Flow rate of up to 19 m³/h per pump head and a discharge pressure of up to 1200 bar.

The LEWA Ecoflow is a hydraulically actuated diaphragm metering pump that provides numerous advantages over comparable pumps.

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. Each ecoflow diaphragm metering pump is equipped with the patented DPS diaphragm protection system and produced in Germany.

Fully compliant to API 675 for oil and gas industry applications with proven worldwide experience.

A flowrate of up to 6 m³/h per pump head and a flow rate of up to 500 bar.

The first choice for pharmaceutical and food production pumps.

Stringent process technology requirements apply in the production of food and pharmaceuticals – which makes our tried-and-tested LEWA Ecoflow diaphragm metering pump in sanitary/hygienic design ideally suited to such applications.

The sanitary/hygienic design combines the strengths of Ecoflow, such as extreme metering accuracy and absolute reliability, with special adaptations for use in hygienic conditions, such as minimal dead space and polished surfaces. All surfaces of the pumps are mechanically polished (1.4571: RA < 0.8 µm) or electro-polished (1.4435: RA < 0.5 µm).

Thanks to the tried-and-tested modular system, Ecoflowdiaphragm meter pumps in sanitary/hygienic design can also be configured with various pump heads and drives for almost all applications as food pumps and pharmaceutical pumps. Each Ecoflowpump is equipped with the patented DPS diaphragm protection system and is produced in Germany.

FDA-compliant parts in direct contact with the pumped fluid.

All LEWA Ecoflow diaphragm metering pump parts in sanitary/hygienic design in direct contact with pumped fluid are FDA-compliant. They are also animal fat-free and inspected and documented in accordance with USP Class VI. Guaranteed absolutely hygienic processes and safe use.

Flow rate of up to 9 m³/h per pump head and a discharge pressure up to 500 bar.

The cost-efficient alternative for simple metering tasks.

For pumping simple fluids where leak-free diaphragm technology is not necessary, but precision accuracy and reliability are still required, Lewa can offer the plunger head version of the Ecoflow.

Ideal for metering non-critical fluids, such as water or resin, with the advantage of simple and robust design with low acquisition and operating costs. Available in a modular system with various pump heads, drive units, and motors.

All Lewa plunger pumps provide proven LEWA quality and are manufactured in Germany under stringent quality systems.

Unique suction capacity

The LEWA Ecoflow diaphragm metering pump differs from other pumps due to its unique suction capacity. The undue diaphragm positioning system enables Lewa diaphragm pumps to safely operate with suction pressures as low as 0.1 bar abs, virtually full vacuum. The operating costs for the entire system can also be lower than with other pumps.

Absolutely safe start up

The Lewa diaphragm positioning technology ensures that correct diaphragm positioning is always maintained ensuring safe start-up and operation even in the most demanding process upset conditions. This allows Lewa diaphragm pumps to provide the best operational safety and reliability when starting up your system and longest service life of the diaphragm.

Patented sandwich diaphragm

The Lewa patented sandwich diaphragm is not only extremely durable, but also well-protected. The LEWA DPS diaphragm protection system and a diaphragm monitoring system ensures that the risk of diaphragm failure is minimised. In the unlikely event of failure, the system provides both alarm and containment – with the added advantage of Lewa’s simple, reliable “sandwich” diaphragm technology over traditional double diaphragm systems.

Low maintenance costs and a long service life

All Lewa diaphragm components are designed and manufactured to proven premium standards to ensure low maintenance and operating costs. If the regular maintenance intervals are maintained, the diaphragm pumps can operate for 40 years or more in your production process with numerous such examples worldwide.

Safety and reliability in extreme operating conditions

For Lewa, safety and reliability comes first: The pump is protected from damage, even in the vent of operating errors and extreme upset conditions. Lewa ensures 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.

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.
