Question

With reference to solar water pumps, consider the following statements:

1. Solar power can be used for running surface pumps and not for submersible pumps,

2. Solar power can be used for running centrifugal pumps and not the ones with piston.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Answer 1

Correct option is (d) Neither 1 nor 2

• Some solar submersible pumps use a centrifugal mechanism as a surface pump, While others use a positive displacement mechanism. So that means statement#1 is WRONG, and second#2 is partially correct.
• Further internet search reveals existance of solar powered piston pump systems that can pump water from a well and delivers it to an elevated Storage tank. #2 is wrong.
