US Jetting RPD Run-Dry Pumps
RPD - Radial Piston Diaphragm
US Jetting designs and manufactures a Radial Piston Diaphragm (RPD) Pump. This pump design, first introduced into the US market by Nick Woodhead, founder of US Jetting, LLC revolutionized the high pressure jetting industry. Originating the concept of "High Pressure - Low Flow", these pumps allowed sewer & drain cleaning contractors the ability to clean a broader range of pipe diameters with a single unit. Utilizing half-inch diameter lightweight high pressure jetting hose, pipe cleaning versatility dramatically changed, allowing for residential, commercial, industrial and municipal sewer lines to be cleaned with a single unit.
US Jetting RPD 8-Cylinder Pump & Major Components
The RPD design set the standard for the sewer & drain cleaning industry. Using less water at the mucher high water pressure of 4,000 PSI easily removed grease, roots and debris from pipes. Compact in design and requiring less water storage, these units proved their worth where larger flusher type units were once partially employed.
First designed to provide high pressure water for the offshore oil industry by utilizing saltwater, RPD pumps became infamous for reliable long term use at 4,000 PSI without pressure loss or the need for seal replacement to maintain pressure. Although since superceded in design & efficiency by US Jetting Run-Dry Plunger Pumps, RPD pumps maintain a key advantage of using saltwater or brackish water still critical for applications in the offshore oil industry and within shipyards.
RPD pumps could reliably produce 4,000 PSI that that other piston plunger pumps could not match until the development of the US Jetting series of Run-Dry Plunger Pumps. With the development of the proprietary US Jetting Run-Dry fluid end, greater flow capacity could be achieved on a less complex plunger pump frame. The US Jetting 4018 Run-Dry pump now produces the near maximum pressurized water flow capable of passing through a half-inch diameter hose for a more efficient unit. Less moving parts and a simple design allow for reduced maintenance time and costs.

Many early sewer & drain cleaning RPD users still prefer RPD pumps, ordering new RPD equipped units as replacements or additions to their inventory. US Jetting still manufactures RPD pumps, maintains a full inventory of spare parts, provides service and promotes their specialized use.

US Jetting reallies the advantage of Run Dry pumps - the ability to run out of water while under the strain of high pressure jetting without causing pump failure or expensive repair damage. High durability with reduced maintenance (and associated costs) result in US Jetting High Pressure Jetting units being more productive and profitable to operate that no other competitor can match.
