LEWA ecodos sanitary/hygienic diaphragm metering pump

LEWA ecodos®
Premier Sanitary and Hygienic Low-Pressure Diaphragm Metering Pump

The LEWA ecodos metering pump is engineered for sanitary and hygienic applications, offering a safe and efficient solution for both food and pharmaceutical production. With surfaces designed to meet stringent hygienic standards, this diaphragm metering pump is optimized for low-pressure conditions. It features a flow rate range of 16 to 1460 l/h per pump head and can handle a maximum discharge pressure of up to 20 bar. The ecodos sanitary/hygienic model is engineered to minimize dead spaces and ensures ease of cleaning, embodying the perfect blend of performance and hygiene for sensitive metering tasks.

LEWA ecodos®

For hygienic processes in the low-pressure range.

LEWA's ecodos series presents the ultimate sanitary and hygienic metering pump solution, catering to the rigorous standards of food, beverage, and pharmaceutical production. These pumps are engineered with polypropylene or stainless steel heads, ensuring a hermetic seal that protects against contamination. Their easily cleanable surfaces eliminate residues and microbes efficiently, maintaining pristine conditions.

Perfectly designed for low-pressure metering up to 20 bar, the LEWA ecodos pump excels in both aseptic and hygienic environments, delivering unmatched reliability and efficiency. The mechanical diaphragm actuation guarantees zero risk of hydraulic oil contamination, solidifying the ecodos as the sanitary choice for precision metering tasks.

Top Advantages of LEWA ecodos®: Your Sanitary and Hygienic Low-Pressure Metering Pump

Experience the advanced LEWA ecodos, a mechanically actuated diaphragm metering pump, crafted in a sanitary and hygienic design. Its monitored, 4-layer sandwich diaphragm is engineered for optimal performance at low pressures. This pump offers numerous benefits over other pumps in its class, combining clean operation with precise metering capabilities.

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.

Sanitary/hygienic-compliant design

The sanitary/hygienic-compliant design fulfills the production requirements for food and pharmaceutical products: It features the smallest possible dead spaces and polished, easy-to-clean surfaces. Of course, the ecodos holds all industry-relevant certifications, such as EHEDG EL Class I.

LEWA is certified by the US Food and Drug Administration

FDA-compliant parts in direct contact with pumped fluid

All parts of the LEWA ecodos diaphragm pump in hygienic design that come into contact with fluids are FDA-compliant, corresponding to the most important requirements for hygienic processes. They are also free of animal ingredients (AOF) and comply with USP Class VI (87 & 88).

Different Variants

Various sizes and equipment

Adjust the LEWA ecodos precisely to meet your requirements: With 6 output ratings, the material variants 316/316L, stainless steel 1.4435 or PP and adapted accessories, the diaphragm metering pump is suitable for virtually any pumping task in the low-pressure range.

Surfaces polished mechanically

For complying with the strict sanitary/hygienic standards, all surfaces of the pumps are mechanically polished (1.4571: RA < 0.8 µm) or electro-polished (1.4435: RA < 0.5 µm).

Hermetically sealed

The ecodos metering diaphragm pump is mechanically driven (not hydraulically driven). This means that the pumping fluid will not become contaminated due to hydraulic oil or environmental influences.

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.

Complete traceability of all material products

All material products are completely documented and traceable in accordance with EN 10204 3.1. In this way, we ensure maximum transparency and safety for your production process.

Dry-run safe and maintenance-friendly

The pumps are dry-run safe and maintenance friendly. No sliding seals or packages are inserted.

Features of LEWA ecodos®: Leading Sanitary Hygienic Low-Pressure Metering Pump

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.

Frequency converter

The speed control of ecodos diaphragm metering pump is effected precisely by a supplied frequency converter or other variable speed drives.

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.

Electrical stroke adjustment

Adjust the stroke length of your pump exactly to the specific metering task: LEWA pumps can be set fully automated by an electric stroke adjustment with integrated regulator.

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.

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.
