Tank (VDT) Pump System

SHARE

The Vacuum Pressure Tank is an innovative pump system, specially developed for pumping thick slurry-like products for biogas installations. The feeding of the digesters should not be interrupted due to malfunctions and maintenance, as this almost immediately means lower biogas production and thus loss of turnover. The ingenious design of the Vacuum Pressure Tank ensures that pumping problems are a thing of the past. Jamming of pumps, only being able to pump liquids with relatively little dry matter, frequent replacement of parts: all a thing of the past with the Vacuum Pressure Tank developed by Biogas Plus.

Because the vacuum pump and the associated motor itself do not come into contact with the biomass, the pump system is hardly susceptible to failure and is virtually maintenance-free. 

Depending on the mixture, it is possible to pump slurry of 25-30% dry matter without problems. More dry matter usually means more energy and more efficient fermentation. 

Advantages of a Vacuum Pressure Tank are:
  • Pumping slurry with high% ds 
  • Very high capacity
  • Hardly susceptible to failure
  • Virtually maintenance free
  • Low energy consumption
  • Easy dosing fermenter
  • Low pressure in the pipe 
  • Long lifespan
The Vacuum Pressure Tank is vacuumed so that the tank fills with biomass. The tank is then pressurized and the biomass is pressed away to the relevant tank / silo. An additional advantage of the principle of the Vacuum Pressure Tank is that the same pipe is used for pressing as for vacuuming. This saves a lot of valuable pipework and increases your flexibility.  

With the Vacuum Pressure Tank you can also dose much more accurately than with traditional pumps.
