electric water pump ?

We are building a International 300 utility. We need a electric water pump. What kind are the most reliable? Where can we get one? Any advise would be great. Thanks Al

I use a stainless steel Hypro Aqua Tiger pump. I installed a ball valve in the lower water pipe (John Deere 70) to restrict flow somewhat. If the flow is too much the tractor will run hot due to not enough time in the radiator. Mike
 
(quoted from post at 16:09:16 09/29/14) I use a stainless steel Hypro Aqua Tiger pump. I installed a ball valve in the lower water pipe (John Deere 70) to restrict flow somewhat. If the flow is too much the tractor will run hot due to not enough time in the radiator. Mike

Restricting the water flow can cause localized hot spots (boiling) in the engine and possible detonation in severe cases. The radiator is always full of water reguardless of the flow rate and will cool the engine. There is no time difference, the radiator is always full of water and rejecting heat to the atmosphere thereby cooling the engine.
 
if you have the water flowing too fast through the
rad. the water does not spend enough time in the rad.
to lower water temp.
 
This is an age old argument, generally speaking, heat transfer rules state that faster flow is better because it creates turbulence which promotes heat transfer. Theoretically, extremely high flow resulting in very high velocity could create steam/air pockets which would lower or even stop heat transfer. But this would almost impossible to create with impellor pumps.

The debate will continue.

I was wondering if u have a phone number for the place where u orderd the school bus water pump thank u???!!
 
needs some restriction in order to slow the flow so the liquid has time to absorb some heat from the block,not so much from a rad problem. you may all do as you wish,but yrs of racing proves many issues,total free flow is not the answer.restricted or not,flow could cause hot spots and or voids,but slow gives it time and a chance to pull the water,heat and keep flow even.
 
I have used the meziere pump as well. My concern with the school bus pumps is that they cannot push water against much restriction (cannot build much pressure) and still flow. The other factor is the school bus pump is the flow rate. Your stock water pump will put out 30 to 40 GPM at WOT. The school bus pumps are 2 to 3 GPM (depending on pump). The meziere is 20GPM.

With regards to the "water too fast to cool" sentiment, that is a wives tale typically derived from people removing a thermostat and having the engine subsequently overheat. The people that removed t-stats either forgot or didn't understand that 99% of thermostat installations also BLOCK THE BYPASS when they open. Removing them prevents the bypass from closing, thus the water takes the path of least resistance block into the block and never gets to the radiator...

Thank you Goldsburg for pointing out the bypass.
If faster and faster coolant flow caused over heating. Better not tell the CNSC. The Bruce A reactor design was souped up with high flux density and more heat transport flow per second .When updated to the higher output Bruce B specs. . The exact same reactor core was used with even higher flux density and more beat transport flow for the Darlington reactors .
