NLB Corp. has introduced a semi-automated waterjet system that lets the operator safely work multiple accessories from a climate-controlled cab.

The Automated Remote Manipulator (ARM) allows operators to keep their distance from the waterjetting action by using joystick controls to position, start and stop the flow of high-pressure water (up to 40,000 psi, or 2,760 bar, at 600 hp), the company says.

NLB Corp.'s Automated Remote Manipulator (ARM) is a semi-automated waterjet system that lets the operator manipulate multiple accessories from a climate-controlled cab.

Specialized tooling is mounted on the arm of a mini excavator, allowing the machine to handle diverse applications such as shellside tube bundle cleaning and hydrodemolition, according to NLB Corp. There is a quick-connect system for changing accessories.

The system has a vertical reach of about 12 feet and a horizontal reach of about 17 feet, with a wide waterjet pattern, the company says.

Waterjet Nozzle

The company also recently introduced a new tube cleaning nozzle for ultra-high-pressure applications.

NLB Corp.'s new RPN4009 is a self-rotating waterjet nozzle for cleaning pipes and tubes at pressures up to 40,000 psi (2,760 bar).

NLB Corp. nozzles

The RPN4009 water jet nozzle is the newest addition to the Typhoon 10 series and can clean at pressures up to 40,000 psi, the company says.

The nozzle works at a maximum flow of 9 gpm (34 lpm) and rotates at 7,000 rpm. It is coated with titanium nitride and can be ordered with cutting/cleaning or polishing heads, the company says.

The nozzle is designed for a minimum pipe diameter of 0.75 inches and is the first nozzle in the Typhoon 10 series to operate ultra-high pressure, according to the company. The Typhoon 10 series includes four other waterjet nozzles for pressures from 15,000 psi to 24,000 psi (1,035 bar to 1,656 bar).
