The Ring-O-Matic 550 Dual Pump Combination Sewer Line Jetter and Vacuum Excavator gives contractors and municipalities the advantages of a dedicated, combination jetter/vacuum truck in the more versatile footprint of a compact trailer unit.

Compared to PTO-driven, truck-mounted models, the Ring-O-Matic 550’s low initial investment cost and lower operational costs have made owning a combination jetter/vacuum machine affordable even for those who do not need jetting and/or vacuum excavation services on a daily basis.

The Ring-O-Matic 550 fits into spaces too confined for truck-mounted combo rigs, yet it can clean sewer lines up to 20 inches in diameter. Its versatility makes it a practical alternative for numerous other applications, as well, such as potholing and lateral cleaning.

Powered by an 81 hp CAT turbo diesel, the Ring-O-Matic 550 machine features a 1,000 cfm blower and can deliver 27 gpm at 2,700 psi up to 400 feet with its 3/4-inch jetter hose. The trailer’s axles are rated to 16,000 pounds, allowing the 550-gallon spoils tank and 500-gallon freshwater tank to be easily pulled behind a suitably equipped 3/4- or 1-ton truck.

Bob Zylstra, Ring-O-Matic’s engineering director, says the unit’s compact size makes it particularly attractive not only to smaller municipalities but also to larger cities looking for a utility combo jetter to complement their truck-mounted units. “Its low profile offers a 2- to 3-foot height advantage over truck-mounted units. It’s less than half their weight and it’s narrower. This makes it easier to use in tight alleyways with overhead obstructions, with less potential for damage to soft asphalt or brittle cement pavements.”

In addition to its versatility, Ring-O-Matic CEO Brian Metcalf believes the trailer-mounted Ring-O-Matic’s price-point has now offered the advantages of jetting to customers who could not previously justify purchasing jet-vac equipment. “Customers will quickly learn that although they acquired their Ring-O-Matic 550 with one purpose in mind, they’ll see many other applications they can use it for.”

Should customers have questions or need assistance of any kind, Metcalf says Ring-O-Matic has ideal logistics for industry-leading responsiveness. “Although we have a global presence in the industry, our modest company size and our ideally located headquarters in Pella, Iowa, enable us to provide close customer support to every region of the U.S.”
