Solenoid valve
Plast-O-Matic has released a new all-purpose PTFE Bellows Solenoid Valve that eliminates fugitive emissions leakage. The thermoplastic valves can be used with all types of fluids, including acids, caustics, solvents, and chlorine solutions. A barrier-type, dynamic seal replaces the elastomer packing of conventional valves. The bellows flex to provide bubble-tight sealing of hazardous fluids and, since PTFE isn’t subject to chemical attack, a working life of over 2,000,000 cycles is normal.

Water quality instrument
In-Situ Inc. announces the release of the Aqua TROLL® 200, a 0.72” diameter water quality instrument designed for monitoring and logging conductivity, level/pressure and temperature in the harshest environments. Building on the successful Level TROLL platform, the instrument features open communications that are SCADA and telemetry ready. Standard output includes Modbus/RS485, SDI-12 and 4-20mA. It’s engineered to combat fouling and conserve power, allowing it to be deployed for extended periods of time. In-Situ Inc., Fort Collins, CO, 800-446-7488, www.in-situ.com
Duplex pump controller
Revere Control’s 100DPLC Duplex Pump Controller is a SCADA-ready controller for lift stations requiring FVNR, RVSS, or VFD motor starting. This PLC-based controller provides a touch screen operator interface for customizing the installation. It’s designed for two pumps (submersible or non-submersible). The operator interface allows the user to customize the installation with operator-friendly screens. Revere Control Systems, Birmingham, AL, 800-536-2525, www.reverecontrol.com
Chemical feed
Along with a new catalog, Chemical Injection Technologies Inc. (CIT) unveils its newly patented SuperiorTM VacuFeed, Gas Detector, High Capacity Gas Chlorinator, and Floor Cabinet. The vacuum liquid chemical feed system assures constant metering of either sodium hypochlorite and calcium hypochlorite solutions, aqueous ammonia, liquid ammonium sulphate, or sodium bisulphite into water or wastewater treatment systems, and many other processes.

Pressurized membrane system
A USFilter technology, Siemens Water Technologies’ Memcor CP pressurized membrane system ensures microbial protection, achieving goals set by the EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR). It’s also well suited for gravity-driven systems, treatment requiring coagulants and pretreatment to RO applications such as desalination and reuse. With a compact, modular design, the system can be installed and started up quickly, and easily expanded to meet future capacity demands without increasing footprint.

Cold weather pump
Thompson Pump & Manufacturing Co.’s new Arctic KnightTM cold weather pump package allows a diesel-driven pump to be used in climates as cold as -40°F to 110°F. Actual desired temperature inside the enclosure can be pre-set and locked to allow for the most efficient operation. The system eliminates traditional problems of operating pumps in cold climates such as frozen liquids in the pump, cracked pump housings, and engine starting problems. It also eliminates the need for expensive and often unreliable accessory items such as block heaters, fuel heaters and glow plugs. Thompson Pump, Port Orange, FL, 800-767-7310, www.thompsonpump.com
Bendable flow sensors
Flexpoint Sensor Systems, which won a 2006 Frost & Sullivan Award for Technology Innovation for Sensors, announced it has been working closely with a pumping systems company in Washington state and is in the final stages of developing a flow meter that incorporates the Bend Sensor® technology. The liquid flow sensor measures the presence or amount of liquid flow in a pipe. Flexpoint Sensor Systems Inc., Draper, UT, 866-766-3539, www.flexpoint.com
Transmitter
The new Model 220 from Mid-West Instrument provides a simple, low cost loop powered 828 VDC two wire 4-20mA transmitter option using the same CSA, UL & ATEX rated sensor and explosion-proof housing used on its Model 220 with switches. The transmitter with an industrial type terminal strip is housed in heavy-duty, cast aluminum housing. Wiring access is through a ½” NPT port. Accuracy is ±2% from 20% to 100% of full scale. Indicator accuracy is ±2% and is independent of the transmitter. Mid-West Instrument, Sterling Heights, MI, 800-648-5778, www.midwestinstrument.com
