157. What type of pump is shown in the illustration
The illustration depicts a triple screw rotary pump, identified by the presence of three intermeshing helical rotors: one power rotor and two idler rotors. This configuration distinguishes it from centrifugal pumps (which use impellers), double screw pumps (which have only two screws), and reciprocating pumps (which use pistons).
