The non-clog pump which permits solid matter to pass out with the liquid sewage, is A. Centrifugal pump B. Reciprocating pump C. Pneumatic ejector D. None of these

Centrifugal pump
Reciprocating pump
Pneumatic ejector
None of these

The correct answer is: A. Centrifugal pump

A centrifugal pump is a type

of pump that uses centrifugal force to move fluids. The fluid enters the pump through the center of the impeller, which is a rotating disk with blades on it. The impeller spins the fluid, causing it to move outward and up the pump casing. The fluid then exits the pump through the discharge port.

Centrifugal pumps are often used to move liquids, but they can also be used to move slurries, which are mixtures of liquids and solids. The solids in the slurry

are not able to clog the pump because they are carried along with the liquid by the centrifugal force.

Reciprocating pumps are another type of pump that can be used to move slurries. However, reciprocating pumps are more likely to clog than centrifugal pumps because the solids in the slurry can get caught between the moving parts of the pump.

Pneumatic ejectors are not pumps. They are devices that use compressed air to move fluids. Pneumatic ejectors are not suitable for moving slurries because the solids in the slurry can clog the ejector.

Therefore, the correct answer is: A. Centrifugal pump
