IQ-Series Rotary Lobe Pump

The next generation rotary lobe pump.

The latest Vogelsang innovation in Rotary Lobe Pumps is here! Utilizing our exclusive HiFlo lobe design, IQ series pumps have been specifically designed to reduce the number of spare parts, and maintenance time compared to other lobe pumps. The ability to pump highly viscous liquids, pulsation-free combined with unmatched design flexibility, makes IQ the next revolution of pumping technology.

The IQ does everything that our industry leading VX design will but has a one-piece housing that is incredibly easy to work on. The all new IQ design works well in applications requiring a positive displacement pump up to 343gpm. All Vogelsang pumps can run dry without damage, self prime and run in forward or reverse. Vogelsang pumps are great for suction lift applications up to 25'. The IQ features our standard 4 wing HiFlo Lobe design, the pump delivers pulsation free pumping action making it ideal for many applications.What makes the IQ a great advance in pump design is the simplified wet-end. We've eliminated 50% of the spare parts compared to traditional rotary lobe pumps. This translates into real savings when looking at overall operational costs.

Easy to Install

Standard flanges can be rotated into a variety of configurations. This enables the IQ series pumps quickly and easily in different positions on or built without requiring special connectors. Flanges are available for a front and back facing configuration as well.


The pump housing is a complete component. To access the wet end, remove eight bolts and slide off the cover. The entire wet end is easily accessed for routine maintenance.
