The Meyer pneumatic screw pump is a heavy duty dry materials injection pump designed to feed dry pulverized material into a pneumatic conveying line. According to Meyer, the pump can handle highly abrasive, friable or very fine powders that wear out other dilute phase feeders. Unlike rotary airlocks that require tight clearances to seal against conveying air, the pump uses the materials to form the seal. An integrated gate prevents blowback, and the pump can handle temperatures up to 450° F.
