How to replace the packing in the slurry pump? The first thing we need to determine when replacing the packing is that the packing sealing structure is divided into two types, one is the packing sealing structure, and the other is the impeller sealing structure. The two seal replacement packings are different!

1) Packing seal structure

1. Remove the packing gland (AH is the split packing gland);

2. Use a tool to hook out the filler;

3. When installing new packing, the interface of each packing needs to be staggered;

4. Finally, install the packing gland. Do not tighten the bolts too tightly. After turning on the pump, adjust the tightness of the packing gland according to the amount of water dripping from the packing.

2) AH impeller sealing structure

1. Disassemble the split packing gland;

2. Then use tools to disassemble the packing, here the disassembly sequence is: packing water seal ring packing packing pad (it may not be dismantled);

3. Install new packing: packing pad packing water seal ring packing;

4. Finally, install the packing gland. Do not tighten the bolts too tightly. After turning on the pump, adjust the tightness of the packing gland according to the amount of water dripping from the packing.
