Vacuum Railcar Unloading

Vacuum Railcar Unloading
Bulk Conveying Systems

The VRU is a reliable, low cost and simple solution for your railcar unloading requirements.

Its reliability is based on simplicity.  The VRU uses a vacuum pump to convey material to a silo-mounted receiver.  A timed valve on the pump then reverses the air flow to "power load" the receiver and backwash all filters in the system without stopping the pump.  Operation is completely automatic, highly efficient and fast.

  • Reliable, efficient operation
  • Low cost, versatile
  • Simple to operate, easy to maintain
