Product Description

The Wangen BIO-MIX Pump

The Wangen BIO-MIX Pump can address your needs for conveying substrate, feeding in solid material, or loading the separators in the rigorous operation of your biogas plant.

WANGEN BIO-MIX pumps have been integrated for many years in the energy production process and undergone continuous further development and optimization. They are suitable for conveying maize silage, grass silage, GPS, solid manure, poultry dung, waste and co-ferments, which are mixed with liquid in the pump.

 

Conveying Substrate

Pumps in biogas plants have to convey viscous substrate between the fermenters. We offer different types of pumps according to the substrate to be conveyed and the biogas plant in question. Our years-long experience enables us to develop practice-related solution concepts.

WANGEN pumps have robust designs because substrates are often highly viscous and have to be pumped over long distances. Supplemented with dry running protection, pressure gauges or flow meters, they  display excellent performance even in automatic continuous duty.

 

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.

 

Loading the Separators

WANGEN pumps perform special tasks in biogas plants such as loading the separators for separating solid and liquid phases.

Conveying the substrates with their mostly high dry substance contents (DS) requires sophisticated pump technology. Optimum pumping results are guaranteed by the flow-optimized suction housing and a constant joint diameter which prevents the plating of long fibers.
