LEWA ecodos diaphragm metering pump

LEWA ecodos®
Mechanical diaphragm metering pump

LEWA ecodos is a safe, reliable and efficient diaphragm metering pump with mechanical diaphragm actuation that provides many options. It is suitable for virtually all metering and pumping tasks in the low-pressure range. Its multiplexing function enables the use of additional applications such as low-pulsation pumping, recipe metering and mixing tasks.

The ecodos implements a flow rate of 16 to 1460 l/h per pump head and a maximum discharge pressure of 20 bar.

LEWA ecodos®

The optimum solution in the low-pressure range.

Many metering tasks take place in the low-pressure range. In principle, high-pressure pumps such as the LEWA ecoflow can also be used here, though it is usually not efficient to do so.

Another important reason to use mechanically actuated metering pumps is that they protect the pumping fluid from contamination because no hydraulic oil is used in the pump. Many customers prefer mechanically actuated diaphragm pumps, especially for pharmaceutical applications and fluids that react with hydraulic oil.

For this reason, LEWA offers the ecodos series as an efficient, safe solution for pumping fluid in the low-pressure range.

LEWA ecodos diaphragm metering pump

Good reasons for a LEWA ecodos®

The LEWA ecodos is a mechanically actuated diaphragm metering pump with a monitored, 4-layer sandwich diaphragm for low pressures, which has numerous advantages over comparable pumps.

Pumps with high metering accuracy

Exact metering setting

Even in low-pressure conditions, the ecodos diaphragm pump has a precise flow rate adjustment of ± 1%. You can achieve an exact, extensive adjustment range of up to 1:50 thanks to the option of adjusting the pump using the stroke length and/or rotational speed.

Various sizes and equipment

Adjust the LEWA ecodos precisely to meet your requirements: With 6 output ratings, the material variants 316/316L, PVC, PVDF and PTFE and adapted accessories, the diaphragm metering pump is suitable for virtually any pumping task in the low-pressure range.

Integrated control rule systems

Integration into open and closed-loop control systems

Simply integrate the LEWA ecodos into the existing production system: Control the output on the motor side using a frequency converter or with an automatic stroke adjustment. We are happy to advise you to ensure that your pumps run at maximum efficiency.

Hermetically sealed

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.

High level of production reliability

Even if a diaphragm is damaged, continued operation is possible. Therefore, you have sufficient response time for maintenance purposes. This results in a high level of production reliability.

PTFE sandwich diaphragm

The 4-layer PTFE sandwich diaphragm is not only extremely stable and durable. It is also monitored continuously during operation using the patented DPS diaphragm monitoring system.

Options

Multiplex capability

Single drive units with vertically installed motor are space-saving. Alternatively, multiple drive units with identical or different output can be combined for pulsation reduction or recipe metering.

Explosion-proof design

We supply pumps, equipment and systems on request in explosion-proof design for operation up to EX zone 1 . Thus, we guarantee maximum security.

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).

Exactly customized accessories

We pay attention to all the details: All electrical and electronic accessories for your diaphragm metering pump are perfectly tailored to our individual product - from the contact transmitter to the frequency inverter.

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.

Diverse connection geometries

Our pumps are equipped with all common connection geometries such as DIN standard, BASF's high-pressure standard, American ANSI, JIS, or your individual requirements. Customized configurations are possible.

Sanitary & hygienic design

LEWA pumps and systems in sanitary & hygienic design are available for applications that require extremely high purity, such as food production and the pharmaceutical industry.

Complete documentation

In the process of documentation, we consider your requirements and provide inspection records, print samples, diagrams of output characteristics and registration papers on request.

Control and regulation units

With functionally tested controlling and regulating units for frequently occurring standard tasks of diaphragm metering pumps - such as batch metering - your process becomes faster and easier.
