Question

The process of filling the liquid into the suction pipe and pump casing up to the level of delivery valve is called as _________

(a) Filling

(b) Pumping

(c) Priming

(d) Leveling

I had been asked this question in class test.

I need to ask this question from Pumps topic in portion Building Blocks of Dairy Processing of Dairy Engineering

Answer 1

The correct option is (c) Priming

The explanation is: Most pumps are not self-priming. In other words, the pump casing must be filled with liquid before the pump is started, or the pump will not be able to function. In case the pump casing gets filled with vapors or gases, the pump impeller becomes gas-bound and incapable of pumping.
