Features and Benefits of Meyer Pneumatic Screw Pumps

The Meyer Pneumatic Screw Pump is an airlock designed to feed dry pulverized material from a gravity feed hopper into a pneumatic conveying line by using a screw auger. It is engineered to perform in applications that exceed the abilities of typical dilute phase rotary feeders. It is an ideal replacement for airlock feeders that have failed to handle fine, abrasive or friable materials.

Unlike rotary airlocks, which require tight clearances to seal against the conveying air, the Screw Pump utilizes the conveyed material to form a seal during operation and an integral flap gate prevents blowback during system startup or when running empty. Compared to double flap valves, which batch material as the gates cycle open and closed, the Screw Pump provides a continuous flow of material into the conveying air stream. It is a dust free feeder and significantly reduces abrasive wear; minimizing maintenance and unplanned, costly downtime.
