LEWA ecoflow ® Diaphragm metering pumps and process diaphragm pumps accurate safe economical innovative

For a wide range of applications: LEWA ecoow in a proven modular system The chemical industry: LEWA ecoow pumps are used, for example, for extraction in high-pressure processes. The petrochemical industry: Used for gentle metering of highly viscous uids in the production of biofuels, for example. The plastics industry: LEWA ecoow pumps are used, for example, for polymerization processes in the manufacture of solar cells. The proven modular system combined with innovative pump head technology The LEWA ecoow metering pump series is based on a proven modular system. Combined with the newly...

The pharmaceutical industry: LEWA ecoow in hygienic design meets the high demands of the pharmaceutical industry for extruding tablets, for example. The cosmetics industry: LEWA ecoow in sanitary design ensures problem-free cleaning in the manufacture of skin care products, for example. The food industry: Sterile and reliable production, for manufacturing gelatin or fruit gums, for example. The new LEWA variable eccentric pump drive types LDF and LDG are closing the loop to LEWA process diaphragm pumps.

For tightness and safety: LEWA ecoow technology The construction principle ensures that the pump head’s diaphragm always works in the optimum operating range. This explains the extremely high operating safety of LEWA ecoow. Low-wear valves for the widest range of tasks Operational safety and the risk of faults are crucially dependent on the quality of the valves. The valve design is, therefore, tailored to the respective application. Prot from our decades of experience in this eld. LEWA ecoow: Advantage through the patented DPS (diaphragm protection system) Diaphragm pumps are used when...

High metering accuracy, gentle delivery The metering pumps provide high metering accuracy and gentle delivery; their stroke can be adjusted (manually, electrically or pneumatically), as can the stroke frequency by means of a frequency inverter. The reproducibility of the settings is better than ±1%. The right material for every uid Stainless steel 1.4571 (316 Ti) is used as our standard material. Other material options such as 2.4610 (Hastelloy) or titanium are also possible. Leakage replenishment valve Any internal leakage in the hydraulic uid area of the piston is balanced through a...

For the most varied requirements: Three LEWA ecoow pump heads Series M900: The secure one for all types of uids M900 is the universal highperformance series with a hydraulically actuated PTFE diaphragm and DPS (diaphragm protection system), which ensures freedom from leaks and operational safety – even in the case of operating errors. Up to 500 bar and + 150 °C For universal use, for all types of uids Highest operational safety Very long diaphragm service life High metering accuracy and wide adjusting range Safe for suction pressure up to 400 bar Recommended for critical, toxic, ammable or...

For all types of uids: Safe M900 diaphragm pump heads Performance overview: Pressure up to 500 bar Flow rate up to 6 m3/h per pump head Temperature - 20 to + 150 °C Viscosity up to 100,000 mPa s For technical data, see page 13 With their diaphragm protection system, the M900 series is not only a universal solution but also one that is operationally safe, 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...

For high pressures and temperatures: The robust M200/M400 diaphragm pump heads Performance overview: Pressure up to 1,200 bar Flow rate up to 1.1m3/h per pump head Temperature + 200 °C Viscosity up to 500 mPa s For technical data, see page 13 With their metal diaphragm and solid construction, the M200/M400 series are the “high pressure pump series” for extreme applications. Long service life: The metal diaphragms receive even ow patterns and are securely protected against overdeection. Nevertheless, the diaphragm can continue to be operated for a certain period, which means high fail-safety...

For unproblematic uids: The tried and tested series K plunger pump heads Performance overview: Pressure up to 500 bar Flow rate up to 9 m3/h per pump head Temperature up to + 400 °C Viscosity up to 100,000 mPa s For technical data, see page 13 Series K plunger pump heads are a tried and tested, safe and economical solution for unproblematic uids. Series K plunger pumps are excellently suited to a whole range of metering tasks. In this construction, the uid conveyed is displaced directly by the plunger, i.e. the plunger and the piston seal are wetted by the uid. A high level of operational...

For low and high metering volumes: Drive units in seven frame sizes In seven sizes and with different gear ratios, a wide range of performance can be covered. Using an eccentric adjustment, the ow rate can be set very accurately over a wide range; for additional stepless speed regulation, the LEWA range includes frequency inverters. Available as a single drive unit with a compactly mounted vertical motor Multiple drive units that can be combined with the same or different performance Electrical, pneumatic or manual stroke adjustment Low maintenance costs, long maintenance intervals High...

For optimum conguration: The drive units options A common oil bath: LEWA ecoow multiple pumps manage without rotary shaft seals between the elements. Drive options Standard motors with IEC or NEMA connections With or without hazardous area protection Available with frequency inverters All types of special drives LEWA ecoow offers a wide range of very different valve designs. Stroke adjustment options Valve designs The drive units can be operated with a constant stroke length or with an adjustable stroke. This can be done manually, electrically or pneumatically. LEWA ecoow offers a wide...
