ROTARY LOBE PUMP FOR HIGHEST EFFICIENCIES High efficiency even with demanding media One-piece housing with low dead space Compliance with industry-specific standards through new sealing options ATEX and TA-Luft compliant 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 ALL-ROUND PUMP WITH HIGH EFFICIENCY Applications for VY rotary lobe pumps The VY rotary lobe pumps are based on Vogelsang’s proven VX series. Different seals can also be variably used in the new housing – depending on industry-specific standards and requirements. This makes the VY series an all-rounder for use in, for example, the chemical industry as well as in the paper and textile sectors.
