo tank. By removing the long, tortuous suction piping, the pressure drop is minimized, effectively preventing cavitation for free-flowing liquids.
