There was a guy awhile back that was very concerned with his freshly removed water pump.
The pics he showed did look cencerning. Looked like there was indeed rubbing going on.
A few other posted...and they all had the same marks.
From what I remember it was finally concluded that the mark is nothing to worry about, that most of us have it...and its most likely a factory mark from them making the block.
Either way, it should be very easy to measure the clearance.

Ok I think I'm just going to pull the trigger and get the flowkooler pump. It has a 2 year warranty from quadratec and that is where I've seen it sold for the cheapest price. If anything goes wrong with it I will just slap a oem back in.

Well my pump and radiator didnt get here yet and I had a small leak in my radiator that was very manageable. Until today when the shaft seal for my water pump decided it didn't want to seal anymore. Since this is my dd I had to go and buy a new stock water pump until I get the flow cooler. Figures doesn't. I love my cherokee but it is not working with me right now.

and this is the icing on the cake for the day. I just walked out my door to find my shipment from quadratec with my new water pump. no radiator yet. got that off ebay.
The maker for the flowkooler water pump changed the design a little bit. All the pics show the plate pop rivited on but this one is welded on. Also comes with different size gaskets for spacing.

well just got the radiator, flowkooler pump, and new theromstat in today. So far so good no leaks! The pump came with 2 different size gaskets. I ended up having to use the thicker one. I tightened up with the stock looking gasket but I could feel it hitting 1# cylinder just a tiny bit when rotated by hand. I will see how it does on my 30 mile trip to work tomorrow.

Im very curious how this set up is holding up. I just moved to NV and the temp is definitely finding my cooling shortcomings and was looking into changing out my water pump.

I have 3 fan conversion, 3 row rad, highflow pump, and t stat housing, love my setup but I wanna try a restricter on my upper hose now to keep it even cooler and balance the temps better
Also just drove from va to fl and back

The flowkoolers now have a machined aluminum impeller and not the riveted on plate like before. Much better design, just put one on a couple weeks ago and works great.

The technicalities of a FlowKooler debate will develop into a conversation of thermal physics. Some fellows on here can explain it like a textbook, but in the 4 years or so I've been on here I've heard that it's important for coolant to:
1) flow fast enough that it has sufficient pressure to make it througout the cooling system
2 ) not have too much flow so that it has time to release/radiate heat through the... radiator.
I've also heard such a variety of reviews and rumors about FlowKooler that as a conservative consumer I'm inclined to stick with stock. A rubbing fan blade should never happen and a thicker gasket shouldn't be the solution. It really is a simple device and I think you'll find better results with a three-row brass or aluminum radiator.

You will run even hotter if you do that, any restriction added anywhere in the cooling system will reduce overall efficiency. It won't 'balance' ****, you will just run hotter.

My 'high-flow' pump looks just like stock, with a 'disk' spot welded on the backside of fins.
Also a high-flow thermostat and housing. New 2 row rad.
Works good for driving in soft sand.
The most effective mod was the fan clutch from a V8 Grand. It made a big difference in keeping temps steady with hard driving and while stop-and-go with AC on.
