Working Principle

The GN Solids Vacuum Pump operates by using compressed air to create a high vacuum inside the pump tank. The vacuum draws in material through the suction line. After a few seconds, the pump switches the direction of the compressed air to create positive pressure, which pushes the material out through the discharge line. This process is highly efficient and can be performed either manually or automatically, depending on the model.
