Astuffing box diameter
Bpitch of the screws
Cdirection of rotation of the screws
Dtype of driving gears
AI Explanation
The correct answer is B) pitch of the screws. The pitch of the screws is one of the main differences between the various types of screw pumps. The pitch, which is the distance between the threads of the screws, determines the flow rate and pressure capabilities of the pump. Different screw pitches are used to optimize the pump's performance for specific applications. The other answer choices are not the main differences between screw pump types. The stuffing box diameter (A) and the direction of rotation (C) can vary, but these are not the defining characteristics that distinguish the various screw pump designs. The type of driving gears (D) is also not a primary differentiating factor.
