LEWA ecoflow process diaphragm pumps for high pressure process engineering Low life cycle costs: high overall efficiency, low energy consumption and long service intervals. Maximum safety: dry run safe, safe against overload and equipped with diaphragm monitoring system. LEWA 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 inflamͭmable fluids can be conveyed safely....

r High performance with minimum foot print: The LEWA drive units LEWA process diaphragm pumps are available in the compact LEWA triplex series and in the segment design LEWA ecoflow. LEWA triplex (monoblock design) LEWA triplex drive units are engineered in monoblock design. ■ Extremely space- and weight saving monoblock design ■ Solid, rugged overall design ■ Extremely smooth and low-vibration operating due to equal eccentric phasing ■ Sturdy friction bearings for eccen-tric shaft and wrist pins ■ Integrated worm gear and vertical flange motor up to G3R size ■ No base frame necessary up to...

r For tightness and safety: LEWA diaphragm pump heads Basic functions, using the sries M 900 as example. 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 patented DPS (diaphragm protection system) Diaphragm pumps are used when zero leakage and operational safety are required, particularly in the case of fluids that are hazardous, abrasive, polluting or sensitive. In order to keep the load on the diaphragm as low as possible, the diaphragm in LEWA...

For all types of fluids: Safe M900 diaphragm pump heads Performance overview: Pressure up to 400 bar Flow rate up to 7 m3/h per pump head Temperature -20 to +150° C Viscosity up to 100.000 mPa s For technical data, see page 13 With its diaphragm protection system, the sries M900 is a uni-versal and particularly fail-safe solution. Be it for simple or critical, polluting, hazardous, sensitive, highly viscous or abrasive fluids. The DPS (diaphragm protection System) ensures that the diaphragm always moves in the optimum operat-ing range. Even external influences or extreme operating...

r Universal with high performance: Diaphragm pump head M500 Performance table: Pressure up to 350 bar Flow rate up to 50 m3/h per pump head Temperature - 50 to +150 °C Viscosity up to 100.000 mPa s For technical data, see page 13 Hermetically tight: Diaphragm pump heads can also be used for critical, toxic or inflammable fluids. The universal series with PTFE sandwich diaphragm; suitable for practically any metering and conveying application. Due to the revolutionary diaphragm position control highest operational safety can be achieved even for fluids difficult to handle, e. g. suspensions...

For high pressure and high performance: Diaphragm pump head M800 Performance table: Pressure up to 1000 bar Flow rate up to 1 m3/h per pump head Temperature - 20 to +80 °C Viscosity up to 100.000 mPa s For technical data, see page 13 The high pressure diaphragm pump heads of the M800 series represent an extension of the proven M500 series with a discharge pressure up to 1000 bar. Due to an integrated diaphragm moni-toring system in combination with a PTFE sandwich diaphragm high process safety is assured. With this series the use of zero-leakage dia-phragm pumps, exceeding the present...

r For high pressure up to 1200 bar: Diaphragm pump heads M400 Performance table: Pressure up to 1200 bar Flow rate up to 1500 l/h per pump head Temperature up to +200° C Viscosity up to 500 mPa s For technical data, see page 13 The high pressure pump series with metal diaphragm for high pressures and high temperatures. Diaphragm pumps with metal dia-phragm are used when high pressures or high temperatures must be handled or when absolute diffuͭsion resistance is required. This series offers extremely high safety standards by limiting the diaphragm deflection in both directions so that...
