Let's carefully analyze the options again for reciprocating pumps compared to centrifugal pumps:
A. Deliver liquid at uniform pressure
Reciprocating pumps produce pulsating flow and pressure, not uniform pressure.
B. Can handle slurries more efficiently
Reciprocating pumps are positive displacement pumps and are better at handling slurries and viscous fluids compared to centrifugal pumps.
C. Are not subject to air binding
Reciprocating pumps can be subject to air binding, just like centrifugal pumps, though less prone.
D. Can be operated with delivery valve closed
Reciprocating pumps should not be run with delivery valve closed, as it can cause damage due to pressure build-up.
The best answer is:
B. Can handle slurries more efficiently
