Geroter pumps are a type of inside gear pump. They feature a rotating ring and gear and they are actually quite an efficient model of hydraulic pump. Because of the fine tolerances that are used in them, they are somewhat similar to an inside gear pump. These are a type of inside gear pumps, but there are also the crescent inside gear pumps that are made by some manufacturers.
Those ones are used based on personal preference. Because there are so many applications of pumps—either gear, vane or piston—these ones are efficient and they may be used in applications where there is a fixed displacement pump driven by a VFD or servo motor. You have variable inlet motor that controls the flow of the pump that is fixed. Those are one of the advantages I’ve seen used for a gerotor pump.
