Meyer & Sons pneumatic screw pump


Meyer & Sons offers a pneumatic screw pump. Meyer says its pump is an ideal replacement for rotary airlock feeders that handle fine or abrasive materials. The screw pump utilizes the material to be conveyed to form a seal during operation, with a flap gate that prevents blowback when introducing material into the system on start-up or running empty, according to the company. It has a hard coated screw design and dry material injection pump.
