I have a new setup and am a little worried its too big.
Its a davies craig ewp110, so it flows 110litres a min.
I just wondered if thats too fast for the rad to cool the water, the outlets on the pump are 32 shrinking straight away to 25mm with a drop to 19mm where it enters/exits the rad.
The rad is 800x500x30 and i think theres about 7L of fluid in the system.

Just wondered what your thoughts are?

I think a smaller/slower pump will be better???
Any1 got any advice?

 

Heres a pic of the old pump/pipe vs new pump/pipe lol



The pumps meant for engines.

 

Water flow is good. Poor flow is bad.

And even if the pump is capable of what they claim, through smaller pipework flow will be less.

 

Ive kinda decided to fit it and see what happens lol.

Ive thought that too fast through the rad and it wont have time to cool it but too slow through the cooler and it wont cool the air enough...

Trial and error i guess lol.

 

Nope, more flow is better.

 

Lol. Oh ok. Then ive got plenty.

 

If the water is circulating quicker although it passes through the rad quicker it also passes through the cooler quicker. It doesn't get chance to be warmed/cooled as much.

More flow is better.
