Diaphragm Vacuum Pumps and Compressors

KNF Diaphragm Vacuum Pumps and Compressors

Pumps Model PM25770-022

PM25770-022 diaphragm pumps are single-head, dryrunning devices used in a wide range of laboratory
applications. They transfer, compress and pump down without contamination. The pumps are assembly with fine control valve with gauge at suction and pressure side for control desire flow rate and vacuum level.
  • 100% oil-free transfer
