The following systems are configured as simple water pumps or air/gas compressors.

The first system is as simple as I can make it for a small methane compressor for someone using a digesting tank. It is actually about table top size. The boiler/condensor cylinders are the short fat throwaway type propane tanks.

The second pic is configured as a water pump but using the same type setup. It uses the water it is pumping as part of the the heating and cooling system to operate.

The next two systems are setup as pumps and use seperate water systems from what they are pumping. These are much higher power systems than the two above.  They both supply their own pumping action to keep the system going. The lower system is a bit more efficient in it’s operation and slightly more powerfull.
