Actuator seals and cylinder wear particles contaminate hydraulic oil. Clean hydraulic oil ensures the durable operation of extrusion presses and other hydraulic machinery for extended time periods.

As long as the hydraulic oil remains clean, the operation can run according to the plan. Yet, when particles and water contaminate the hydraulic fluid, its properties deteriorate fast. This contamination causes costly production downtime due to the failure of pumps and other equipment.

Modern hydraulic systems require the use of high grade, clean hydraulic oil to maximize equipment utilization. This level of cleanliness is assured by a disc-stack centrifuge with 8,000 g-forces.

The image above shows small hydraulic oil centrifuge systems with built on pre-heaters. This system is ideal for servicing individual hydraulic fluid sumps in the aluminum extrusion or steel scrapping industry.


A hydraulic oil centrifuge separates water and fine solids from hydraulic oil on a continuous basis. The centrifuge bowl rotates at 7,800 RPM generating 7,000 Gs of force. This centrifugal force is enough to separate particles down to 0.5-micron level as well as all free water.
