LEWA ecoflow diaphragm metering pump all around talent

LEWA ecoflow®
diaphragm metering pump

Its sophisticated modular system makes the ecoflow diaphragm metering pump the correct industrial pump for almost all applications.

Whether toxic, abrasive or sensitive liquids – the ecoflow diaphragm metering pump is the first choice for almost all fluids. Our experts design drive units and pump heads for you individually. The ecoflow series implements a flow rate of up to 19 m³/h per pump head and a discharge pressure of up to 1200 bar.

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.

High suction capability of LEWA process 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.

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.

Safety manometer of a LEWA pump

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.

Pumps suitable for a wide range of fluids

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.

Hermetically tight, leakfree diaphragm pumps

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.

Pressure Valves

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.

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.
