When it comes to the maintenance of our pumps, our standards are quite clear: we like long maintenance intervals and few replacement parts.


Our gas pumps are very durable. Economic efficiency, that is, total cost of ownership of our pumps is important to us, which is why we take this into account in the development of every new gas pump series.


Judge the easy maintenance for yourself by taking a look at our latest three gas pump series.

Maintenance Without Dismantling for the N 922 Pump Series

Emission measurement systems in particular are often difficult to access and long maintenance cycles are therefore an important criterion. Depending on the area of application, only the diaphragm and the valves of the N 922 need to be replaced about once a year. Thanks to the special robust design, this can even be carried out on assembled analysis systems using standard tools, ensuring that the measurement technology remains ready for operation even under extreme conditions.
