Since 1977, PFlow has been devoted to the design and manufacture of safe and reliable vertical material handling equipment. We were instrumental in creating the vertical conveyor market and have led the industry from the start.

We’ve developed a leadership culture that provides a superior level of experience, engineering innovation, and customer support. From simple, two-level VRCs to multi-level, multi-directional automated lifting systems, PFlow will provide a solution.

"Before we could build a business, we had to create an industry".
