For these reasons, it is vital to check the bearing oil regu- larly for the particulates and replace the oil as necessary. All ViscoTwin pumps come standard with two magnetic plugs to help collect and trap particulates, keeping the oil cleaner for longer. PROCESSTEC INC. 2024 Page 115...

As the bearings change temperature, they both expand and experience thermal shock, both of which ser- ve to increase bearing wear and tear. With the rise in operating temperature, the oil also begins to thin, providing less lubrication for the bearings. PROCESSTEC INC. 2024 Page 117...

GET TOMORROW´S TECHNOLOGY TODAY Oil Thickness High viscosity oils are more effective at lubricating bearings. They reduce friction between the balls and the outer casing, thus reducing both heat generation and damage caused by parts contacting. Page 118 PROCESSTEC INC. 2024...

RPM’s over the same time. Furthermore, the RPM’s limits the effectiveness of more viscous oils due to the increased resistance from moving through thick oil, outweighing the benefits of more viscous oil. PROCESSTEC INC. 2024 Page 119...
