The diaphragm pumps series N 811 are devices of a single head and dry running used in a wide variety of applications for laboratories. They transfer, compress and empty without contamination. The heart of these very compact pumps is a diaphragm structured KNF. This patented diaphragm was extremely optimized using the Finite Element method. As a result, we were able to obtain smaller pumps, but at the same time, with a longer life of the diaphragm. The pumps are available in different versions, with different materials that contact the medium.
