KNF UN820ATP IP44 Diaphragm Pump

The KNF UN820ATP IP44 Diaphragm Pump is a single-head, dry-running device used in a wide range of laboratory applications. They transfer, compress and pump down without contamination. 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, KNF was able to make the pump smaller while increasing the service life of the diaphragm. This pump is 115V.

The KNF UN820ATP IP44 Diaphragm Pump includes:
  • Power Cord
  • Operator's Guide
  • Manufacturer's Documentation
  • 1 Year Manufacturer's Warranty
