A MEMBER OF NIKKISO pumps + Systems LEWA MICRFLOW-METERING PUMPS M3, M5, M8: Electronically controlled diaphragm metering pumps for the laboratory zero leakage ■ reliable accurate ■ SIP-able low-maintenance LEWA microflow-metering pumps M3, M5 and M8 have been developed especially for critical laboratory applications and incorporate LEWA's many years of experience in diaphragm pump technology. Proven metal diaphragm technology LEWA microflow-metering pumps M3, M5 and M8 feature metal diaphragms which are designed fatigue-proof, for virtually unlimited service life. The problems of wetted plunger seals are completely eliminated. Complete tightness LEWA diaphragm pump heads are hermetically sealed in both directions, which fulfills the most important laboratory safety requirements and eliminated environmental hazards. 1 © D1-503 en ە 12.2010 Subject to change without notice Օ Printed in Germany

A MEMBER OF NIKKISO pumps + Systems LEWA MICRQFLQW-METERING PUMPS M3, M5, M8: Hydraulic diaphragm actuation The metal diaphragm of LEWA M pumps is completely supported and actuated hydraulically. This design practically eliminates the influence of the operating pressure and pressure fluctuations on the accuracy of the metered flow - especially when compared to mechanically actuated elastomer diaphragms or peristaltic pumps. All-metal pump heads For reliability and long life, the LEWA M pump heads are offered as standard in 316 Ti stainless steel or Hastelloy C. Other materials are available on...

A MEMBER OF nikkiso pumps + Systems LEWA MICRQFLQW-METERING PUMPS M3, M5, M8: Metered flow adjustment via stroke length The displacer volume can be set at the unit accurately in percent and with linear characteristics. The stroke length adjustment allows optimization of stroke volume and stroke frequency to the corresponding application or, in the case of external frequency control, serves as additional ratio setter. Simple operation All controls and indicators are located on the front panel of the LEWA M pumps. The suction and discharge connections for the metered fluid as well as the ports...
