Q

Positive displacement, helical gear pumps are well suited for pumping oil because __________.

🔍 Key Concepts

• Positive displacement pumps vs. centrifugal pumps when handling viscous fluids like oil • How helical gear pump tooth shape affects flow characteristics (smoothness, sealing, suction) • Meaning of self-priming and suction lift in pump operation

💭 Think About

• Which property of oil (for example, viscosity) makes a certain pump feature especially useful? • Look at each choice and ask: does this describe a real, well-known advantage of helical gear pumps, or does it sound like a distraction? • For gear pumps, what feature mainly helps them move fluid without needing to be primed each time?

✅ Before You Answer

• Verify which pump types are commonly described as self-priming and able to handle high suction lift • Check whether design clearances in gear pumps usually need to be tight or loose to work well with oil • Consider whether extreme tooth angles or stuffing boxes are standard, defining advantages of helical gear pumps for oil service
