Conveying appliance for polymer flake-containing water

摘要

The device has an elastic hose (2) containing the medium to be conveyed, or a conveyor tube (1), to separate the medium from the pressure medium, and reduce wear and corrosion. The adaptable volume permits a pressure increase adapted to the medium to be conveyed. Free flow valves do no apply mechanical load to the flakes. Free flow intake and free flow pressure valves (11) are moved by a foreign energy, when pressure balance is present on both sides. The free flow valve profile remains fully open during a stroke, by controlling the valve plates (7).
