Vacuum system with dry well pump

With a dry-installed pump in a PE pump well from Landia, you get extra speed when sluicing slurry.

This is how a vacuum system with a dry-installed pump works

In barns with vacuum systems, the slurry is released when plugs are lifted in the barn. The slurry flows directly into the pump, which is installed at the bottom of a buried PE pump well. The pump in the well is started as needed. When the pump is running, a negative pressure is formed in the main pipe under the troughs in the barn. 
The slurry that is in the pipe and the sumps is sucked out and pumped on to the storage tank. By choosing a solution with automatic stop, unnecessary wear is avoided while saving time. If the slurry is to be pumped far or through an increase in terrain upslope, then using a high-pressure pump in the dry well may be a favourable solution.
The pre-cast pump well in PE is used instead of a reception tank. It can also be used as a well for increasing pressure when pumping slurry over long distances and/or through an increase in terrain upslope. The well can be supplied in several sizes ready for use with the desired pump and suitable damper, pipe socket and lid. The pre-cast PE pump well is completely sealed and fitted with valves at inlet and outlet, lid, vent and bottom plate so that it stays in the ground in case of a rise in groundwater.


• Increases the vacuum effect, faster sluicing, which means that the entire basin is emptied.
• PE pump well instead of a reception tank reduces odour nuisances.
• Comes as plug and play and just needs to be connected to the inlet and outlet pipes.
• Protected against a rise in groundwater so that the pump does not drown.
• The pump is easy to service in a PE pump well.
