The 125 Series high-pressure waterjetting system from NLB Corp. features 125 hp and 145 hp models that can be configured in about 20 minutes to operate at any of eight pressures, from 6,000 to 40,000 psi, with the optional conversion kit. Comparable flows range from 4.4 to 29 gpm for the 125 hp model or 4.8 to 32.5 gpm for the 145 hp model. Both models are powered by either a Cat C4.4 or QSB 4.5 Cummins continuous-duty, six-cylinder diesel engine.

"The conversion kit gives contractors the option of having one pump in their fleet that can go from tube cleaning at 10,000 psi at 17 gpm on Monday to paint removal on Tuesday (at 40,000 psi and 4 gpm)," says Jim Van Dam, marketing communications manager for NLB. Unit output is determined by the size of plunger in the positive displacement reciprocating pump.

"It's a balancing act," Van Dam says. "You can't run at 40,000 psi with the same set of plungers you use at 10,000 psi because the forces on the power end of the pump would be too great and it would fail. You're trading off the amount of water for higher pressure. Essentially, the conversion kit is a different sized plunger that's installed into the pump."

The 125 Series is available in models that deliver 29, 22 or 17.5 gpm at 6,000, 8,000 and 10,000 psi or 12, 9, 7.5 and 4.4 gpm at 15,000, 20,000, 24,000 and 40,000 psi. The 145 Series is available in models that deliver 32.5, 24.5 and 19.5 gpm at 6,000, 8,000 and 10,000 psi or 13, 10, 8 and 4.8 gpm at 15,000, 20,000, 24,000 and 40,000 psi.

The trailer-mounted unit comes standard with four-wheel electronic brakes, full DOT lighting package and heavy-duty axles. The tandem-axle trailer has 14-inch tires and measures 80 inches wide, 164 inches long, approximately 90 inches high and weighs 5,500 pounds.

Other features include water-pressure actuated throttle control that monitors operator demand and adjusts output, heavy-duty V-belt engine-driven pump assembly, 80-gallon fuel tank, 12-volt electric start, inlet water filter and 30,000-pound oil-filled pressure gauge with snubber. All operating controls, including the pressure compensating bypass valve and pressure gauge with snubber, are mounted on a separate accessory manifold for extra protection. 800/441-5059; www.nlbcorp.com.
