Gas Recirculation – Experience is our edge
Consultancy, development and manufacturing from a single source for cost-effective system solutions
In many countries, vapour recovery at petrol stations is required by law. The aim is to recover petrol vapours that escape whilst vehicles are being refuelled and return them to the storage tanks. Modern vapour recovery systems, known internationally as STAGE II, reliably and sustainably reduce hydrocarbon emissions.
Thanks to their higher efficiency and greater convenience for customers, active vapour recovery systems have become the market standard.
The gas recirculation pump as a key component
The gas recirculation pump is crucial for an efficient and trouble-free gas recirculation system. With the MEX gas recirculation pump, Dürr Technik offers a high-quality and extremely reliable solution. Our quality and reliability are confirmed by various certifications: ATEX, TÜV, QS, PTB and CN-EX. Our experts will be happy to advise you. Find a certified service partner for maintenance.
The diagram below shows the main components of a typical petrol vapour recovery system
This is how the petrol vapour recovery system works: The system operates by regulating the ratio between the fuel pumped into the vehicle’s fuel tank and the petrol vapour extracted. This ratio is set to 1:1 (proportionality) and is controlled by a mechanical (1) or electric (2) proportional valve. Systems with speed control (3) do not require proportional valves.
Reliable and cost-effective: MEX round the clock
Statutory requirements and automatic monitoring systems place high demands on the reliability of vapour recovery at petrol stations. This is because, by law, if a problem arises with the vapour recovery system, the operator has only a limited amount of time before the petrol pump is shut down. In Germany, this period is 72 hours. The basis for a gas return system that functions continuously is a gas return pump with a constant flow rate. Dürr Technik has been manufacturing the MEX piston pump, developed specifically for gas return, since 1994. Its reliability and flexibility are demonstrated by several hundred thousand units currently in operation worldwide.
