Technical Specification Sheet (NEW)

KNF UN840.1.2FTP IP44 Diaphragm Pump

The 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.

The KNF UN840.1.2FTP IP44 Diaphragm Pump includes:
  • Power Cord
  • Operator's Guide
  • Manufacturer's Documentation
  • 1 Year Manufacturer's Warranty
