What does one do with a pump that has 600 hp (447 kW) and pressures to 40,000 psi? Why, whatever one wants. The 605 Series diesel water jetting units are the 800 pound gorillas of the water blasting world. With power and flexibility to spare, if your application can’t be tackled by one of these units, it can’t be tackled at all. Models are available ranging in horsepower from 475 to 600 hp (354-447 kW) and with pressure from 4,000 to 40,000 psi (275-2,800 bar).
These diesel water jetting units are all built around the 605 convertible pump. This pump, with its quick-change, in-line fluid end design, has fewer parts for increased operating efficiency and simpler maintenance. And, it requires only a simple conversion kit to operate at pressures between 4,000 and 40,000 psi (275 and 2,800 bar).
The NLB 605 Series units are built to the exacting standards that have made NLB equipment the contractor’s choice for over 50 years. All operating controls, including the pressure-compensating by-pass valve and pressure gauge with snubber, are mounted on a separate accessory manifold, which provides additional protection for these important components.
