Our Eccentric Screw Pump at a glance

Standard equipment 

  • Offset drive motor with high operational factor for continuous operation
  • Low-maintenance thanks to double bearings and oil bath lubrication
  • Drive via stable flange joints and additional rubber joint protection
  • Sealing with dual low-maintenance slide ring sealing on pump chamber
  • Steel pump housing with single-sided connection flange DN 150 PN 16
  • Steel outflow flange with connection flange DN 150 PN 16
  • Wear-resistant rotor made of specially hardened Cr-Mo-steel

  • On request, it can be mounted on a galvanized console or a stainless steel console
  • Pumping manure
  • Pumping biomass or digestate in biogas systems
  • Pumping sewage sludge in wastewater treatment plants
  • Pumping industrial wastewater in industrial systems


  • Top performance under the toughest conditions (application in slurry and biogas plants)
  • Pumps media with high DM content
  • Low energy consumption
  • Space-saving design

"The HEX from Stallkamp sucks much better than comparable solutions with a rotary lobe pump and at a significantly lower power consumption. The eccentric screw pump also pumps high DM content media (up to 10-12 %). This can\'t be achieved with conventional rotary lobe pumps (max. 9 % DM content). Despite the strong performance, the pump runs quietly. We are very satisfied."

Testimonial R. Lamping
Lamping Biogas GmbH & Co. KG (pilot customer)

The flow rate (volume flow rate in m3) is dependent on the density and viscosity of the liquid, the type and the DM content of the manure (animal feed), the support height and distance as well as the diameter of the pipeline.
