Dolphin liquid-ring vacuum pumps (photo) are available as a single-stage version in block design (Dolphin LC) and in a base-plate design (Dolphin LB) in either single- or two-stage variant. Capacities of between 25 and 5,100 m 3 /h are covered by this new Series of pumps. The LA/LB Series are also available in an ATEX-certified version. Three modes of operation are possible: a through-flow system, where service water is fed continuously, and then discharged together with the extracted gas; open circuit, where service water is separated from the gas in a down-stream vessel, then fed back to the pump; and closed circuit, whereby service water is separated from the gas, then runs through a cooler before returning to the pump. The open circuit option is said to make savings on water service of up to 90% possible. The pumps achieve pressures of 33 mbar; when combined with a gas ejector, the ultimate pressure can be reduced to 8 mbar. — Busch Vacuum Pumps and Systems GmbH, Maulburg, Germany

The Rosemount Analytical Model 6081-P wireless pH transmitter (photo) is the latest addition to this firm’s Smart Wireless plant solutions. The new field device — said to be industry’s first wireless pH/ORP transmitter — measures both pH and ORP and is compatible with most Rosemount Analytical pH and ORP sensors. The transmitter installs easily and joins the wireless network quickly, enabling analytical measurements that were previously impossible due to physical or economic constraints, or in movable applications. Installation savings are as much as 90% as compared with traditional wired service. — Emerson Process Management, Bredbury, Stockport, U.K.

The sealless, leak-free TopGear MAG internal gear pumps are specifically designed for handling low or high-viscosity hazardous or toxic liquids, or for liquids that are problematic to seal off. The pumps provide a maximum capacity of 80 m3 /h, a maximum differential pressure of 16 bar and can operate with liquids with a maximum temperature of 250°C.On important feature of the pump is the gap between the inner magnet and can, which minimizes friction losses when pumping viscous media, thereby ensuring low heat generation and long life operation. The pumps are available with silicone carbide bearings, and a built in safety system prevents both the inner and outer magnetic rotors from running against the can in case of bearing failure. — JP Pumps Ltd., Crawley, U.K.

The KTEK range of laser-based instruments (photo, p. 40I-10) has been expanded with the addition of a new 2D volume flow scanner and a 3D laser-belt scanner. The LM080 laser-belt scanner provides a continuous, non-contact volumetric flow measurement (m3 /h) of bulk solids lying on belts and conveyors, while simultaneously monitoring the belt speed. The result is a 2D cross-sectional area of bulk material, while the belt speed provides a 4 – 20-mA output that is scaled in cubic meters per minute. Unlike alternative volumetric measurement technology, such as gravimetric weighing, the KTEK scanner is unaffected by vibrations. The LM050 is a moving 3D laser scanner that provides continuous, non-contact mapping of entire stockpiles. Each laser uses a large number of measurement points to accurately profile and measure volume to an accuracy of ±0.5%. — Allison Engineering, Basildon, U.K.

The Atlas pH Monitoring and Control System (photo, p. 40I-13) offers chemists a simple and reliable tool for chemical synthesis. Intelligent, PC-free control allows efficient maintenance of pH via realtime detection, display and adjustment, with automated addition of acid or base using the Atlas Syringe Pump. The unit was developed for the accurate control of pH throughout the most sensitive of reactions, says the manufacturer. Temperature and pH probes connect to the Atlas base, where parameters such as temperature, stirrer speed and quantity of acid or base can be accurately and consistently controlled. — Syrris Ltd., Royston, U.K.

Automatic Magnetic Drains (AMDs) remove condensate and other contaminates from air systems, thereby protecting valuable equipment. The AMD 1550 drain trap has working pressures to 230 psig and a discharge capacity of 53 gal/h. Designed for use with coolers, refrigerated dryers, separators, filters and liquid separators, the AMD 1550 maintains a liquid seal that prevents the loss of compressed air to save energy. The rugged and corrosion-resistant metal housing allows for a long lifetime of service, and operating mechanisms are isolated from condensate so that no fouling or sticking occurs, thus minimizing maintenance. — Kaeser Compressors Inc., Fredericksburg, Va.

Available in sizes up to 12 in., this corrosion-resistant valve incorporates a double eccentric operating principle that provides improved wear and easier operation. The off-center shaft allows the disc to completely disengage from the disc seal, even when partially open. This reduces seal friction and improves seal wear characteristics, resulting in longer service life, minimal maintenance and better protection against pressure surges. Typical applications include: industrial water treatment; potable water treatment; swimming pools; water parks; and wastewater systems in such industries as chemical, chemical distribution, electroplating and power generation. — GF Piping Systems, Tustin, Calif.

The ESX10-T electronic circuit protector is a compact device that combines purely electronic trip characteristics and active current limitation to allow selective disconnection of loads connected to 24VDC power supplies. Selective-load protection prevents complete shutdown of the system by quickly disconnecting the faulty path when an overload or short circuit occurs. It limits the highest possible current to 1.3 – 1.8 times the rated capacity and is capable of switching on capacitive load up to 20,000 µF, with disconnection only in the even of an overload or short circuit. Upon a need for disconnect, the power-MOSFET switching output of the ESX10-T interrupts the current flow at 1.1 times rated current after three seconds. — E-T-A Circuit Breakers, Mt. Prospect, Ill.

The Gladiator smart admittance level switch is designed to detect the level of liquid, slurry or powder in a tank or vessel. The unit measures the capacitance or admittance between a probe and the wall of the container. As the level of the product rises to the level of the probe or drops below the level, the capacitance measured at the probe changes. When the Gladiator detects these changes, it produces an output. It can monitor materials with a wide range of dielectric constants, so the system is applicable to a large variety of liquids, slurries and powders. — Hawk Measurement, Middleton, Mass.

A high-efficiency, energy-saving, tower-type oil pump has been developed that is driven by permanent magnetic linear motors. According to the manufacturer, it is the world’s first vertical oil pump to adopt a large-thrust cylindrical synchronous linear motor. In addition to producing measurable energy savings, the pump offers automatic and reversing speeds, as well as reduced operational maintenance expenses. The patented system gauges the tension needed to mechanically lift liquid out of the wellhead and makes adjustments to the power needed in real time. The firm promises more than 20 – 30% of energy conserved when compared to traditional oil pumps. The units, which are certified by Heilongjiang Science and Technology Bureau (HSTB), a branch of the Ministry of Science and Technology of P.R. China, and China National Petroleum Corporation Daqing Petroleum, are expected to sell at an average price of $52,000. — Harbin Electric, Inc., Harbin, China
