Oh man what a bummer, I'm really sorry to hear this. Well I can only add I knew I would be going to a Meziere pump with an 8 blade, anti cavitation, axial flow impeller one day, and glad I have no issues so far other than I expect it won't keep up with demand on the hottest days under full throttle conditions, but, we will soon see! I have my hills and routes all planned out for the testing, just need to see 120 deg heat!
.
Yeah but how often are you full throttle for and amount of time? I looked at the blades on the Gates pump on Rockauto.com and compared them to the pics I took of the e-pump before the install, I dont see them being much different other than the e-pump has a closed mounting point of each blade to the drive plate, which should flow better than the gates I was looking at.

That would be towing up hills I guess where you'd see extended 3000 rpms, and also worst case scenario for a head gasket failure. So I think the elec pumps do flow more @ idle and low rpms due to the impeller does have more surface area on the blades. Good eye on catching that. The OEM pump starts to take over and pass the elec pump around 2K and up. I'm guessing they desighned the OEM to be run below 2400 to 2500 rpm except for short bursts of high rpm like passing because the pressure on the hoses and gaskets goes way above normal after that.

Also want to add while doing the testing for coolant pressure I had a "coolant bypass" hooked up and set to pop @ 25 psi and still I was seeing 50+ psi with the OEM pump. But, if you pay attention there is no need to run over 2500 rpm with the torque these engines have drive it like a Diesel not a gasser!!!

It's all about quality. Cheap electronics will burn up and crap out faster than a cheap water pump. Now the question is which parts are readily available at any parts store in the country?
So you're assuming cheap electronics...why? The company has been in business for 50+ years and has a stellar reputation.

BTW I have a New Summit pump for sale in the pic, it was damaged and I can't figure out how to reassemble, and the cover is cracked, but someone may want to use it for spare parts. $20.00 plus shipping and it's yours.

Wow your pump was bad. Maybe summit pumps don’t hold up. Mine was just the wiring. How did it get damaged

Not the pumps fault, I bought an extra, and dropped it or something and took it apart to check it out now I can't get the cover back on, or should I say the brushes...I'm assuming the motor is fine, just the housing cover is damaged.

To the guy that said his pump is making noise. If you're the guy that said he used an impact chisel to take the pulley off it's probably why it's making noise....:unsure:
