The chemically-resistant series N842.3 diaphragm pump is a double-head, oil-free device used in a wide range of laboratory applications. They transfer and pump
down without contamination.
The heart of this very compact pump is a KNF structured dia- phragm. This patented diaphragm was stress-optimized using the Finite Elements method. As a result, we were able to make the pump smaller while increasing the service life of the diaphragm.
