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.
The LEWA ecoflow is a hydraulically actuated diaphragm metering pump that provides numerous advantages over comparable pumps.
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.
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.
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.
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.
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.
LEWA diaphragm pumps achieve the highest efficiency of all pump technologies. Our ecoflow series also combines high efficiency with low energy consumption.
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.
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.
Save space and weight through multiple arrangement of pumps or arrangement in the compact boxer design. Meter multiple liquids at the same time with various pump heads.
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.
Universal diaphragm pump head with PTFE sandwich diaphragm for high flow rates. Proven, durable, reliable and with diaphragm position control.
|Flow rate||19 m³/h|
|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
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.
|Flow rate||6 m³/h|
|Operational capability||Can be installed on all ecoflow diaphragm metering pumps.|
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.
|Flow rate||1,1 m³/h|
|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.
|Flow rate||1,1 m³/h (M200) 0,8 m³/h (M400)|
|Operational capability||M200 can be installed on all ecoflow diaphragm metering pumps ≤ LDE, 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|
|Flow rate||19 m³/h|
|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.|
