What type of pump uses a propeller or row of blades to propel liquids axially along the shaft?
A) Axial pump
B) Rotary pump
C) Centrifugal pump
D) Reciprocating pump
Answer: A
Explanation: A) Correct. An axial pump uses a propeller or row of blades to propel liquids axially along the shaft (as opposed to centrifugal pumps that use an impeller to force liquids to the outer wall of the chamber).
B) Incorrect. A rotary pump moves liquids by rotating a screw or a set of lobes, gears, or vanes that trap the liquid and physically push it through the pump.
C) Incorrect. A centrifugal pump uses an impeller on a rotating shaft to generate centrifugal force, which is converted to pressure in the volute to move liquids.
D) Incorrect. A reciprocating pump uses the inward stroke of a piston or diaphragm to draw (intake) liquid into a chamber and then uses an outward stroke to positively displace (discharge) the liquid.
