CHEMCO Exit Exam • Set 6 Question 6 of 30

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

✓

Direct Answer

Option D: Since the suction pipe is eliminated, cavitation is also eliminated for liquids with free flow

Framo pumps, particularly those designed for free-flowing liquids, often eliminate the need for a suction pipe. This removal of the suction line significantly reduces the risk of cavitation, as the liquid flows directly into the pump casing.

All Options

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

Detailed Explanation & Context

Framo pumps, particularly those designed for free-flowing liquids, often eliminate the need for a suction pipe. This removal of the suction line significantly reduces the risk of cavitation, as the liquid flows directly into the pump casing.

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • Advanced Training for Chemical Tanker Cargo Operations (CHEMCO).
