Product Description

The Wangen Type A Pump

The Wangen Type KL-R Pump can address your needs for feeding in solid material in the rigorous operation of a biogas plant.

Feeding in solid material

With WANGEN BIO-MIX pumps, solid materials are conveyed into the pump via the jaw hopper and mixed there with liquid from fermenters, after-fermenters or liquid manure tanks. Only then is the mix transferred to the fermenter.

The advantages of feeding in liquid with WANGEN BIO-MIX pumps:

  • Good mixing in of the solid materials (less stirring required in the fermenter)
  • Troublefree conveyance over large distances and great differences in height (e.g. when extending biogas plants)
  • Several fermenters can be loaded with one feeding system
  • Optimum mixing in of even difficult solid materials, e.g. grass silage and solid manure.

WANGEN BIO-MIX pumps prove that we combine experience with a readiness to create application-specific production innovations. Our aim is the trouble-free operation of biogas plants.
