Creating Fluid Solutions LEWA MICROFLOW-METERING PUMPS FC The microflow-metering pump FC for pressures up to 400 bar has been developed especially for laboratories and pilot plants, where process safety and a broad range of applications are very important. ■ Stroke length infinitely and linearly variable from 0 to 10 mm while pump stopped or in operation; with manual adjustment (scale division 0.1 mm) or with pneumatic or electric actuator ■ Long life through solid construction, best materials, oil-bath lubrication of all moving parts, weather and splash protection ■ Pump head versions: diaphragm, plunger > D1-502en ■ 08.2011 ■ Subject to change without notice ■ Printed in Germany

LEWA microflow-metering pumps FC Simplex metering pump FC 1 with manual stroke adjustment; diaphragm pump head Simplex metering pump FC 1 with pneumatic stroke actuator PHV-C; diaphragm pump head Features: Solid, statically sound bearings for all power transmitting parts Positive spring return eliminates play High plunger acceleration at part-stroke E limination of play, constant front dead center and high acceleration of plunger improve metering accuracy of small metering rates at part stroke M ethod of operation: The drive rotates, via the worm gear, the eccentric shaft and thus initiates the...
