🔍 Key Concepts

• Proper procedure for adjusting a packing gland after installing new spiral packing • The relationship between packing tightness, cooling/leakage, and shaft wear • What is typically checked while the pump is running under normal operating conditions after repacking

💭 Think About

• What happens to the packing and gland tightness once the pump starts running and the packing "beds in"? • How much leakage is normally desired from a properly adjusted stuffing box, and why is zero leakage usually not the goal? • Which choice describes a procedure that allows you to fine-tune the packing adjustment under realistic operating conditions?

✅ Before You Answer

• Verify which option allows checking the packing while the pump is running at normal pressure and temperature • Eliminate any choice that would lead to no control of leakage or excessive compression right after installation • Focus on the option that best prevents overheating and rapid wear of both the packing and the shaft/sleeve
