THE GEARLESS ROTARY LOBE PUMP Up to 54 % less weight Up to 35 % less space Easier service Lower power consumption Incredibly quiet running THE ROTARY LOBE PUMP PRINCIPLE How Vogelsang rotary lobe pumps work The rotary lobe pump is a positive displacement pump. The pumping principle is based on two counter-rotating pumping elements, known as the rotary lobes. These are mounted on two synchronized shafts. The rotational movement of the lobes increases the volume of the pumping chamber on the suction side. This creates suction, which draws the medium into the rotary lobe pump. As the rotational movement continues, the medium is then enclosed in cavities between the rotary lobes and pump housing and it is issued on the discharge side by the pumping chambers as they reduce in size again; the rotary lobe pump conveys the medium directly. Due to their mirror-symmetrical design, rotary lobe pumps are independent of the direction of rotation and can pump in either direction without restriction. The HiFlo lobes developed in the 1990s operate pulsation-free, ensuring low-vibration and exceptionally gentle pumping. THE GEARLESS PUMP THAT IS MORE COMPACT AND LIGHTWEIGHT THAN EVER BEFORE Rotary lobe pump GL186 The GL 186 series is characterized by its sturdiness and power. As with the VX series, this gearless variant of the rotary lobe pump is just as powerful. The series is currently available in two different sizes. It is particular suitable for use in mobile applications where space is at a premium and a low unladen weight is required yet large quantities still have to be transported safely and reliably.
