A fluid pump for moving fluid from a first reservoir to a second reservoir is described. The fluid pump comprises a first reservoir containing a fluid, a second reservoir for receiving the fluid, at least one chamber subject to alternating high and low pressure, and an inlet valving device modulating or switching pressures to which the at least one chamber is exposed, causing the fluid to flow into the at least one chamber from the first reservoir when the at least one chamber is exposed to low pressure and causing the fluid to flow out of the at least one chamber into the second reservoir when the chamber is exposed to high pressure.

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.
