ecodos® mechanical diaphragm pump

LEWA ecodos®

The optimum solution in the low-pressure range.

LEWA specializes in low-pressure mechanical diaphragm metering pumps, safeguarding against fluid contamination with the oil-free ecodos series.

This makes them perfect for sensitive applications like pharmaceuticals, where purity is paramount. While high-pressure pumps like LEWA's ecoflow are an option, the ecodos series offers a more efficient solution tailored for low-pressure metering tasks. Customers seeking reliable and clean metering technology find the mechanical actuation of LEWA diaphragm pumps ideal for their needs.

Discover the Benefits of LEWA ecodos®: Your Low-Pressure Mechanical Diaphragm Metering Pump Solution

The LEWA ecodos stands as a mechanically actuated diaphragm metering pump, featuring a monitored, 4-layer sandwich diaphragm designed for low pressures. It offers numerous advantages over comparable pumps.

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.

Different pump types with specific equipment

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.

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.

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.
