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:

  1. 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.
  2. 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)?

Many commercial hot water recirculation pumps will do that. Just grabbed one at random - Grundfoss Alpha1 15 40 130.

I couldn't fetch the page after I ran their calculator. I used temp of 99C and head of 2m. 100C doesn't work in their calculator. Click link then click "view in product center", and fill in form. ALPHA1 circulator pump - heating, cooling, hot water

You also have to edit settings for 60hz.
