Abstract: Pump/turbine for multiple uses for water, wind, and oil power plants, for Pipeline turbines, Energy plant, metering pump, compressors, for oil-free compressed air, vacuum pumps including the high pressure pumps with unlimited volumes, limited only by the size. Forward and backward with the same performance. This is made possible by the unique Vanpwing (Blade) guide grove, and the centerely located rotational body. Advantages of this method: pumping chamber remains consistently high, High precession possible in the conveying chamber sealing, High vacuum and pressure produced at very low speeds, min. Frictional resistance, no or only min. Wear, reach max. Pressure, vacuum, liter-capacity, up to the physical limit.
