Rolling, cutting & grinding oil

Benefits of our centrifuges

• Extend oil service life and oil change intervals

• Remove water and solid contaminants continuously

• Improve machine reliability and availability

• Reduce wear on bearings, pumps and critical components

• Improve process stability and product quality

• Reduce oil consumption and disposal costs

• Minimize maintenance requirements and downtime

• Compact design for easy integration into existing systems

Why metalworking oils need continuous treatment

Rolling, cutting and grinding oils are continuously exposed to contamination during operation. Water ingress, metal fines, dirt particles and process residues can accumulate in the circulation system and negatively affect lubrication performance.

If not removed, these contaminants may lead to:

• Increased equipment wear

• Corrosion of critical components

• Reduced product quality

• Increased maintenance requirements

• Unplanned production interruptions

Reliable oil treatment is therefore essential to maintain efficient and stable production.

Continuous oil purification with GEA separators

GEA centrifugal separators are designed for the continuous purification of rolling, cutting and grinding oils. Installed in a bypass loop, they continuously remove water, metal particles and other contaminants while production remains in operation.

The efficient separation process helps maintain oil quality, protects equipment and ensures consistent process performance. Compared with conventional settling systems, centrifugal separation delivers faster and more reliable contaminant removal while reducing maintenance effort.
