325 Series Diesel Units

The 325 Series water blasting units are quintuplex versions of the 225 Series. What that means is that opposed to three plungers, these have five, allowing them to run at higher horsepower and produce higher flows. Because these units use the exact same fluid end components as the 225 Series, they are a perfect next step when higher horsepower is needed. Models are available ranging in horsepower from 365 to 450 hp (272-336 kW) and with pressure from 8,000 to 40,000 psi (550-2,800 bar).

These units are all built around the 325 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 8,000 and 40,000 psi (550 and 2,800 bar).

The NLB 325 Series units are built to the exacting standards that have made NLB equipment the contractors choice for over 50 years. These trailer mounted units come 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.
