The Automatic operating autoclaves of the AM/../SP12E and SP24 series are pumping and pressure increasing units and provide water under pressure to the various points of use such as, showers, taps, boilers, etc. 
The sets comprise: a self priming pump with direct or alternating current, which takes the water from the storage tank, through a non-return valve which prevents the water, with pump stopped, to flow back into the tank and by the electrical system SP12E/M, which manages the electronic operation of the shutdown and turning off of the pump, when there is lack of water.
