In a fuel cell, a hydrogen and oxygen produces electricity, heat and water as a by-product. A fuel cell consists of two electrodes, an anode and a cathode. A membrane separates them and is responsible for the ion transport.
Hydrogen is supplied on the anode side, oxygen on the cathode side. The hydrogen molecules are split into protons and electrons. The hydrogen protons diffuse through the membrane to the cathode, where they react with the oxygen to form water, thereby releasing energy. It is important that oxygen does not diffuse into the hydrogen loop to prevent explosive conditions. Therefore, hydrogen is injected in a higher quantity. This excess hydrogen shall not be released to the atmosphere because of legal regulations and efficiency reasons. The solution is to recirculate it back to the system inlet.

Dolphin LMs are single-stage vacuum pumps for rough vacuum applications from atmospheric pressure to 100 Torr ultimate pressure. Dolphin LTs are two-stage vacuum pumps and operate from atmospheric pressure to 25 Torr. The Dolphin LM / LT series is available in a total of 13 sizes, allowing an exact match to every process.The operating fluid is usually water, but other liquids may be used if required by process conditions. Dolphin LM / LT liquid ring vacuum pumps may be operated as a simple continuous flow system, or as a partial or total recirculation system.
The pumped medium is trapped between the cylinder and screw chambers, compressed, and transported to the gas outlet.
During the compression process the screw rotors do not come in contact with each other or the cylinder.
Thus, no lubricants or operating fluids are required in the compression chamber.

Today, Busch from Maulburg in the Black Forest in Germany is the world market leader in all areas of industrial vacuum.
The COBRA NC is a series of high-performance and robust dry screw vacuum pumps for demanding applications with maximum flexibility and modularity for process changes. These vacuum generators are in use wherever gases and vapors need to be pumped reliably. The proven, completely dry screw vacuum technology allows the COBRA NC to run without operating fluids in the compression chamber. In practice this means no contamination of the pumped medium, and no environmental emissions. In addition, no costs arise for the purchase, replacement and disposal of operating fluids. Maintenance tasks such as oil changes or filter replacement are no longer required or are reduced to a minimum.
Intelligent, efficient and reliable: The R5 PLUS is the first fully connected vacuum solution from Busch. With advanced control and monitoring functionalities it is ready for Industry 4.0. All relevant parameters can be adjusted and monitored allowing a perfect match to every process.

They have been specifically designed for use in vacuum packaging machines and fast packaging cycles.Robustness and reliability of operation are the outstanding qualities of R 5 rotary vane vacuum pumps. These are just some of the reasons why proven Busch rotary vane technology has long established itself as the industry standard. Over 2.5 million R 5 rotary vane vacuum pumps are in operation worldwide in industry every day.High efficiency and energy-efficient drive units are the outstanding qualities of this product family. The R 5 RD series even achieves the same performance with 20% less energy consumption.
Busch Vacuum Solutions mass spectrometer leak detectors are ideal for testing the tightness of vacuum systems or individual vacuum components and for locating possible leaks and quantifying their leakage rate. The two new leak detectors; TAPIR HL 1102 A and 2216 A, operate with helium or hydrogen as a tracer gas and can detect leaks as low as 5E-12 mbar L/S for helium depending on the test method and test product capability.
The revolution of oil change. The new Oil Drain Valve Kit from Busch. A conventional oil change is always associated with spills and dirty hands. With the Busch Oil Drain Valve, this is a thing of the past. The Oil Drain Valve Kit, specially developed for R5 rotary vane vacuum pumps, comes with a silicone hose with quick-release mechanism, wear-free ball valve, protective cover and stainless steel seal. Only two simple steps are needed to change your oil: insert the silicone hose and turn it. Oil change? Never been easier!
If the counterpressure is too high or if smoke is coming out of the exhaust of your vacuum pump, it is time for a filter change. This will restore your vacuum pump to optimum performance. Our maintenance video shows you how to change the exhaust filters in R5 vacuum pumps. The Busch Genuine Maintenance Kit contains all parts for an efficient filter change. To ensure a long life and an efficient operation of your vacuum pump, we recommend our globally available Busch Service. We can do the whole maintenance and overhaul for you.
If the oil is dirty and/or too thick, it is time for an oil change. This will restore your vacuum pump to optimum performance. Our maintenance video shows you how to change oil and oil filters in R5 vacuum pumps.
Everything you need for an easy oil change is our Busch Genuine Oil, Oil Filters and Oil Drain Valve Kit. To ensure a long life and an efficient operation of your vacuum pump, we recommend our globally available Busch Service. We can do the whole maintenance and overhaul for you.
