		Pump Units NLB pumps have set the standard for performance and reliability since 1971. Our triplex and quintuplex plunger models operate at low rpm to minimize wear and simplify maintenance. These proven designs are regularly updated with the latest materials and features to keep operating costs as low as possible. Units for any application, up to 40,000 psi With 40 units to choose from - 22 of them convertible to different pressures and flows - NLB pumps can handle just about any application you throw at them. Many are available with either a hard-working diesel engine (trailer-mounted for easy towing to job sites) or an energy-efficient electric motor. Either way, you get: 97% operating efficiency - Advanced engineering means minimal turbulence and 97% efficiency at 10,000 psi. Long-life materials - Valves and more are precision-machined of high-grade stainless steel, and hard-coated for durability. Simple maintenance - Time-saving features include 5-minute packing change. Rebuild to extend ROI - After 20,000 hours, some pumps are done for. Ours are designed to be rebuilt and keep on working. NLB pumps are built for continuous, trouble-free operation, using a simple design proven in countless applications over more than three decades. Their mechanical efficiency is simply outstanding. One reason is a heavy-duty power frame that provides stability, gravity lubrication, and easy access to take out packing and plungers for inspection… without removing the stuffing box. Although these pumps were designed for NLB units, they also make great replacements when pumps wear out in other manufacturers' units.




		Bare Pumps The heart of any NLB water jetting system is the pump, and ours are well-known for reliability and longevity. Their slow-running design minimizes wear and maximizes service life. So when it is finally time for a replacement, why choose anything else? In fact, with the full line of convertible pumps NLB has, we can usually replace an older NLB triplex or quintuplex pump with a new convertible model to give you operating pressure flexibility and ease of maintenance. And if you own a non-NLB unit, does the pump give you problems? Perhaps it is time to consider replacing it. NLB pumps last longer, cost less to operate, and provide a user experience unsurpassed in the industry. Actual pump capacity is approximately 95% of the displacement. Horsepower can be computed by using the formula: BHP = (GPM x PSI) / 1715




		Hand Lances Lances are the basic tools of water jetting, and NLB offers more choices — with more safety and ergonomic features — than any other manufacturer. From adjustable grips and shoulder supports to trigger locks and a patented quick-change cartridge seal, NLB leads the way in , operator protection and comfort. This section features lances that work with a wide range of nozzles — 1 dual-trigger, underwater dump, and I shut-off models. All feature rigid stainless steel construction with quick-coupling hose hook-up. Also in this section, you'll find related accessories — a 40,000 psi rotating lance, vacuum attachment, lance stands, and whip hoses.




		Spin Nozzle® The NLB SPIN-NOZZLE® self-rotating head (U.S. patent no. 4,821,961) turns an ordinary high-pressure lance into a superior water jetting tool. The SPIN-NOZZLE features a specially designed and balanced body, threaded for two standard jetting nozzles in an offset pattern. The SPIN-NOZZLE rotates by the reaction energy of the high-pressure water; no external driver is needed. Features and Benefits Faster production rates due to wide spray pattern and force Reduces back thrust for operator Self-lubricated




		Standard Nozzles When it comes to nozzles, "standard" doesn't mean off-the-shelf. While NLB standard nozzles are designed for general use (instead of specialized uses like pipe cleaning or abrasive cutting), each is custom-sized to suit your application. When ordering, be sure to consider not only the pressure and flow rate of your pump unit, but the actual pressure at the nozzle, which is always lower. Our standard nozzles have a single orifice that can provide either a tightly focused 0° stream or a 15° fan spray, depending on your requirements. The five shown below are designed for a maximum pressure of 20,000 psi (1,400 bar), and simply screw on the end of any NLB lance (and other tools) rated for that pressure. For pressures up to 40,000 psi (2,800 bar), we offer UHP 0° and 15° nozzle assemblies. Both attach easily to our NCG40-286 lance.




		Abrasive Nozzles The NLB wet abrasive blasting systems combine the force of a high-pressure water jet with the cleaning action of abrasive media — without the dust, costs or health and environmental hazards associated with dry sand blasting. Wet abrasive blasting can clean steel to a white metal finish or remove tightly bonded paint from concrete, steel or masonry. NLB offers 10,000 psi, 20,000 psi and 40,000 psi abrasive nozzles (700, 1,400 and 2,800 bar), with rebuild kits. A hopper is required to hold the abrasive media, whose flow rate is variable with the metering disc used (see next page for hoppers and discs).




		Foot Controls When an operator has both hands busy (while cleaning tubes and pipes, for example) a foot control valve lets him control the water flow. NLB offers five models — dump-style and shut-off style — for applications from 10,000 to 40,000 psi (700 to 2,800 bar). Dump-style valves allow instantaneous dump to low pressure when the foot pedal is released, and include a muffler to minimize hydraulic shock. Shut-off valves minimize the water in the work area because the dump is initiated some distance away, by an unloader valve.




		Flow and Pressure Multi-gun valves let you feed two lances at once from a single high- pressure pump unit. Unloader valves (with a system valve) divert pressure back to the tank in automated applications. Pressure reducing stations allow accurate pressure and flow adjustments when the pump is not located near the work being done.




		Flex and Rigid Lances Choices for Every I.D. and Operating Pressure NLB flex lances have been proven time and again over the past 35 years. Key features include smooth inner core that minimizes pressure drop and a compact end connection to handle a tight bend radius. RP hose has an abrasion-resistant nylon outer cover with a smooth surface that reduces friction as it travels through the pipe or tube. SRV hose features two outer spirals of high-tensile stainless steel wire, for added kink resistance. Our ultra-high pressure flex lance features six layers of this wire. NLB flex lances are stocked in 25' and 50', and are also available in lengths up to 200' (7.6m and 15.2m, up to 61m).




		Pipe and Tube Nozzles The nozzles shown on the next few pages are designed to work with NLB flex and rigid lances. All thread on easily and deliver a spraying pattern optimized for your application; the pipe cleaning nozzles also provide back pressure to propel themselves through clogged pipes. Each NLB nozzle is custom- drilled, using precision machining techniques, to your specific pressure and flow requirements. Standard drill locations are Straight, 45° Front, 90°, and 45° Back, with as many orifices as the job demands. If you are not sure of the best pattern, NLB will be pleased to recommend one. We can also help you choose the best nozzle for a your tube or pipe I.D., and for your high-pressure pump unit.




		Tube Lancers NLB's semi-automated tube lancers not only clean heat exchanger tubes up to three times faster than manual methods, they minimize operator exposure to debris or high-pressure water. They make short work of long tubes. A tube lancer inserts from one to seven rigid lances into the tube bundle, following a pre-programmed pattern if desired. X, Y and Z movement is pneumatic, controlled by an operator from a remote console. An optional station with seat and climate control is available with some models. NLB units are portable and easy to set up. They are made primarily of heavy-gauge aluminum to resist corrosion; horizontal configuration is standard.




		Shellside Cleaners High-pressure water jetting brings the same benefits to exterior heat exchanger cleaning as it does to tube lancing. NLB has two automated shellside cleaners, which move nozzles robotically from one end of a tube bundle to another to blast away hardened deposits. Key benefits include: More thorough and productive than manual cleaning Minimizes operator risk from debris and high-pressure water Cleans bundles up to 25 feet long (7.6 m) Hydraulic crane positions cleaning head No electrical hook-up required All operating controls on a convenient console Custom-engineered systems available




		Abrasive Cutting Whether you need to cut through metal, concrete, composites, or another hard material, use an abrasive cutting system from NLB. Our high-pressure and ultra-high pressure water jets (up to 40,000 psi, or 2,800 bar) can slice through thick concrete with rebar, or cut inspection openings in petrochemical storage tanks. NLB can provide a complete system, from cutting nozzles, track crawlers (for automated cutting) and hydraulic control unit to feed hoppers and metering discs. Features include: Choose from 20,000 psi or 40,000 psi (1,400 or 2,800 bar) Adjustable nozzle angles and tracking speed Cuts round or flat materials Air or hydraulic drive




		Spin Jet® Floor and Grate Cleaners NLB's patented SPIN JET® rotating spray system has long been one of the water jet industry's most effective tools. Our SPIN JET® floor and grate cleaners (maneuvered like a lawn mower) were originally designed to remove overspray from paint booth grates. Today they are also widely used for removing floor and ship deck coatings, highway stripes, runway rubber, and more… and even for concrete scarification. SPIN JET® units reduce labor, operating costs and energy use. We offer seven ergonomic models with a range of pressures, flows and cleaning path widths. Standard features include a dump valve that instantly reduces water pressure to near-zero and shields over moving components, hose and quick-disconnects. Rotary seal and dump valve repair kits are available. Options include 4-arm and 6-arm configurations and pneumatic or hard rubber tires. Some models have vacuum recovery.




		Spin Jet® Plate-Mounted Rotating SPIN JET® units are often mounted in place for automated water jet applications, such as parts and fixture cleaning systems, or casting removal. NLB custom-engineers these systems to meet individual application requirements and specifications. For detail areas requiring precise control, smaller units can be mounted on robots. Key features include: Range of pressures — 10,000 to 40,000 psi (700 to 2,800 bar) — and flows Choice of self-rotating, air, electric, or hydraulic Versatile mounting bracket adapts to a wide range of fixtures Quick-change packing for fast, easy maintenance Rugged stainless steel housings




		Stack and Pipe Cleaners A self-rotating seal with NLB's patented SPIN JET® technology is the most efficient way to clean large pipes and stacks. As a towline pulls it through the pipe, spray arms (2 or 4) rotate high-pressure water jets 360° for full coverage. The rotational speed is adjustable up to 3,000 rpm. Choose from 10,000 psi or 20,000 psi models (700 or 1,400 bar), with many popular features: 2 or 4 spray arms Various nozzle offsets available Operates with cold or hot water Built-in magnetic brake to adjust rotating speed up to 3,000 rpm Rugged stainless steel construction Optional, adjustable guide to center seal in pipe Quick-change packing through top cap Reconfigurable nozzle blocks for arms up to 15" (38 cm) long




		Tank Cleaning NLB's 3-D tank cleaning dramatically reduces tank cleaning time, respects the environment, and eliminates the need for anyone to enter a confined space. The dual cleaning action of the revolving/rotating head, powered by the reaction force of the high-pressure water jets, provides complete, 360° interior coverage of your tank or reactor. NLB's 3750 3-D heads have been removing the toughest chemical and resin build-up for decades — everything from ABS and PVC to baked-on coke. Some customers have reduced man-hours by as much as 80 percent, while others report that they clean 6 times as many tanks or totes with water jets as with caustics or solvents. We offer a complete system, with a selection of 3-D heads and telescopic lances plus swivel turrets, protective cages, and a variety of nozzle arms and extensions to suit practically any application.




		Pump Controls Some of the most important contributions to pump performance and safety are made by components you hardly ever notice. NLB pump controls can keep your unit operating reliably, year after year. They have earned a reputation for precision, durability and — wherever possible — ease of replacement. In this section of the catalog you'll find by-pass valves and pulsation dampeners to regulate and cushion the flow of high-pressure water, gauges to monitor operating pressure, and snubbers to enhance gauge accuracy. Rupture disc assemblies relieve pressure in the event of a spike, while shut-off valves quickly close line flow. We also offer engine throttle controls, filters to keep pumps free of dirt, and system valves for remote control of water flow.




		System Valves When operators are working some distance from a pump unit, the ability to stop the high-pressure water flow without shutting down the pump is a real convenience. That's where NLB system valves come in. They handle a wide range of flows and pressures, and you can choose from six actuation methods (see below). Some models can be equipped with proximity switches; some are even explosion-proof. Although usually mounted on a remote workstation, a system valve can be mounted on the pump. Features and benefits include: Stainless steel construction of all wetted components Standard enclosures protect in hostile environments Used with electric units for "no-load" start-ups Rebuild kits available for fast, easy maintenance




		Filters Dirty water can be the worst enemy of a high-pressure pump, but you can rely on NLB filters to keep it clean. Choices include bag filters, screen filters and cartridge filters that can trap particles as small as 3 microns. Replacement gaskets and elements are available for all. For special conditions, please give us a call.




		Hoses NLB stocks a complete line of high- pressure hoses for all popular working pressures, up to 40,000 psi (2,800 bar). All are designed for long life and dependable service. Most hoses are stocked in 25', 50' and 100' lengths (7.6m, 15.2m and 30.4m), and custom lengths are available. When ordering, please specify part , number, length (the XX at the end), and end connection. Features include: Smooth inner core to minimize pressure drop High-tensile spiraled wire for strength and kink resistance Tough outer cover to prevent abrasion and wire exposure Short end connections allow movement around tight bend radii




		Couplings and Fittings NLB can supply hose connections for virtually any water jet connection — couplings for up to 20,000 psi (1,400 bar) and fittings for ultra-high pressure, up to 40,000 psi (2,800 bar). Couplings are available in quick-disconnect (sleeve-lock) and wing union (hammer-lock) styles, with economical o-rings for field repair.




		Safety Safety has been a priority at NLB since the company began in 1971. In addition to the many design features we integrate into our water jetting pumps and accessories, we offer customers a full line of tools to maximize jobsite safety. These include everything from space-age protective suits designed to withstand the impact of a 40,000 psi (2,800 bar) water jet to simple signs and barriers that help keep everyone aware of potential risks.




		HydroPrep™ NLB's versatile HydroPrep™ system is the most efficient way to remove coatings (paint, epoxies, etc.), scale, and other tough adherents. Our automated and semi-automated accessories, connected to a rugged NLB high-pressure water jet pump unit, leave metal and concrete undamaged and ready for recoating. (Steel is left with a "white metal" finish, per NACE, SSPC and SIS standards.) Using nothing but ultra-high pressure water (up to 40,000 psi, or 2,800 bar), HydroPrep™ is as productive as grit blasting. Yet it saves you the associated expense, risks (environmental or sparks) and clean-up problems. You choose the level of automation you need, and vacuum recovery is available.




		Vacuum Recovery Vacuum recovery of debris and water lets you respect the environment while enhancing safety and productivity. NLB offers several vacuum systems with capacities and degrees of mobility to suit your needs. This equipment is most commonly used with our HydroPrep™ surface preparation systems and STARJET™ pavement marking removal systems, but has also proven itself in other applications.




		Stripe Removal For over a decade, NLB has pioneered the removal of pavement markings with ultra-high pressure water jets. We have two mobile systems, both with rotating SPIN JET® assemblies mounted on a vehicle, connected to a water supply and NLB pump unit. The STARJET™ does high-volume removal (like highways and runways), while the compact STRIPEJET™ is ideal for parking garages and intersections. The STARJET™ system has all components — patented nozzle assembly, UHP pump unit, water tank, and optional vacuum recovery — on a heavy-duty truck. It can remove up to 7,000 feet of markings per hour (2,134 meters per hour). All operating controls are conveniently located in the cab. The STRIPEJET™ is very maneuverable, with a tight turning radius and smooth, consistent speed. Five heads are available for each system, for cleaning paths of 8", 10", 15", 20" or 24" (20, 25.4, 38, 50.8, or 61 cm). Vacuum recovery is optional.
