A pump is leaking excessively around the packing gland. The operator should first try to?

• A. Replace the packing gland
• B. Call pump representative
• C. Replace pump shaft
• D. Tighten packing gland

Answer: (D)

Tightening the packing gland is the first corrective step because the gland compresses the packing material around the shaft to form the seal. If leakage is coming from the packing area, the most immediate fix is to increase compression by turning the gland nuts a little at a time. Do this in small increments and monitor the pump for signs of overheating or increased friction, since over-tightening can damage the packing or shaft. If tightening stops the leak, you’re done. If leakage persists after correct tightening, then inspect the packing condition and consider replacement or further maintenance.
