Question 285General Subjects - QMED
70% to passWhat type of pump is shown in the illustration? Illustration GS-0144
ADouble screw rotary pump
BDeep well centrifugal pump
CSimplex reciprocating pump
DTriple screw rotary pump
AI Explanation
The correct answer is D) Triple screw rotary pump. The illustration GS-0144 depicts a triple screw rotary pump, which is a positive displacement pump commonly used on vessels for various applications such as fuel transfer, ballast, and firefighting. The three screw-like rotors within the pump housing create a consistent flow of liquid when the pump is operated, making it well-suited for marine applications. The other answer choices are incorrect because a double screw rotary pump has two rotors, a deep well centrifugal pump uses a different impeller-based mechanism, and a simplex reciprocating pump operates using a piston rather than rotating screws.
