Pumps inside modern internal combustion engines must handle oils with extremely low viscosity due to the emission reduction needs. Saint-Gobain Seals’ Meldin® gerotors are made of high-temperature polymers and minimized tolerances, which are a perfect fit for demanding applications with a high level of lubrication needs.
An example of this can be seen in motorsports where our Meldin® 5330 gerotors are used in oil and scavaging pumps on Formula 1 racing vehicles and MotoGP motorbikes. In this type of motorsport application, typical working conditions include temperature level of around 150°C, low pressure (a few bar) but high speed (20,000 RPM or more). Lubrication is provided through oil and the counter surface is aluminium.
