Hydrant and valve inspector

The Flow Control Hydrant and Valve Inspector by Trimble from AMERICAN puts hydrant and valve maintenance and recordkeeping in the hands of the mobile workforce. A barcode scan of an AMERICAN hydrant or grate valve provides its specifications and exact GPS location. 800/326-8051; www.american-usa.com.

 

Basalt-lined piping

Abresist Kalenborn basalt-lined piping lasts five times longer than 1/2-inch wall cast iron, according to the manufacturer. Pipes, elbows and fittings are custom-engineered for each application and can be provided in a variety of end connection arrangements to retrofit into existing systems or install in new systems using flanges, grooved couplings, compression couplings or welded attachments. Most coating systems can be applied to the carbon steel outer casing. The piping is designed for abrasive slurry systems and pneumatic systems in pressure or vacuum conditions. 800/348-0717; www.abresist.com.

 

Dry-run pump

The Dri-Prime NC150M pump from Godwin, a Xylem brand, is a compact pump with flow capabilities up to 1,767 gpm and discharge heads up to 195 feet. The pump features Flygt N-technology with a self-cleaning hydraulic impeller. NC Series pumps deliver high efficiency, resulting in low energy and fuel costs while reducing downtime.

Features include an automatic self-priming system that primes and re-primes from dry up to 28 feet without operator assistance or foot valve control; non-clog performance; Hard-Iron (60 HRC) impeller and insert ring; dry-running high-pressure oil bath mechanical seal with highly abrasion-resistant silicon carbide faces; and close-coupled centrifugal pump mounted to a diesel engine or electric motor for easy pump-end or engine/motor changeover in the field. The pump can be customized with highway trailer, skid-mounted or quiet enclosure. It is also available as a Godwin DBS for pump station backup. 865/467-3636; www.godwin pumps.com.

 

Effluent distribution

The Tru-Flow splitter from Clarus Environmental equally divides effluent under gravity up to five ways while allowing operators to clean and adjust the flow without digging it up. The Spider Valve pressure manifold can be configured to properly split flows to laterals of different lengths on odd-shaped lots. Automatic multizone valve assemblies make large pressure-dosed systems manageable by dividing a system into larger, more convenient zones. 800/928-7867; www.clarusenvironmental.com.

 

Breakage solution

Vertical riser solutions for sewers from Royal Building Products offer a solution to broken sewer pipes and fittings breakage caused by the weight of material placed on top. The risers allow for movement without being crushed by extra weight. The controlled settlement joint allows pipe movement when external soil forces exceed 500 psi. The friction of soil settling drags pipe downward, which can cause fitting breakage. As the sewer pipe is pulled down it can also pull out of the elbow at the top of the lateral causing further failure. The riser adapter, controlled settlement joint and deep bell elbow solve breakage problems.

The riser solution works from 6 to 40 feet depending on the depth of the sewer main installation. It relieves pressure exerted from the static loads created above the installation, such as construction traffic and compaction, while facilitating drag down forces and earth settlement below the surface offering a total solution to potential breakage and pipe push-through. The system allows the contractors to install the riser in a vertical position instead of at a 45-degree angle. 800/232-5690; www.royalbuildingproducts.com/plastic-trends.

 

Compact pump

The Compact pump series from Thompson Pump is available in diesel-drive portable sizes of 4 and 6 inches. The lightweight system offers a small size, few parts and low maintenance. The series includes the Enviroprime system, which keeps pumpage from discharging into the environment. The series is available with automatic start/stop and Silent Knight sound attenuation. 800/767-7310; www.thompsonpump.com.

 

Backup system

The ReliaPrime emergency bypass station from Gorman-Rupp Co. operates on natural gas, making it quiet and environmentally friendly. The unit features a 6-inch Super T Series pump capable of passing 3-inch spherical solids and offers a soundproof, lightweight aluminum enclosure. The enclosure has padlocked door panels and can be removed for maintenance. The unit is a complete backup package, ready for hookup. 419/755-1011; www.grpumps.com.

 

Molded reducing tees

The IntegriFuse molded reducing tees from Integrity Fusion Products are fully pressure rated and available in sizes from 3 inches by 2 inches to 12 inches by 10 inches and all sizes in between. All sizes are available in SDR11 and SDR17. Integrity Fusion HDPE butt fusion fittings are molded out of resin meeting or exceeding PE100/PE4710/PE3608 specifications. 770/634-7530; www.integrityfusion.com.

 

Pipe fusion data logger

The DataLogger 4 from McElroy offers the ability to record and document the pipe fusion process. The unit is smaller than previous generations, has a rechargeable internal battery, double the screen resolution, and a pressure sensor with a 0 to 3,000 psi pressure range. The data logger has multilingual support and recognition of many international fusion standards. The FusionGuide feature gives a fast go/no-go interpretation of graphs generated by the unit. Trained inspectors look at the data to determine if a fusion joint was fused with correct pressures and times according to supported standards. 918/836-8611; www.mcelroy.com/fusion.

 

Tough water pipe

PE4710 water pipe from WL Plastics provides toughness, reliability and durability for extended service life performance. Flexibility and self-restrained joints allow for trenchless installation methods that save time and money versus traditional open-dig projects. The corrosion-free, heat-fused, leak-free joints reduce operations and maintenance costs. 682/831-2726; www.wlplastics.com.

 

Self-rotating nozzles

The Typhoon 10 series of self-rotating nozzles from NLB Corp. clean out blocked tubes and pipes with high-pressure water. They are coated with titanium nitride for long life and come in a variety of drill patterns to suit user needs, from cutting blockages to polishing tube walls.

Model RPN1510, for tubes with a 5/8-inch or larger I.D., is designed to operate at up to 15,000 psi. Model RPN2410 cleans the same size tubes at up to 24,000 psi. Maximum flow for both nozzles is 10 gpm. There are also two models for tubes with an I.D. of 3/4 inch or more. Model RPN1520 cleans at up to 15,000 psi and Model RPN2020 cleans at up to 20,000 psi. Both are designed for flows up to 20 gpm. All models get their rotating action (up to 7,000 rpm) from the nozzle instead of the barrel, focusing the force of the high-pressure water up front. 800/441-5059; www.nlbcorp.com.
