NLB’s line of water jetting units are built around the innovative model 225 convertible pump. This pump, with its quick-change, in-line fluid end design, has fewer parts for increased operating efficiency and simpler maintenance. The durable and easy-to-service fluid end accepts conversion kits (sold separately) that allow the pump to operate at pressures between 8,000 psi and 40,000 psi (552 to 2,800 bar).

The NLB 225 Series units are built using the same rugged, reliable designs that have been field proven for over 40 years. The trailer mounted unit comes standard with features like four wheel electronic brakes, full D.O.T. lighting package, and heavy-duty axles. 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.

NLB’s Quick Change Fluid Ends.

  • The quick conversion fluid end allows the pump the capability to operate at pressures between 8,000 psi (552 bar) and 40,000 psi (2,800 bar) and makes maintenance fast and easy.
  • Conversion takes only about 20 minutes (30 minutes for 40,000 psi) using NLB’s Quick Change Conversion Kit (sold separately).
