Install FlowKooler #1751 all-metal impeller waterpump in 2011 KK 3.7L???

Hi!
I'm pulling my hair out after I've replaced multiple OEM waterpumps due to the glued-on plastic impeller coming loose on the shaft.

Has anybody used one of these FlowKooler all-metal improved units?

1751 1999-2012 Jeep 2002-2013 Dodge RAM 3.7L 4.7L water pump

End overheating in a Dodge Ram. Our hi flow pump for the Jeep and RAM trucks has a CNC machined billet impeller designed with more vanes and a reduced impeller clearance to achieve greater flow rates and higher block pressure.

I'm liking the improved, all-metal, impeller design, but my major attraction lies in the solid mechanical connection to the drive shaft.

Thoughts?? Thx!

The hi-flow CNC is a solid choice.
The Gates replacement also includes a metal impeller water pump.

I had replaced my water pump last year with a Gates metal impellor. No problems so far! I had a plastic impellor on the old one.

Is there any advantage to one over the other- FlowKooler vs. Gates product?? There is about a ~$100 difference in delivered price between them. Also, the FlowKooler product is backordered for awhile.

How is the Gates metal impeller affixed to the drive shaft??

TIA!!
