LIQUIPORT® Liquid Handling/Dosing Pumps for the Lab

The convenient way to transfer liquids in the laboratory. Stylish, compact, resistant to chemical attack, they prevent contamination of your pumped medium, and provide the longest possible lifetime when pumping corrosive liquids, gases and vapors.

With either local or external control capabilities. External protocols include: 0-10 VDC, Start/Stop via TTL contact, and Output Fault Alarm.

The NF100 and NF300 pumps are available in either polypropylene, PVDF or PTFE head materials, with FFPM valves.

Unit Conversion Tools:

NOTES: Standard continuous performance ratings listed on this KNF website and on KNF datasheets are per head, and based on technical data and test results of nominal units measured at sea level, with water at 70°F (20°C) and a nominal electrical supply as listed, and are for reference only. Multiple-head models, different performance models, cost-effective OEM modifications, and a variety of motor options and different materials of construction are also available. Certified drawings are available upon request. Specifications subject to change without notice. You should always check corrosion resistance charts for compatibility with the medium you intend to pump.
