A motionless pumping design that reduces operation and maintenance costs, and enhances reliability in three aspects of pneumatics system configuration. A motionless and corrosion-resistant pump which uses the continuous generation of pressure variation push/pull force by relying on the venturi effect induced by a pair of gas ejectors together with an argon pneumatic sub-system.

A looping water device has a container, a barrel body, an inlet pipe, and a switch valve. The container has a major tank and a vacuum tube. A water surface in the major tank approaches a datum plane. The vacuum tube is full of water. The barrel body contains air, is secured inside the major tank, and has a discharge port. The inlet pipe is connected to the barrel body and extends into the vacuum tube. The switch valve is connected between the inlet pipe and the barrel body. The air in the barrel body is compressed by water entering into the barrel body from the inlet pipe. When air pressure exceeds, the water in the barrel body is pushed into the major tank. A differential height between the water surfaces of the vacuum tube and the major tank is kept by the atmospheric pressure.
