ecoflow® packed plunger metering pump

LEWA ecoflow®packed plunger metering pump

The cost-efficient alternative for simple metering tasks.

It does not always have to be expensive: In many cases, the use of complex diaphragm metering pumps is not cost-effective when pumping simple fluids. Therefore, we provide the LEWA ecoflow packed plunger metering pump as a cost-efficient alternative.

Therefore, for metering non-critical fluids, such as water or resin, it is advantageous to rely on a simple and robust pump with low acquisition and operating costs.

Despite lower costs, we of course provide you with the tried-and-tested LEWA quality: Each ecoflow packed plunger metering pump is produced in Germany, where it goes through all stages of quality assurance. Of course, we also rely on the tried-and-tested modular system with various pump heads, drive units and motors.

Good reasons for a LEWA ecoflow® packed plunger metering pump

The LEWA ecoflow is a hydraulically actuated packed plunger metering pump that provides numerous advantages over comparable pumps.

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.

Unique suction capability

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.

Economical solution for simple tasks

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.

API 675‐Standard

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.

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.

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.

Product range

With a selection of various pump heads, the LEWA ecoflow plunger metering pump covers a large 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.
