Thanks for the responses. I posted here rather than the automotive threads because hyd/fluid engineers typically have much more experience with tiny orifice flow than the car guys.
Clean oil - full flow filter Wix filters which are rated at 25 microns. I know the smallest flake of RTV silicone...
Yes I have all the formulas and no this isn't a school project but this is critical enough that I'd like some expert opinions please.
I'm building a "Racesaver" 305cuin small block Chevy. This is a sprint car series 'spec' motor and I will be documenting it in Engine Builder magazine - hence...
Happy New Year!
Here's an update on this project.
Splitting the loop can't happen. It would require a lot more $$ than the budget has.
B&G pump - the short term coupling failure was due to the way it was being operated. The pump was on the thermostat instead of the heater. Pump will now run...
Moltenmetal - you're right on the erosion - I spent 10 years in slurry pumps so it's a reflex.
We're going to mount the B&G pump on a dedicated mount so it can be properly aligned. Even though it's mounted to the motor, I think there was misalignment that failed the couplings.
They are having...
Thanks folks!!
The original design was 2 separate loops but the guy who put the tubing in (former Marine and CEO of the rescue) got in a hurry and made one big one instead. The original design used the old 40 gallon conventional tank water heater, which finally croaked, and a B&G circ pump...
It's been a few years since I've been on Eng-Tips, glad to see it's still active!
I need some help to determine pump requirements for a PEX tubing loop buried in a concrete floor.

The question is...
