Biogas pumps with greater cost-effectiveness thanks to reduced maintenance and servicing
Rotary lobe pumps of the IQ series for biogas applications

A significant advantage brought to many biogas plants by Vogelsang's rotary lobe pumps has been perfected even further in the pumps in the IQ series: As a result of their unique design, they can be installed with no hassle, are easy to handle and, most importantly, they can be serviced or repaired quickly and simply on site.

With their variable connector parts, the rotary lobe pumps in the IQ series can be easily adapted to common installation scenarios. Equipped with an integrated fluid buffer and the InjectionSystem as standard, they boast optimal suction characteristics and are ideal for drawing liquid manure and recirculated material, among other things, from deep sumps, even if this contains foreign matter like stones. The pump chamber consists of one central part, which can be dismounted in a few easy steps. This allows access to the pumping elements for servicing and maintenance work while the pump itself remains securely screwed into the pipe of the biogas plant. At the same time, the number of spare parts in the rotary lobe pumps of the IQ series has been halved, for a significant reduction in both the cost and the time required to replace wear parts.

The computer-optimized housing shape and the resulting high level of efficiency combined with the pulsation-free HiFlo® lobes bring about economical and low-vibration pumping at biogas plants.

Features of the IQ series

Quality cartridge: The mechanical seal for pumps by Vogelsang
The Vogelsang Quality Cartridge stands for modern sealing technology. The mechanical seal in cartridge design is manufactured automatically in the factory, completely pre-assembled and checked by computer. This makes it quick and easy to change on site: assembly errors are avoided and the time required is reduced. This means quick and easy replacement of the shaft seal as well as safe commissioning after seal replacement.

Additional information:

Unlike conventional lobes, Vogelsang’s HiFlo® lobes ensure pulsation-free pumping and consequently longer lifetimes for the drive and coupling. At the same time, the suction capacity is increased due to the higher number of sealing lines. The improved internal sealing enables suction from deep pits.

Additional information:
Larger lobes and pump covers can be installed in the IQ series
without making any modifications; this can increase capacity by as
much as 40%.
With QuickService, Vogelsang’s rotary lobe pumps are very easy to maintain: The lobes, seal, and wear plates can be replaced on-site without dismounting the pump. This saves money and ensures the highest possible level of equipment availability. Long downtimes are cut to a minimum.

Options of the IQ series

Alongside the standard model in abrasion-resistant gray cast iron, versions in stainless steel are stocked as well. Other options for customization include heat treatment and wear-resistant coatings for the wear plates and housing components.
An ATEX-compliant version can be supplied for use in areas subject to explosion hazards.
