New Piston Diaphragm Pumps

The operating range of the new Seybert & Rahler (Germany) piston diaphragm pumps for the series 510.1 is between 65 l/h to 1300 l/h at up to 200 bar and for the series 511.1 from 100 l/h to 1900 l/h at up to 220 bar. With these performance data, the new piston diaphragm pumps are qualified for a wide range of applications including the petrochemical industry. Due to the variable possible combinations, the pumps can also be adapted for many other application areas.

The new 510.1 and 511.1 stroke mechanisms are the basis of these new series which have been designed as variable eccentric drives. The stroke can be continuously adjusted here from 0% to 100% using a hand wheel or an actuator. In doing so, the repeat accuracy is below 1%.

Among other features the new 5series is equipped as standard with a high quality material multi-layer diaphragm which guarantees reliable diaphragm rupture detection.

In order to enable use in the crude oil conveying and processing industry, these pumps are also option available on the one hand for the explosion-protected area as well as in accordance with the API standard 675.
