Which of the following is NOT an identifiable characteristic of a steam reciprocating pump?

AI Explanation
The correct answer is C) Diffuser. A steam reciprocating pump does not have a diffuser as an identifiable characteristic. Diffusers are typically found in centrifugal pumps, not in steam reciprocating pumps. The other characteristics - direct-acting, vertical, and high-pressure - are all common features of steam reciprocating pumps. The other answer choices are incorrect because they are all valid identifiable characteristics of steam reciprocating pumps. Direct-acting and vertical configurations are common, and these pumps are designed to operate at high pressures.
