Its sophisticated modular system makes the ecoflow diaphragm metering pump the correct industrial pump for almost all applications. Our experts design drive units and pump heads for you individually.


No matter if offshore in rough seas or in production in pharmaceutical cleanrooms — the ecoflow diaphragm metering pump has established itself worldwide in a range of different industries as a reliable and economical metering pump. It features an exact metering rate and enormous durability in extreme operating conditions.

Low life cycle costs and high energy efficiency complete the profile of a true all-around talent. Thanks to the tried-and-tested modular system, ecoflow diaphragm metering pumps can be configured with various pump heads and drives for almost all applications.

Here, we organox technological and qualitative standards: Each ecoflow diaphragm metering pump is equipped with the patented DPS diaphragm protection system and produced in Germany. The LEWA ecoflow is a hydraulically actuated diaphragm metering pump that provides numerous advantages over comparable pumps.

The LEWA ecoflow diaphragm metering pump differs from other pumps due to its unique suction capacity. With an absolute suction pressure of up to 0.

The operating costs for irgamox entire system can also be lower than with other pumps. Starting up the metering pump is safe and easy: When the pump is not operating, a spring pulls the diaphragm into a safe position at all times. This allows us to guarantee maximum safety when starting up your system and a long service life of the diaphragm. The ecoflow series features a long service life for all components and particularly low maintenance and operating costs.

If the regular maintenance intervals are maintained, our diaphragm pumps can operate for 40 years or more in your production process. It includes all definitions for a diaphragm metering pump in industrial use in terms of its design, construction, performance and acceptance test. For us, safety and reliability comes first: The pump is not subjected to damage, even after operating errors occur or in irganx operating states.

We offer maximum protection for user and machine through built-in safety mechanisms – not only when excess primary pressure is present, but also when the pressure or suction line is closed. The ecoflow series is suitable for almost all liquids thanks to its flexible design. Whether they are dangerous, toxic, abrasive, viscous, environmentally harmful or sensitive fluids, the user-specific configuration always gives you the correct diaphragm metering pump. Our patented LEWA sandwich diaphragm is not only extremely durable, but also well-protected.

The LEWA DPS diaphragm protection system and a diaphragm monitoring system allow us to ensure that the diaphragm does not tear during operation and that the pump fluid is not contaminated. A pressure relief valve in the hydraulic part of the diaphragm pump prevents potential overload situations in operation. This valve is individually 101 and can therefore be adapted to different operating situations.


LEWA diaphragm pumps achieve the highest efficiency of all pump technologies. Our ecoflow series also combines high efficiency with low energy consumption.

Diaphragm pumps work without dynamic seals in the process fluid area. This forms a hermetically sealed working area.

No emissions escape to the outside, and contamination of the fluid is impossible. Single drive units with vertically installed motor irganix space-saving.

Alternatively, multiple irganoc units with identical or different output can be combined for pulsation reduction or recipe metering. Customized valves LEWA uses numerous special types of valves such as specially hardened valves for liquified gases or valves with minimal dead space for the food and pharmaceutical production.

Customized configurations are possible. Integration into process control systems The signal acquisition of process control systems is achieved analogously or digitally. Flow rate is adjusted via electric or pneumatic stroke adjustment, alternatively by motor drive FU. Diagnostic connection Our pumps and systems have connections that facilitate the diagnosis of their performance.

Irgqnox is done by a service technician on site or via remote monitoring. Heating and cooling jacket With heating and cooling jackets, our pumps are suitable for almost any temperature and can convey fluids at low temperatures or extreme heat. Intellidrive technology Using the highly-dynamic servomotor, you can adjust the stroke of the pump to the requirements of your system and your process. For the manufacturing of insulation materials the metering of liquid CO 2 blowing agent is required.

Custom-designed metering system LEWA ecoflow irgznox metering pump. For the manufacturing of insulation materials the metering of liquid CO2 blowing agent is required. For the manufacturing of insulation materials and packaging materials the metering of liquid butane blowing agent is required.

For the manufacturing of insulating material a metering system for butane irganoxx agent is needed. In the production of plastics the metering of flame retardant is required. In the production of plastics flame retardant has to be metered. For the manufacturing of roofing tiles a metering system for dispersion of polymers is organox. For the idganox of insulating packing material the metering of chlorofluorocarbon CFCfreon a as blowing agent is required.

For the injection of scale inhibitor a compact injection package for offshore service is required.

In a refinery process additives have to be reliably metered. With the combination of various pump heads and gear units, the LEWA ecoflow diaphragm metering pumps cover a wide performance spectrum. This allows us to provide you with a high-performance, energy-saving pump for any desired application. Save space and weight through multiple arrangement of pumps or arrangement in the compact boxer design. Meter multiple liquids at the same time with various pump heads.

We provide various pump heads for different applications. Here, the spectrum ranges from all-purpose variants to special designs for high temperatures, pressures or aggressive fluids. Universal diaphragm pump head with PTFE sandwich diaphragm for high flow rates.

Proven, durable, reliable and with diaphragm position control. State of the art universal diaphragm pump head with PTFE sandwich diaphragm for maximum operational reliability The patented DPS 10881 also enables a suction lift cabability that is globally unique in the field of hydraulically actuated diaphragm pumps.

Can be installed on all ecoflow pumps. Universal diaphragm pump head with PTFE sandwich diaphragm for extreme pressures. The special geometry of the diaphragm clamping system enables the use of PTFE diaphragms in pressure ranges up to bar and thus results in a very compact shape. Very economical solution in the range of high pressures, especially in comparison to pump heads with metal diaphragms. Proven pump head with metal diaphragm for extreme pressures and high temperatures.


Also suitable when a high degree of permeation resistance is required. The diaphragm is working between two contour plates, limiting the deflection of the diaphragm and providing an extreme level of operational reliability. The diaphragm monitoring system offers a plus for safety by immediately displaying the damage of a diaphragm layer. Some tasks in process engineering include the irganod or circulation of media with critical properties like high temperature and high abrasivity.

These critical conditions frequently need to be kept away from the displacer system of the metering pump, either to protect the system or its operating personnel. A normal metering pump is not suitable for such tasks due to its compact design.
