For high requirements at low pressures: LEWA ecodos The chemical industry: The petrochemical industry: The plastics industry: LEWA ecodos pumps are used, Used for gentle metering of highly LEWA ecodos pumps are used, for example, for example, for dosing of dye. viscous fluids in the production of for polymerization processes in the manufacture biofuels, for example. of solar cells. Quality has never been so efficient and safe LEWA ecodos diaphragm metering pumps are the ideal safe and efficient solution to meet all your specific metering and conveying application requirements in the low...

The pharmaceutical industry: LEWA ecodos in hygienic design meets the high demands of the pharmaceutical industry for extruding tablets, for example. The cosmetics industry: LEWA ecodos in sanitary design guarantees problem-free cleaning in the manufacture of skin care products, for example. Maximised performance and efficiency - in numerous sectors With its flexible design, the LEWA ecodos series is ideal for a wide range of industrial applications; ranging from alcohol to suspensions. LEWA ecodos offers the highest precision, safety and reliability when handling emulsions or suspensions,...

r For availability, safety and conomie efficiency: LEWA ecodos technology The availability and operational safety of your installations dpends on the quality of the individual components. LEWA ecodos helps to increase availability. With its cutting-edge design, the LEWA ecodos series exhibits numer-ous special diaphragm pump features. It is much more resistant than conven-tional diaphragm systems, more durable, highly pressure stiff and safer. LEWA ecodos has a much wider appli驭cation range and is ideal for all types of fluids, solvents or diffusing fluids. Moreover, LEWA ecodos systems are...

33 The ideal material for each fluid The standard material is stainless steel 1.4571(316Ti). Other materials are PVC, PVDF and electrically conductive PTFE. High metering accuracy, gentle conveying The metering pumps provide high metering accuracy and gentle convey-ing. Precise adjustment of the stroke (manually or electrically) and adjust-ment of the stroke frequency via a frequency inverter are possible. Reproducibility of the settings is better than ±1 %. Robust drive units for continuous operation The LEWA ecodos drive units are designed for continuous operation. Spring-cam drive units...

r For optimum process adaptation: Various designs and options Whether as a single pump, e.g. with heads designed to be CIP/SIP. Or as multiplex pumps, e.g. for recipe metering Or as feed pumps, e.g. for high performance with low pulsation LEWA ecodos series pumps are available in 13 performance ratings and can be combined to form multiplex pumps. The pump heads are constructed of stainless steel, PVC, PVDF or electrically conductive PTFE. With its individual controls and a complete range of accessories, LEWA ecodos can be adapted to any application. And it goes without saying that LEWA...

Drive options The drives are IEC motors of well-known manufacturers. The following drives are fitted as standard: ■ 3-phase motors 230/400V 50Hz or 460V 60Hz ■ Degree of protection IP55, insulation class F ■ Optionally with protection class EExe IIT3 and EExde IICT4 Further motors, voltages and degrees of protection available on request. Valve options Various insert rings for the valve seats of the stainless steel pump heads are available to ensure perfect adaptation to the fluid. ■ PTFE ■ FPM ■ Polyurethane ■ Valve seats made of hardened 1.4122 Control options LEWA supplies complete...

r For extra production safety: LEWA ecodos accessories intelligent accessories make the most of your application or plant. Pulsation dampers Metering pumps work in puises; on each pump stroke, fluid is accelerated and then decelerated. Pulsation dam-pers can be required for two reasons: ■ To reduce excessively high pressure fluctuations ■ To generate a flow rate that is almost continuous LEWA has the expertise as well as the accessories to optimally tailor pumps and installations to one another. Safety valves LEWA safety valves prevent pressure overloads in the pumps and installation....
