Hey there kushextender!
The main idea is to use a standard submersible pump for providing the water cycling action, and combine with a peristaltic pump to achieve vacuum.
The inlet is simply the top of the cylinder, the same place you would normally connect a pump. The outlet should be at the bottom of the cylinder, so that water must flow the entire length before being heated again.
You can think of it as two systems:
Water Cycling:
Cylinder Inlet > Cylinder > Cylinder Outlet > Heating Reservoir > Submersible Pump > Cylinder Inlet
Vacuum Provider:
Heating Reservoir <> Peristaltic Pump <> External Reservoir
Intuitively the temperature probe should be as close to the penis as possible, so that any heat loss between the heating reservoir and cylinder is measured and accounted for.
A peristaltic pump allows for very precise control over the water cycling system’s pressure, without needing a complicated sealing system. There isn’t much easily-readable research online for their capabilities to hold a vacuum, however this can be easily tested without building the entire solution. My research leads me to believe that it will hold much more of a vacuum than is necessary for this to be effective.
I expect the challenges here are:
- Finding a / verifying that the submersible pump can work under vacuum pressure.
- Vacuum-sealing wires for the submersible pump & heating element.
- Vacuum-sealing the temperature probe in the cylinder.
