Hydraulic pumps most commonly used in steering systems are of the __________.

🔍 Key Concepts

• Types of hydraulic pumps commonly used in marine steering gear • Differences between positive displacement pumps (like piston, screw, and lobe) and non–positive displacement pumps (like volute/centrifugal) • Why steering systems need high pressure and precise control rather than just high flow

💭 Think About

• Think about which pump type is best for producing high pressure at relatively low flow with very accurate directional control for a rudder • Consider which pump types are most often associated with centrifugal flow versus positive displacement in general marine systems • Ask yourself: in a steering system, do we want a pump that can tolerate some slip and variable pressure, or one that must move a fixed volume per stroke/revolution?

✅ Before You Answer

• Identify which option is a centrifugal (non–positive displacement) pump commonly used for general water circulation, not for steering hydraulics • Identify which options are positive displacement pumps and consider which one is most often paired with variable delivery and directional control valves • Verify from your notes which pump design is specifically named in typical hydraulic steering gear diagrams and descriptions
