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. With many standard models available for quick delivery, we also provide custom solutions to various applications.

Year Founded:

Randolph Austin Company, Extrusion Division

Randolph Austin Company began manufacturing flexible plastic tubing in 1981. One of our manufacturing applications required very precise and close tolerance tubing which was not readily available. At that time the only way we were able to accomplish this was to start our own manufacturing facility for precision flexible tubing. Over the years we have developed several types of tubing to compliment the transferring of different solvents, acids, slurries, inks and food products. With much testing and development we now manufacture five different lines of tubing for various fluid compatibility. Cilran, ED- Plex, Prothane II, Povinal, and Vytex.

In addition to our flexible tubing lines, in 1989 we developed a water soluble plastic material that is now used for packaging of foaming agents used in increasing gas well production. It is also used as a carrier for biocides and other applications requiring water soluble packaging.

In the early nineties we began work on a urethane soft enough to work in peristaltic pumps. Prothane II was developed for applications requiring demanding flex life and durability. It is now one of our most popular and one of the softest and most durable urethane tubing on the market. This is used in many areas such as transferring of slurries, inks and some solvents. We also manufacture a food grade vinyl tubing as well as a solvent resistant tubing used for transferring aromatic hydrocarbons such as toluene and xylene.

In addition to our extruded tubing lines Randolph Austin Company is a diverse company that is associated with the following companies:

In addition to our pumps and tubing, Randolph Austin offers capabilities in gear fabrication, custom machining, water-soluble polymers, and custom extrusion. Our rubber molding and compounding facilities have recently moved to CPI in Kyle, Texas.
