The Chemicor series of metal pneumatic diaphragm pumps is designed for handling and transferring chemicals. The pumps’ components include stainless steel precision-cast housing, diaphragms of ethylene propylene diene monomer (EPDM) and polytetrafluoroethylene (PTFE), and ball valves consisting of EPDM and PTFE. Units are available in three volume sizes, including 75-L/min–20-gal/min (AD 20); 150-L/min–40-gal/min (AD 32); and 400-L/min–100-gal/min (AD 50). Almatec®Maschinenbau GmbH (Kamp–Lintfort, Germany).
Asset Management Software
The VUEWorks® 2009 scalable suite of software modules for managing work processes, capturing citizen concerns, and executing preventive maintenance enables companies and organizations to track the condition, minimize the risk of failure, prioritize expenditures, and manage service delivery of their physical assets. It enables organizations to retrieve key asset data, apply work-management practices, and develop strategic asset management programs for any infrastructure physical asset. A new Facilities Module provides flexible tracking of any asset that is typically not identified as part of the geographical information system (GIS) data. Facilities can be linked to GIS assets for easy selection from the map. Individual assets — such as pumps, motors, valves, switches, and controls — can include values for condition, valuation, and work history. Users also can create multiyear budget scenarios based on deterioration curves and automatically trigger different types of repair options, based on where the segment falls on the deterioration curve.

The TranStar Steerable Tractor for video pipeline inspection is equipped with two 90-watt rare-earth permanent magnet motors. Designed to work with RS Technical Omni III, NovaSTAR, and TrakSTAR cameras, it provides inspection capability in sanitary or storm lines 6 to 30 in. in diameter and up to 3000 ft in length. The TranStar can turn on its own axis and travel up to 60 ft/min with three forward speeds, reverse, and freewheel. RS Technical Services Inc. (Petaluma, Calif.).
The Gemini 720i multibeam imaging sonar is designed to combine the benefits of long-range detection with high-definition imaging techniques. With a lightweight, compact design, the sonar can be deployed on most remotely operated vehicle and autonomous underwater vehicle platforms. Weighing 1.2 kg in water, Gemini is supplied with Ethernet and very-high-bit-rate digital subscriber line communication modes, which offer the option to communicate either through fiber-optic cables or long-distance twisted-pair channels, depending on the configuration of the umbilical. The introduction of a curved transmit transducer array ensures that acoustic energy power is evenly transferred across a wide-swath imaging sector, speeding up search and navigation operations. To sharpen up the acoustic range resolution, an innovative sound-velocity sensor has been integrated into the design to monitor the local velocity of sound conditions. Tritech International Ltd. (Aberdeen, Scotland).
The Series 3500 two-way, two-position solenoid–air operated pilot valve is suitable for air control, inert-gas control, water, condensate drainage, hot-water plumbing, and sprinkler systems. The 3500 has an ambient temperature range of –10°C to 50°C. When combined with the Series 3000 solenoid operator and used as a direct acting–pilot operated valve, the 3500 gives full flow throughout a pressure range from zero to 230 lb/in.2 Available in 0.25-, 0.375-, and 0.5-in. National Pipe Thread sizes, the valve features high life-cycle solenoid parts, a push, and nonlocking manual override. Spartan Scientific (Boardman, Ohio).
