The role of washing lye in modern metalworking
In metal forming and automotive supplier industries, washing lye plays a critical role in cleaning and degreasing components after machining. For example in the automotive industry deep drawing presses, operating with forces up to 2,000 tons and generating localized temperatures of up to 2,000 °C, require drawing oil to be sprayed onto high-deformation zones. This protects expensive tools and ensures dimensional accuracy of car body parts.
Before further processing, components must be thoroughly degreased in immersion baths. However, tramp oil and metal particles can quickly contaminate the washing lye, leading to recontamination of components, increased tool wear and compromised surface quality. Continuous removal of these impurities is essential for maintaining cleaning efficiency and product quality.
GEA’s solution: Simultaneous separation and oil recovery
GEA separators are seamlessly integrated into your production process, removing oil and solid particles from washing lye in a single step. This ensures consistently high cleaning efficiency, significantly reduces washing lye consumption and extends the life of your cleaning liquids.
Our technology also recovers concentrated drawing oil, which can be enriched with additives and reused in the drawing process - reducing waste and supporting sustainability.

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.
Liquid Mixers
Mixing is a vital process in the production of a diverse range of products in a wide range of industries. Based on our extensive experience and technological know-how, GEA offers a variety of batch, continuous and in-house custom designed mixing solutions for unique applications that meet specific customer needs.
