NLB Corp. extended the operating pressure range of its convertible 325 Series water jet pump units to 40,000 psi, creating what the maker says is the industry's widest operating pressure range available with up to 400 horsepower. Units can be converted in just 30 minutes to operate at 8,000, 10,000, 12,000, 15,000, 20,000, 24,000, or 40,000 psi. Current users of NLB's 325 Series plunger pump can add ultra-high pressure (UHP) capability with a simple kit. The 325 Series is available in 14 configurations with flows from 12 to 74 gallons per minute and diesel engines of 365 or 400 horsepower. All are trailer-mounted, with four-wheel electric brakes and a DOT lighting package.
