The chemically-resistant N840.1.2FTP diaphragm pump is a two-stage, oil-free device used in a wide range of laboratory applications. These pumps transfer and pump
down without contamination.
The heart of this very compact pump is a KNF structured diaphragm. 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 and improving performance.
