Washing liquids
Certain surface treatment processes in the metal-processing industry require thorough cleaning with washing liquids beforehand. To maintain the optimum cleaning effect and ensure continuity of production, entrained particles and tramp oils must be separated out early. GEA separators can handle this job.
Treatment with separators
In the running production process, GEA separator separate oil and solid particles in a single step. The system convinces through its constantly high cleaning efficiency and substantially reduced washing lye consumption. The life of the cleaning liquid is extended, wear to the machine tools is reduced and the quality of the machined work pieces is enhanced.
Important role in the automotive supplier industry
One branch in which this cleaning process plays an important role is the automotive supplier industry. Deep drawing presses operating with pressing weights of up to 2000 tons are used for the production of car body parts. Local temperatures of up to 2000 °C can occur as a result of the level of pressure and friction between the tool and the work piece. For this reason, so-called drawing oil is sprayed into those areas in which the largest deformations take place. This reduces the level of wear and tear on the expensive tools, and also increases the dimensional accuracy of the components. Before further processing, the components have to be degreased in a series of immersion baths. Tramp oil and metal particles must be continuously removed from the washing lye to prevent renewed grease contamination.
Considerable reduction of disposal costs
Separators from GEA are applied in the treatment of the lye-drawing oil mixture. They ensure that the circulating washing lye always remains clean. At the same time, concentrated drawing oil is recovered in the separating process which is recycled back into the drawing process after being enriched with additives. This means lower disposal costs for the supplier since the oil-free wash water does not have to be declared as special oil and can therefore be disposed of more cheaply.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
Jet pumps
Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.

A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
Closing the loop: key lessons for breweries from OeTTINGER
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
