To validate new processes for commercial systems, the processes are first tested in pilot systems. Often the delivery rates are low, ranging between 0.5 to 8 m³/h, and cannot be realised with a reactor pump. For this reason, Egger has developed a pilot pump S that meets all requirements for commercial process pumps. This series has been designed for boundary conditions of 25vol% gas fraction, 100 bar system pressure and a temperature of 280°C.
