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. MAINTENANCE OF VOGELSANG ROTARY LOBE PUMPS How to disassemble a VX pump Open the cover: Unfasten four nuts, remove the cover and you have free access to the pumping chamber. If necessary, you can also replace the wear plate of the cover at this stage. Dismount the rotary lobes:
