A suction system with a non suction pump is provided to reduce manufacturing cost by substituting an inexpensive circulation pump or a pressure pump for most of goods requiring a suction of a fluid. In a suction system with a non suction pump, a non suction circulation pump or pressing pump is used. A suction type priming water storage tank(20) is located at a location higher than an inlet part of a non suction pump(10). And, a primming water auxiliary storage tank(30) is formed for storing a required priming water after idling at an outlet of the non suction pump.
