The innovative and universal metering pumps with Diaphragm Protection System DPS series in proven modular design can be applied in various conditions to meet the needs. With the consistently further developed LEWA ECOFLOW series an optimal, customized design for almost every application can be configured from the abundance of standardized assemblies. Therefore it is possible to offer the already legendary LEWA quality at a marketable price. For special technical requirements which cannot be covered by our modular system we are in the position to offer special solutions based on over 50 years of experience. LEWA ecoflow is the most progressive diaphragm metering pump worldwide and offers maximum safety for production and environment:
- Meet the requirements of API 675 according to the American Petroleum Association and the standards as VDMA 24284, 24286-10, 3A, FDA guidelines.
- Satisfy the grading requirements of food and hygiene.
- Lowest life cycle costs. Lowest maintenance costs.
- Extremely long service life of the sandwich diaphragm (18 months warrantee).
- Simple diaphragm replacement.
- Use of LEWA CMS possible as an option.
- Highest reliability and availability.
- Absolute safe start-up of the pump.
- Patented diaphragm protection system (DPS) Diaphragm monitoring system –safe control of the diaphragm movement.
- Highest reliability even in case of mal-operation or extreme operating conditions such as high suction pressure, closed discharge- or suction line.
- LEWA ECOFLOW PUMP SERIES：
- Meet the requirements of API 675 according to the American Petroleum Association and the standards as VDMA 24284, 24286-10, 3A, FDA guidelines. High reliability and adaptability.
- Satisfy the grading requirements of food and hygiene.
- On the material for parts in contact with the fluid, there are two options to choose from, either stainless steel or PVC. The metering quantity can either be adjusted manually, automatic stroke controlled, and frequency speed controlled on the motor drive.
- In combination with the patented DPS (Diaphragm Protection System), the long service life of diaphgram can be ensured.
- Easy replacement of sandwich diaphragm. The patented 4-layer PTFE sandwich-diaphragm provides increased safety and high-precision metering. LEWA ecodos safety diaphragms have a service life of more than 16,000 operating hours, i.e. two years of continuous operation. Therefore, the warranty period for diaphragms is two years.
- Ecoflow can be added with LEWA CMS Monitor System for great performance。
- Depending on the process requirements, there are multiple pump head connection options to choose from.

- LEWA ecodos diaphragm pumps are characterised by their extremely high metering accuracy. Flow rate fluctuations are less than ± 1% in a stroke length adjustment range of 5:1.
- The patented 4-layer PTFE sandwich-diaphragm provides increased safety and high-precision metering. LEWA ecodos safety diaphragms have a service life of more than 16,000 operating hours, i.e. two years of continuous operation. Therefore,the warranty period for diaphragms is two years.
- The flow rates can be adjusted variably: manual adjustment, automatic stroke adjustment, and frequency inverter.
- Flow rates up to 1.5 m³/hr per pump head. Discharge pressure up to 20 bar.
