Vogelsang IQ Series Rotary Lobe Pumps


The innovative design of the rotary lobe pumps in the IQ series is Vogelsang's answer to the all too familiar demand in the wastewater sector: "Cut costs and increase efficiency". Whether used as a sludge pump in a sewage treatment plant, as a wastewater pump in the sewer system or on tankers or disposal vehicles, Vogelsang rotary lobe pumps from the IQ series can be adapted to common installation scenarios quickly and easily thanks to their variable connector parts.

The integrated InjectionSystem makes the rotary lobe pumps resistant to foreign matter in the wastewater and, together with the built-in dry running protection, ensures high suction capability. As with all rotary lobe pumps, the flow direction of the IQ series can be reversed by simply changing the direction of rotation. It doesn't matter if they're used as a wastewater pump or as a sludge pump, the pumps in this series reliably draw fluids from the deepest of shafts. Given their high efficiency, they not only convey wastewater, but also abrasive primary sludge or highly viscous, thickened sludge, for example. The HiFlo® lobes invented by Vogelsang make pulsation-free and low-vibration pumping possible here.

What makes these pumps unique is their maintainability. Upon removing the pump cover, all wear parts, which have been significantly reduced in number, are optimally accessible and can be replaced by the user in just a few simple steps. This means that the space required for servicing and maintenance work is next to nothing, which is a real advantage for the user when space is tight, as is the case with shafts or mobile pump units.


  • The easiest maintenance, rapid onsite service
  • Quick, optimum access to the pumping elements
  • Self-priming and resistant to dry running
