LEWA ecoflow sanitary food pump

LEWA ecoflow® sanitary/hygienic
diaphragm metering pump

LEWA ecoflow sanitary/hygienic is the most advanced diaphragm metering pump in the world and offers safety for production and the environment during the production of food or pharmaceuticals.

Our experts design drive units and pump heads individually for your application. The ecoflow diaphragm metering pump in sanitary/hygienic design implements a flow rate of up to 6 m³/h per pump head and a flow rate of up to 500 bar.

LEWA ecoflow® sanitary/hygienic
The first choice among pharmaceutical and food production pumps.

Stringent requirements from a process technology standpoint apply in the production of food and pharmaceuticals. Therefore, we also provide the tried-and-tested LEWA ecoflow diaphragm metering pump in sanitary/hygienic design.

Here, we combine the strengths of ecoflow, such as extreme metering accuracy and absolute reliability, with special adaptations for use in hygienic conditions. Examples of these include minimal dead space and polished surfaces.

Thanks to the tried-and-tested modular system, ecoflow diaphragm 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.

We set technological and qualitative standards here as well: Each ecoflow pump is equipped with the patented DPS diaphragm protection system and is produced in Germany.

Good reasons for a LEWA ecoflow® sanitary/hygienic

The LEWA ecoflow sanitary/hygienic is a hydraulically actuated diaphragm metering pump for hygienic applications in the food and pharmaceutical industry that provides numerous advantages over comparable pumps.

Hygienic Design

Sanitary/hygienic-compliant design

Special requirements apply for use in the production of food and pharmaceuticals: LEWA ecoflow sanitary/hygienic fulfills these with polished surfaces and minimal dead space. All industry-standard certifications are available.

FDA compliant

FDA-compliant parts in direct contact with 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. Thus, we guarantee absolutely hygienic processes and safe use.

Safe pumps

Absolutely safe startup

Starting up the ecoflow pump is safe and easy: When not operating, a spring always pulls the diaphragm into a neutral position. This ensures that the diaphragm is never damaged due to incorrect positioning when starting up.

Suction capability

Unique suction capacity

The LEWA ecoflow diaphragm metering pump in sanitary/hygienic design differs from other pumps due to its unique suction capacity. With an absolute suction pressure of up to 0.1 bar, it not only provides a wide array of safe installation options, but the operating costs for the entire system can also be lower than with comparable pumps.

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

API Standard

API 675 standard

The ecoflow series fulfills the internationally valid quality standard of the American Petroleum Institute API 675. It includes all definitions for a diaphragm metering pump in industrial use in terms of its design, construction, performance and acceptance test.

Safety manometre

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.

Polished surfaces

Surfaces polished mechanically

For complying with the strict sanitary/hygienic standards, all surfaces of the pumps are mechanically polished (1.4571: RA < 0.8 µm) or electro-polished (1.4435: RA < 0.5 µm).

Diaphragm

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 valve

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.

Simple cleaning and sterilization (CIP & SIP)

LEWA ecoflow pumps can be cleaned (cleaning in place) and sterilized (sterilization in place) easily without requiring the system to be disassembled.

Complete traceability of all material products

All material products are completely documented and traceable in accordance with EN 10204 3.1b.

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.

Mixing various fluids

Run multiplex pumps, if desired, with different speeds. Thus, fluids with very different viscosities can be conveyed and mixed cost-effectively using one pump.

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 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.

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.

Minimization of pulsation

Multiple pumps designed for the minimization of pulsation can avoid the use of pulsation dampers. Ideal for perishable or slightly contaminated fluids (CIP/SIP capable).

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.

Pressure and flow monitoring

With the LEWA smart control monitoring system, we ensure permanent monitoring and precise control of flow and pressure in your pump.

Special drive units for clean rooms

For applications in pharmaceutical, cosmetic, and food industry, we supply water cooled special drive units for clean rooms to prevent contamination and dust formation.

Explosion-proof design

We supply pumps, equipment and systems on request in explosion-proof design for operation up to EX zone 1 . Thus, we guarantee maximum security.

Heating and cooling jacket

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.

Product range

With the combination of various pump heads and gear units, the LEWA ecoflow diaphragm metering pumps in sanitary/hygienic design cover a wide performance spectrum. This allows us to provide you with a high-performance, energy-saving pump for any desired application.
