Question

Match the pump types in Group I with their key components in Group II. \[ \begin{array}{|c|c|} \hline Group I & Group II
\hline (P) \ \text{Centrifugal pumps} & (1) \ \text{Piston rod}
(Q) \ \text{Reciprocating pumps} & (2) \ \text{Impeller}
(R) \ \text{Rotary pumps} & (3) \ \text{Gear}
(S) \ \text{Impulse pumps} & (4) \ \text{Eductor pipe}
& (5) \ \text{Hydraulic ram}
\hline \end{array} \]

• A. P-2, Q-1, R-3, S-5
• B. P-1, Q-2, R-5, S-3
• C. P-2, Q-5, R-4, S-1
• D. P-1, Q-2, R-3, S-4

Hint:

To solve pump-component matches, recall: Centrifugal → Impeller, Reciprocating → Piston rod, Rotary → Gear, Impulse → Hydraulic ram.

Answer 1

The Correct Option is A

Step 1: Centrifugal pumps.
These pumps use a rotating Impeller to move fluid through centrifugal force. \[ P \Rightarrow 2 \]

Step 2: Reciprocating pumps.
They operate by the back-and-forth motion of a piston → Piston rod. \[ Q \Rightarrow 1 \]

Step 3: Rotary pumps.
These use a rotating Gear (or similar element) for positive displacement pumping. \[ R \Rightarrow 3 \]

Step 4: Impulse pumps.
They include the Hydraulic ram, which uses water hammer for pumping. \[ S \Rightarrow 5 \] \[ \boxed{P-2, \ Q-1, \ R-3, \ S-5} \]
