LEWA ecoflow packed plunger pump

LEWA ecoflow®
Packed Plunger Metering Pump Precision Engineering for Your Applications

The LEWA ecoflow packed plunger metering pump offers a cost-efficient solution for fluid pumping, thanks to its sophisticated modular system.

With direct displacement by the plunger, the LEWA ecoflow packed plunger metering pump ensures efficient fluid transfer. This technology allows for easy metering tasks, with a flow rate of up to 9 m³/h per pump head and a discharge pressure of up to 500 bar.

LEWA ecoflow®packed plunger metering pump

The cost-efficient alternative for simple metering tasks.

In many scenarios, using complex diaphragm metering pumps isn't always the most cost-effective option for pumping simple fluids. That's why we offer the LEWA ecoflow packed plunger metering pump as a cost-efficient alternative.

For metering non-critical fluids like water or resin, relying on a simple and robust pump with low acquisition and operating costs is advantageous.

Despite its affordability, we uphold the trusted LEWA quality: Each ecoflow packed plunger metering pump is manufactured in Germany and undergoes rigorous quality assurance. Additionally, we offer a versatile modular system with various pump heads, drive units, and motors.

Discover the Advantages of Choosing LEWA ecoflow® Packed Plunger Metering Pump

The LEWA ecoflow stands as a hydraulically actuated packed plunger metering pump, offering distinct advantages compared to similar pumps.

Pumps with high suction capacity

Unique suction capability

The LEWA ecoflow packed plunger metering pump 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. The operating costs for the entire system can also be lower than with comparable pumps.

Economic pumps and systems from LEWA

Economical solution for simple tasks

Through the simple but robust plunger technology of the pump head, the ecoflow packed plunger metering pump is the ideal pump for easy metering tasks with non-critical fluids. In addition, it features particularly high energy efficiency and is low maintenance.

LEWA pumps are manufactured according to API standards

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.

High-quality materials

All pump parts in direct content with the fluid are made from high-quality materials. Plungers, for example, are made from ceramic oxide.

Worldwide standards

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

Tried-and-tested plunger seal

The LEWA ecoflow packed plunger metering pump uses the tried-and-tested LEWA plunger seals for maximum tight sealing.

Uncover Key Features of Packed Plunger Metering Pumps

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.

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.

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.

Plunger seal with flushing possibility

In order to guarantee a long-life pump and leak-free operation, our pumps have a flushable plung seal. Thus, leaks are removed easily and safely.

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.

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).

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.

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.

Gas Odorization with LEWA Pumps and Metering Packages

Natural gas, oxygen, and nitrogen are odorless but potentially dangerous. This is why these gases are "odorized" with as strong a smelling substance as possible. For more than 40 years, LEWA has been developing systems for the odorization of gases such as natural gases, biogases, and liquefied gases. This process is enormously important, so the odorizing system has to operate precisely and reliably.
