In 1947 we began to build and sell peristaltic pumps out of Houston, Texas. Since 1974 our pump and tubing operation have been located in Manchaca, Texas. As one of the oldest manufacturers of peristaltic pumps, Randolph has maintained a loyal following by delivering `rugged, reliable and simple to use` peristaltic pumps. We machine all the components of our pumps to our exacting specifications and extrude our own tubing. Our ability to control every facet of the manufacturing process continues to ensure prompt delivery of a quality product. The Randolph pump can be found working in industries such as printing, food, pharmaceutical, nuclear, and wastewater.
