LABOPORT® N 820 G CN Diaphragm Vacuum Pump

Diaphragm Vacuum Pump LABOPORT® UN 842.3 FTP

SKU: N/A Categories: ,

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 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

 

Technical features:
 100% oil-free transfer
 Pure transfer, evacuation and
compression
 Highly compatible with vapors and condensation
 Chemically-resistant
 Therefore suitable for highly aggressive or
corrosive gases and vapors
 Maintenance-free
 Environmentally friendly
 Gastight, leakage rate approx. 6 x 10-3 mbar x l/s,
not tested in serial production
