chemically-resistant UN840.1.2FTP diaphragm pump is a 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. This pump is 115V.
