Corken offers multiple Coro-Flo models to accommodate a wide range of differential pressures and capacities. Initially developed for filling propane cylinders, the Coro-Flo has since become popular in various applications, especially where volatile liquid transfer is required. It is widely used as a vaporizer feed pump, aerosol propellant pump, and propane cylinder filling pump, and is also well-suited for light liquids like gasoline, solvents, and light oils, as well as liquefied gases such as ammonia, carbon dioxide, sulfur dioxide, propane, butane, and refrigerant gases.
