LEWA process diaphragm pumpsLEWA triplex and LEWA ecoflow safe hermetically tight reliable economical up to1,200 bar (17,400 psig)2Technically state-of-the-art:LEWA supplies the world’s biggest Maximum safety:dry run safe, safe against overload and equipped with diaphragm monitoring system.Low life cycle costs:high overall efficiency, low energy consumption and long service intervals.LEWA eco ow process diaphragm pumpsfor high pressure process engineeringLEWA process diaphragm pumps for high pressure process engineering are the standard for tightness in the high pressure range. Here LEWA has set the standards and consistently further develops the diaphragm pump technology.With LEWA process diaphragm pumps even critical, toxic or in ammable  uids can be conveyed safely. Also extremely low viscosity, non-lubricating  uids or abrasive sus pensions are handled with-out any problems. The pressure range goes up to 1,200 bar (17,400 psig).Advantages of LEWA process diaphragm pumps at a glance:Hermetically tight, zero leakageMetal- or PTFE sandwich diaphragms with diaphragm monitoring system Compact monoblock or variable Dry run and overload safeRugged and low maintenance Precise c

The construction principle ensures that the dia-phragm of the pump head always works in the optimum operating range. This explains the extremely high operating safety.Advantage through the patentedDPS (diaphr

agm protection system)Diaphragm pumps are used when zero leakage and operational safety are re-quired, particularly in the case of  uids that are hazardous, abrasive, polluting or sensitive. In order to keep the load on the diaphragm as low as possible, the diaphragm in LEWA eco ow is ac-tuated hydraulically. Together with the DPS (diaphragm protection system), a long diaphragm service life is ensured.Low-wear valves for the widest rangeOperational safety and the risk of break-downs are crucially dependent on the quality of the valves. The valve design is, therefore, tailored to the re-spective application.

Be it for simple or critical, polluting, hazardous, sensitive, highly viscous or abrasive uids.The DPS (diaphragm protection system) ensures that the diaphragm always moves in the optimum operating range. Even external inuences or extreme operating conditions will not affect it. This is what makes the series M900 extremely safe and particularly economical. The extremely long diaphragm service life is a crucial factor in decreasing life cycle costs. Added to this are the benets of the diaphragm monitoring system, which signals if one of the diaphragms is damaged. Nevertheless, the operated for a certain time, which provides a high level of fail-safety and thus greater availability.Operationally safe thanks DPS (diaphrag

Due to an integrated diaphragm monitoring system in combination with a PTFE sandwich diaphragm high process safety is assured. With this series the use of zero-leakage diaphragm pumps, exceeding the present pressure limits of plastic diaphragms, is considerably more economical than using metal diaphragm pump heads.Advantages of the M800 seriesMaximum pressure 1000bar (14,500 psig)Temperature range -20°C 176Hermetically tight systemHigh process safety due to diaphragm monitoring systemLow life cycle costs due to wear-free plunger seals and long diaphragm service lifeSuitable also for diff
