Cyclic pump
A Cyclic pump is an apparatus which moves a fluid in a periodic uni-directional direction from one containment system to another while overcoming static conditions that would, without intervention, not move. The intervention predicated by the pump alters pressures, volumes and sometimes temperatures of fluids in such a way that the fluids are transported to other chambers or enclosures, thus "flowing" in a consistent direction, usually having characteristics of pulsation or of uniform motion. Cyclic pumps are generally incorporated into machines to deal with all sorts of fluids associated with that machine's functionality.
