How to expand the lifetime of your lab press

Are you driving your car for 10 years without changing the oil? In order to keep your vehicle in proper condition and to extend the engine life, good lubrication is needed regularly. 

So why do you never exchange the oil of your hydraulic lab press? We advise you to exchange the hydraulic oil every year. In this blog we explain how the lifetime of your lab press can easily be extended by changing its hydraulic oil.


Why change the hydraulic oil of your press

Hydraulic oil ages and even has an expiry date. It is a mineral and not a synthetic oil. The additives decrease in quality over time, especially when the press is not often used.


The oil types we use have a good thermal and chemical stability. They minimize sludge formation and provide excellent performance according to the industry-standard ASTM D 943 TOST test (Turbine Oil Stability Test), which ensures a reliable and clean system.

However, thanks to the fact that our laboratory platen presses are mainly used in laboratories with an ambient temperature of about 20°C, the oil is never used at the operating temperature of 60°C. The degree of moisture increases, which means that the compressibility increases and the risk of corrosion as well.


Additionally, the hydraulic oil that is inside a hydraulic tank is half of the oil that is used in the whole hydraulic system. The remaining half is stored in the hydraulic pump, the motor, the manifold, the hydraulic cylinder and the pipes and hoses.


So when oil is exchanged, not all the oil in the hydraulic system will be replaced but only the oil in the hydraulic tank. Old oil and new oil are mixed.

Since a full exchange is not possible and there is always residual oil left, we recommend never to mix two different brands or two different types of oil.

Oil is not expensive and exchanging oil every year extends the lifetime of your hydraulic lab press.
