Pump has grounding and bonding lugs

I’ve searched and don’t think this question has been asked. My pump has a grounding and separate bonding lug. Pump bonding lug is on the plastic pool housing which would be for the water. Also my pool is a resin top and bottom with titanium walls. But will still need to ground and bond the pump and pool water.

Here is my thoughts, let me know if this would work.

Attacked #8 grounding wire to the pool seam and run around the diameter along the outside of pool. My pool skimmer doesn’t have a hole for the bonding plate but was going to drill and add that. So I was thinking after going around the pools diameter. Connect the to skimmer bond lug, go from there and tie into the bottom the seam wire (to complete the circle around the pool) and back to the pump connecting to the pump bonding lug (in the plastic pump housing) and then finish it off at the pumps ground lug.
Would this set up work? Do I need to even install the bonding plate at the skimmer and just run directly from around the pool to the pump bonding lug and grounding lug? Would it be best to install a grounding rod or even run 2 ground wires around the pool as a bonding wire for the pump / water?

Tell me how y’all would do it?
 

Bonding and grounding have different purposes and are implemented differently.

You do not connect the pool bonding grid to any electrical grounds.

 
I’ve attached pictures of the bonding lug and grounding lug. I understand the bonding concept, but I don’t think I need to bond to the bonding lug at the bottom of the pump basin only (being plastic). Or is this so I don’t have to install the skimmer bonding kit?

Would it be best to ground the ground lug at the back of the pump to a grounding rod? Maybe also run a 2nd line from the pool seam to the pump and grounding rod?

This bonding lug on this plastic housing is throwing me off and don’t think just that is a proper bond. I maybe wrong though

What model pump are we discussing?

This is the bonding lug for the pump that needs to be connected to your pool bonding grid.

Do not connect the bonding grid to electrical grounds.

That looks like it is there to give you a water bond. It also gets connected to your bonding grid.

So, If I connect to both bonding lugs on the pump (as shown in the picture in housing basin and on top of pump) then I would not need to drill into the skimmer to bond the water there, correct? Since technically the skimmer and pump basin lug are basically bonding the water, while on the same path (line / direction of flow) before it reaches the metal of the pump.

Correct.

This in an above ground pool?

Will there always be a water column between the pump and the pool with the pump off?

If yes, then the water bond at the pump is sufficient.

If no, then you need a water bond at the skimmer to ensure the pool water is always bonded with the pump on or off.
