The
new KNF FMM20 solenoid-driven diaphragm pump for metering liquids is factory
calibrated (as standard) to dispense accurate volumes at 20µl/stroke
or can otherwise be customized by KNF for calibration to any specified dosing
between 5µl/stroke
and 25µl/stroke.  Users additionally can adjust calibration in
the field to any stroke within the range. 
This pump is engineered to serve significantly longer than the industry
norm by delivering more than 250 million strokes over its lifetime.  Typical applications include medical
diagnostic equipment, industrial dosing systems, inkjet printers, and fuel
cells, among others.

The
FMM20 pump integrates a noise-suppression system for quiet-running operation
and is flow-tight in both directions (sealed internally for pressures at rest
up to 0.5 bar).  The pump’s diaphragm and
patented valve system contribute reliable and high performance; stable pump
characteristics enable high repeatability over the pump’s entire lifetime; and
low current and power consumption generate energy efficiencies.  The pump can be operated up to 20 Hz to
provide a flow rate from 0 ml/min to 30 ml/min ideally suited for pump priming or
specific operation cycles.
