I have a simple, practical engineering question.
I'm trying to design a hot water circulation system with a constant flow rate of 1.3 L/min. I'm having trouble finding any pumps that will do the job at the temperature (80-100C) for a reasonable cost.
Essentially, I'm trying to Development of a Consistent and Reproducible Porcine Scald Burn Model
Does anyone know:
- Where to search for for reliable, inexpensive, high-temperature water pumps? I tried McMaster Carr, but they didn't have anything that fit the bill.
- Another way to adjust the flow rate? I thought a nozzle might work, but I'm worrying about too much back pressure damaging the pump, or worse, that a restricted area wouldn't even reduce the flow (RTT)?
