Result
The viscosity state of PHI OIL Universus Gold 5W40 improves the pumpability, which prevents the manifestation of cavitation. Even though the oil change interval was increased to 15,000 operating hours, the pump life span would increase tenfold to 25,000 operating hours. The condition of the hydraulic oil is periodically analysed to determine usage, in order to determine the optimal time to change the oil.
Client testimonial
We had five straddle carriers in use and used 22(!) hydraulic pumps a year, even though we changed the entire 800 liters of hydraulic oil every 2,400 operating hours. Now we have 6 devices in use and use no more than a maximum of three pumps in a year. Instead of changing the oil, we now analyse the use of the oil every 2,400 operating hours to control the condition of the oil. The oil is in such good condition that it only has to be changed every sixth time. That means that instead of the previous six oil changes, we now do five oil use analyses and one oil change. In total the maintenance costs and the service costs of the straddle carriers through use of PHI OIL Universus Gold have been reduced from 80 euro to 52 euro per operating hour – i.e. 35%!
