Trochoidal gear pumps produce significant flow pulsations that result in pressure pulsations. which interact with the system where they are connected. shortening the life of both the pump and circuit components. The complicated aspects of the operation of a gerotor pump make computational fluid dynamics the proper tool for modelling and simulating its flow characteristics. https://www.roneverhart.com/Mackie-ProFX16v3-16-channel-Mixer-with-USB-and-Effects-p14934/
