PMM initially targeted the wood products industry with high quality feeders and screw conveyors.

With the introduction of the modular PMV® rotary valve, the company expanded its reach into the co-generation, mining, cement, chemical and pharmaceutical industries, among others.

PMM’s products are designed to convey virtually any dry, granular or powdery material. Our tight tolerances and high quality materials and finishes are ideal for abrasive substances such as fly ash, coal, coke, volcanic cinders, diatomaceous earth and pebble lime.

PMM also manufacturers feeders and parts for the blower truck industry, and offers custom machining and fabrication services, utilizing the latest CNC and robotic equipment.
