Odorants - Import export

The barrel pump's universal adapter fits onto container openings of 30 - 70 mm, closing tightly. The container screw joints can be screwed into the container with the 3/4" thread and lock nut. The gas-tight barrel pump enables odour-free transfer. During transfer with normal pumps, it is impossible to prevent vapours escaping into the atmosphere. The gas-shuttle method avoids this. Any vapours produced are returned from the container which is to be filled to the original container via the gas-shuttle pipe. The gas pipe and the liquid pipe are additionally provided with stopcocks. Gas-tight pumps are used for substances that have a strong smell such as ammonia.
