The Model 355 trailer-mounted, high-pressure waterjet pump unit from NLB Corp. is powered by a continuous duty 350 hp six-cylinder Tier 4F diesel engine and features a quick-change, in-line fluid end design, slow-running, reciprocating plunger pump. 

The pump is rated for a maximum operating pressure of 20,000 psi and can be converted to operate at 8,000, 10,000 or 15,000 psi. Flows range from 26 gpm to 63 gpm. 

“At 10,000 psi, this pump will put out 51.5 gpm,” says Jim Van Dam, director of product development and marketing, NLB Corp. “The highest horsepower prior to this was 300 hp that put out 44 gpm. This gives you more flexibility to run multiple operations.” 

Applications include tube and pipe cleaning, product removal, surface preparation, tank cleaning, tube bundle cleaning, pavement marking and rubber removal, concrete hydrodemolition, and concrete and pipe cutting. 

“The components have been redesigned to accommodate the higher horsepower, but anybody who has worked on an NLB convertible pump will recognize them very quickly,” he says. “The pump’s maintenance and operation is consistent with other NLB systems. It’s not going to be a new experience for operators.” 

The latest model in the NLB 225 Series, the pump unit has a 100-gallon aluminum fuel tank, 12-volt electric start, inlet water filter, oil-filled pressure gauge with snubber, accessory manifold with bypass valve and water pressure actuated throttle control. 

The pump is available in an UltraGreen configuration for compliance with the latest Tier 4F emission requirements. Compliance with Tier 4F standards is required by the California Air Resources Board (CARB) and written into bid specifications and site permits for DOT and public works projects in various states, including New Jersey, Pennsylvania and Massachusetts. 

In addition, many large, publicly owned companies are making environmental goals key elements of their business strategies. Dow Chemical and 3M, for example, require that all diesel-powered equipment brought into their facilities be Tier 4F certified. 

“Tier 4 Final UltraGreen units are more fuel efficient,” Van Dam says. “We are doing everything we can to get as much horsepower out of as little fuel as possible while not affecting end performance to minimize emissions.”

The heavy-duty tandem-axle trailer is 90 inches wide, 185 inches long and about 81 inches high. It weighs 9,000 pounds and includes 16.5-inch wheels, DOT lighting package, electric brakes and industrial grade enamel finish. 248/624-5555; www.nlbcorp.com.
