LEWA ecoflow®
The all-around talent for high pressure.
The ecoflow diaphragm process pump is the "big sibling" of the ecoflow diaphragm metering pump. It is the world's most advanced pump of its kind and the right solution for almost all applications in process technology requiring high discharge pressures.
The tried-and-tested modular system makes it possible to combine various pump heads and drive units in variable modular construction with an in-line or boxer design.
The ecoflow ensures dependable use even under the harshest conditions thanks to a patented sandwich diaphragm, diaphragm protection system and high drive unit durability. It is ideal for applications involving virtually any media, even hazardous, combustible, toxic, abrasive, viscous, environmentally harmful or sensitive fluids.
Good reasons for a LEWA ecoflow®
The LEWA ecoflow is a hydraulically actuated process diaphragm pump in modular design and a technological pioneer on the world market.
Unique suction capacity
The LEWA ecoflow diaphragm process pump differs from other pumps due to its unique suction capacity. With an absolute suction pressure of up to 0.1 bar, it provides more than just a wide array of safe installation options. The operating costs for the entire system can also be decreased compared to other pumps.
Modular system
The construction with its tried-and-tested modular system makes it possible to combine various pump heads and drive units in variable modular design with series or boxer design. This allows us to create a process pump that meets your specific needs. We take your performance needs and space requirements into account in the design.
Safety and reliability in extreme operating states
For us, safety and reliability come 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 process pump.
Integrated pressure relief valve
A pressure relief valve in the hydraulic part of the diaphragm pump prevents potential overload situations during 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.
Performance spectrum
With the combination of various pump heads and gear units, the LEWA ecoflow diaphragm process pump covers a wide performance spectrum. This allows us to provide you with a high-performance, energy-saving pump for any desired application.
Installation dimensions
Save space and weight through multiplex arrangement of pumps or arrangement in the compact boxer design. Meter multiple liquids at the same time with various pump heads.
Pump head variants
We provide various pump heads for different applications. Here, the spectrum ranges from all-purpose variants to special designs for high temperatures, pressures or aggressive fluids.
State of the art universal diaphragm pump head with PTFE sandwich diaphragm for maximum operational reliability The patented DPS technology also enables a suction lift cabability that is globally unique in the field of hydraulically actuated diaphragm pumps. Can be installed on all ecoflow pumps.
| Type | M900 |
| Pressure | 500 bar |
| Flow rate | 6 m³/h |
| Temperature | -20/+150 °C |
| Viscosity | 100.000 mPa∙s |
| Operational capability | Can be installed on all ecoflow diaphragm metering pumps. |
Universal diaphragm pump head with PTFE sandwich diaphragm for high flow rates. Proven, durable, reliable and with diaphragm position control.
| Type | M500 |
| Pressure | 350 bar |
| Flow rate | 19 m³/h |
| Temperature | -50/+150 °C |
| Viscosity | 100.000 mPa∙s |
| Operational capability | Metal pump heads (316/316L): can be installed on all ecoflow drive units ≥ LDE Plastic pump heads (PVC/PVDF/PTFE): can be installed on all ecoflow drive units ≤ LDE |
Universal diaphragm pump head with PTFE sandwich diaphragm for extreme pressures. The special geometry of the diaphragm clamping system enables the use of PTFE diaphragms in pressure ranges up to 1000 bar and thus results in a very compact shape. Very economical solution in the range of high pressures, especially in comparison to pump heads with metal diaphragms.
| Type | M800 |
| Pressure | 1.000 bar |
| Flow rate | 1,1 m³/h |
| Temperature | -10/+60 °C |
| Viscosity | 100.000 mPa∙s |
| Operational capability | Can be installed on all ecoflow process diaphragm pumps ≥ LDF. |
Proven pump head with metal diaphragm for extreme pressures and high temperatures. Also suitable when a high degree of permeation resistance is required. The diaphragm is working between two contour plates, limiting the deflection of the diaphragm and providing an extreme level of operational reliability. The diaphragm monitoring system offers a plus for safety by immediately displaying the damage of a diaphragm layer.
| Type | M400 |
| Pressure | 1.200 bar |
| Flow rate | 0,8 m³/h (M400) |
| Temperature | -40/+200 °C |
| Viscosity | 500 mPa∙s |
| Operational capability | M400 can be installed on all ecoflow process diaphragm pumps ≥ LDF. |
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. |
