Customer Testimonials


“We are extremely happy with the operation of the PFlow lift, and we have been running it with absolutely no problems. We will soon be moving from manufacturing six models to eleven, so it could not have been a better choice for a capital expenditure!”

– Roy Whitaker, Senior Process Engineer, Sea Ray in Palm Coast


“PWD does a lot of work with PFlow on more complex lifts. There are a handful of companies that can do the simpler, low payload, two level lifts. For anything where some real engineering expertise is required the list shrinks considerably. Goree brought us in specifically due to the challenge of designing and installing these lifts.”

– David Willemssen, Precision Warehouse Design
