The chemically-resistant series N 840.3 diaphragm pump is a single- and double-head,
dry-running device used in a wide range of laboratory applications.
It transfers and pumps down without contamination.


Quiet and compact, the heart of these very compact pumps is a KNF structured diaphragm.
This patented diaphragm was stress-optimized using the Finite Elements method.
As a result, the pumps are smaller while increasing the service life of the diaphragm. 
Additionally, LABOPORT vacuum pumps are designed to tolerate occasional liquids drawn into
the pump system without damage, making them ideal for a wide range of laboratory applications
including: rotary evaporation, filtration, vacuum ovens, and more.
