Eaton Diesel engine EGR pump

The TVS EGR pump is driven by a 48-volt electric motor, making it completely independent from engine speed and significantly more controllable than pump-less EGR systems. TVS technology enables EGR flow in operating regions where it wasnÕt possible to drive flow before and provides more accurate EGR flow rate control for better combustion and emissions management.Ê

The TVS EGR pump leverages our experience with superchargers and positive displacement pumps. While the two are similar, a supercharger generates a high boost with average pressure ratios of 2.0 to 3.0 for many applications; an EGR pump uses a shorter rotor assembly and lower twist to produce flow just slightly above the intake pressure, or a pressure ratio of 1.05 to 1.50.
