Are you having problems achieving maximum material rates due to worn airlocks? The Meyer Screw Pump is an ideal replacement for rotary airlock feeders that have prematurely failed when handling fine abrasive materials. Meyer’s Screw 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, this low profile, dust free dry pump significantly reduces abrasive wear, thus minimizing maintenance and the burden of costly downtime.  With a variety of standard construction options already built in, this rugged, high performance dry material injection pump will exceed all your previous airlock feeder expectations.
