March 5, 2009 - The KNF FMM20 solenoid-driven diaphragm pump for metering liquids is factory calibrated to dispense accurate volumes at 20 µl/stroke or can otherwise be customized by KNF for calibration to any specified dosing between 5 µl/stroke and 25 µl/stroke. Users 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.Available materials for head components include PP/EPDM, PP/FFPM, or PVDF/FFPM. Pumps can be mounted easily in any position using manifold, hose barbs, or threaded ports and value-added accessories include pressure control valves, pulsation dampeners, and other options allowing for customized solutions to meet particular application needs.
