Interview technical manager SDI (Sludge Drying Plant) Tinus Hopman regarding the operation of DEX QM HYDRAULIC 32T 


In December 2019, I was made aware by our oil analyst Peter de Caluwé of ORM Advies of the existence of Dex Oil bv, which might be able to solve a problem we were having with the water separating capacity of the oils we use in the so-called sludge pumps (Intake 30 m2 per hour).

Having satisfied myself sufficiently that the Dex professionals could be classified as such, I decided to test with the recommended oil. Because it is a much thinner oil than prescribed, I asked for advice from our maintenance advisor Hydrauvision, just to be sure. This initially opposed a test with this thin oil, but after talking to Dex Oil's engineers, it dropped its objections, which turns out to have been a correct decision.

Because the pump system's load changes its composition quite often, we allowed the comparative test with the second pump system to last 6 weeks, eliminating the load differences.
The final oil analysis showed, that the DEX QM oil was very clean and contained almost no water (9 ppm), while the oil in the second pump contained 106 ppm of water. It also showed, that the DEX QM oil was more filterable according to the ISO 4406 count than the other oil. In particular, the relatively larger particles are filtered out of the oil more with the Dex Hydraulic 32T (ISO VG 32), and since larger particles mean more wear, it is expected that less wear will occur. The extent to which this will be the case can only be determined over a longer period of time.

From the mere fact, that a much thinner oil is used, it may be inferred, that less energy is used. Based on the results achieved, we decided to also equip the second pumping station with the Dex Hydraulic 32T. Based on these results and previously published results regarding the DEX QM oils, the operator of the wastewater treatment plant has decided to carry out a test with the DEX QM GEAR 100 using the so-called aerators. The publication of an interview with him regarding the results of that test may also be expected in due course.

Based on the results achieved here, I can advise all my colleagues in the Netherlands to talk to Dex Oil bv about solutions to oil-related problems and energy savings.

Technical Manager HHNK
