Liquid is kept from leaking out at the shaft ends of a helical gear pump by __________.

Question 1 of 27070

Liquid is kept from leaking out at the shaft ends of a helical gear pump by __________.

🔍 Key Concepts

• Helical gear pump construction – how fluid moves and where it can leak along the shaft • Stuffing box or mechanical seal – typical ways pumps seal around rotating shafts • Difference between supporting bearings and sealing devices

💭 Think About

• Which component is specifically designed to prevent liquid from escaping along a rotating shaft, rather than just supporting it mechanically? • In a helical gear pump, where is the most likely leakage path near the shaft, and what traditional device is used there on many marine pumps? • Do overlapping gear teeth primarily control internal leakage between suction and discharge, or external leakage along the shaft?

✅ Before You Answer

• Identify which choice is a shaft sealing device, not a support or structural part • Decide which component is commonly found in pump casing penetrations where the shaft exits • Confirm whether overlapping gear teeth deal with sealing at the shaft ends or with internal meshing between gears
