Technology & Design Centered on Performance.
NLB StarJet ultra high-pressure water jetting stripe removal systems have held a position as the most durable, technology performance production leaders in the industry. The SRV-7 builds on that heritage by introducing a new center-component design that offers improved performance, less wear and reduced maintenance.
The key to this new design is the concept of balance. The slow-running, robust 325 Series pump, along with a Cummins (L9-430 T4F Stage V) 430 hp diesel engine are in centerline position on the chassis, resulting in a more even chassis weight distribution. Add that to the unique water/debris collection design that proportionately distributes fresh water and collected debris, and you eliminate uneven weight transfer from job start to finish.
The SRV-7 also features NLB’s innovative E-Clutch™ technology that allows for the elimination of the PTO while reducing component wear on the power plant.
Other benefits to this design; reduced chassis wiring, and fewer high-pressure hoses and electrical components. A new, lighter weight side-to-side movement front-end arm adds to the high-performance removal capabilities.
- Pumping system generates 13 gpm (49.2 lpm) at 40,000
psi (2,800 bar).
SRV-7 Features Include
- Hydraulically actuated removal assembly with proportional controls.
- Long life UHP seal assemblies with simple to replace seal for ease of maintenance.
- Fully automatic front end service mode makes maintenance and nozzle changes quick and easy.
- Dual heads for maximum productivity. Multiple nozzle bar assemblies available to match any application.
- High resolution touch screen operator interface with adjustable skip line controls allow the operator to advance between skips.
- Hydrostatic creep drive for precise speed control during removal (0-350 fpm).
- Slow running plunger pump built from high-grade stainless steel and provides unprecedented reliability.
- High powered on-board vac unit provides 1,500 CFM.
NLB engineers took the challenge of improved water/debris weight balance head on. By redesigning the truck’s back-end tank and axle configurations to handle the shifts in fresh water reductions and debris collection the axle load does not change during operation. The result is longer operation between water refills and debris removal.
NLB’s new indexing front head carriage traverses side-to-side for automated removal of stop bars.
The ergonomically designed control system puts everything at the drivers finger tips and is available in either single or dual steer configurations.
High resolution in-cab video monitor allows the operator to monitor progress as well as surrounding traffic.
