LEWA ecoflow process pump

LEWA ecoflow®
diaphragm process pump

The ecoflow diaphragm process pump is an advanced pump for high-pressure process technology. It features a variable modular design and provides the right solution for a vast assortment of industrial applications.

The DPS diaphragm protection system ensures maximum process reliability. The diaphragm process pump achieves flow rates of up to 19 m3/h per pump head and discharge pressures of up to 1200 bar.

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.

LEWA ecoflow process pump

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.

High suction capability of LEWA process pumps

Unique suction capability

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.

Pumps and systems in modular design

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.

Safe startup

Absolutely safe and reliable startup

Starting up the process pump is safe, reliable and easy: When not operating, a spring fixes the diaphragm in a neutral position at all times. This ensures that the diaphragm is never damaged due to incorrect positioning when starting up.

Long lifetime

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 regular maintenance intervals are maintained, our diaphragm pumps can operate for 40 years or more in your production process.

Safety manometer of a LEWA pump

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.

Variable eccentric principle

The flow rate can be adapted using the tried-and-tested variable eccentric principle based on a linear relationship with the stroke length.

Patented sandwich diaphragm

Our patented sandwich diaphragm is not just extremely durable, it is also well-protected. The LEWA DPS diaphragm protection system and diaphragm monitoring system report any damage to the diaphragm before it tears and has a chance to contaminate the pumped fluid.

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.

API 675 standard

The ecoflow series fulfills the internationally valid quality standard of the American Petroleum Institute API 675. In this standard, all requirements for a displacement pump in industrial settings are defined with respect to design, construction and performance.

Rugged drive units

Our drive units are extremely rugged and durable. This makes the pumps ideal for use under the harshest conditions.

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.

Worldwide standards

When designing pumps, we adhere to globally valid standards such as VDMA 24284, 24286-10 and FDA guidelines.

Hermetically sealed

Diaphragm pumps work without dynamic seals. This forms a hermetically sealed working area. No emissions escape to the outside, and contamination of the fluid is impossible.

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).

    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.

    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.

    Pumps in boxer design

    You can double the flow rate with the same gear size using a LEWA boxer design multiplex pump. In this process, a drive operates two pump heads located opposite each other.

    CIP and SIP capability

    Many LEWA pumps, systems and units can be cleaned (Cleaning in Place) and sterilized (Sterilization in Place). To carry this out, it is not necessary to disassemble the equipment.

    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.

    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.

    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.
