The Meyer Screw Pump is an ideal replacement for rotary airlock feeders that have prematurely failed when handling fine abrasive materials. The pump utilizes the material to be conveyed to form a seal during operation. An integral flap gate prevents blowback when introducing material into the system on start-up or when running empty. The unique hard coated screw design provides a continuous flow of material into the conveying air stream. Furthermore, this low-profile, dust-free dry pump significantly reduces abrasive wear, thus minimizing maintenance and the burden of costly downtime, notes the manufacturer.
