NLB Corp. has extended the operating pressure range of its convertible NLB 325 Series water jet pump units to 40,000 psi — providing what the company calls the "industry’s widest operating pressure range available with up to 400 hp." These units can be converted in just 30 minutes to operate at 8,000 psi, 10,000 psi, 12,000 psi, 15,000 psi, 20,000 psi, 24,000 psi, or 40,000 psi. Users do not have to buy a new unit; ultra-high-pressure capability can be added with a simple kit. The NLB 325 Series is available in 14 configurations to suit users’ needs, with flows from 12 gpm to 74 gpm and heavy-duty diesel engines of 365 hp or 400 hp (272 to 298 kW). All are trailer-mounted for portability, with 4-wheel electric brakes and a DOT lighting package. (
