LEWA ecoflow®
The all-around talent for virtually all industries.
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 set technological and qualitative standards: Each ecoflow diaphragm metering pump is equipped with the patented DPS diaphragm protection system and produced in Germany.
Good reasons for a LEWA ecoflow®
The LEWA ecoflow is a hydraulically actuated diaphragm metering pump that provides numerous advantages over comparable pumps.
Unique suction capability
The LEWA ecoflow diaphragm metering pump differs from other pumps due to its unique suction capacity. With an absolute suction pressure of up to 0.1 bar abs., it not only provides a wide array of safe installation options. The operating costs for the entire system can also be lower than with other pumps.
Absolutely safe startup
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.
Low maintenance costs and a long service life
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.
API 675‐Standard
The ecoflow series fulfills the internationally valid quality standard of the American Petroleum Institute API 675. It includes all definitions for a diaphragm metering pump in industrial use in terms of its design, construction, performance and acceptance test.
Safety and reliability in extreme operating states
For us, safety and reliability comes first: The pump is not subjected to damage, even after operating errors occur or in extreme 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.
Suitable for virtually all fluids
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.
Patented sandwich diaphragm
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.
Integrated pressure relief valve
A pressure relief valve in the hydraulic part of the diaphragm pump prevents potential overload situations in operation. This valve is individually adjustable and can therefore be adapted to different operating situations.
High energy efficiency
LEWA diaphragm pumps achieve the highest efficiency of all pump technologies. Our ecoflow series also combines high efficiency with low energy consumption.
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.
Worldwide standards
When designing pumps, we adhere to globally valid standards such as VDMA 24284, 24286‐10 and FDA guidelines.
LEWA Smart Monitoring
With digital pumps for more efficiency, system availability and profitability of the entire production.
LEWA Smart Monitoring is a monitoring system consisting of sensors, a programmable logic controller (PLC), an industrial PC (IPC) and data analysis for new and existing pumps. The system determines characteristic values and key performance indicators. There is no intervention in process control or direct contact between the sensor system and the conveyed fluid.
With key performance indicator-based condition monitoring, you detect and monitor operating statuses proactively. You can also optimize the overall output and robustness of your pump and pipe systems. This will increase the efficiency of your entire production plant. You can access the data conveniently via your corporate network. Or you use the LEWA cloud with extended analysis and service offers.

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.
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.
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. This is done by a service technician on site or via remote monitoring.
Heating and cooling jackets
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.
Special design materials
If the process demands it, wetted parts such as pumps heads and valves will be made of special materials such as stainless steel 316/316L (1.4401/1.4404), Hastelloy or Duplex steel and PVC.
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.
Product range
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.

Special pump heads in remote head design
Some tasks in process engineering include the metering 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.
| Type | MR / MV / KV |
| Pressure | 500 bar |
| Flow rate | 19 m³/h |
| Temperature | -70/+400 °C |
| Viscosity | 100.000 mPa∙s |
| Operational capability | Remote pump heads can be installed on all LEWA ecoflow metering and process pumps and on all LEWA triplex metering and process pumps. |
