The new BLUEline AN Rotary Lobe Pump

The new generation of rotary lobe pumps

We made it even better. The new BLUEline AN rotary lobe pump  stands for almost pulsation-free pumping, long service life and highest energy efficiency. The AN pump is available in two sizes with flow rates of between 0.03 and 35 m³/h. It replaces the AL series.
