High-precision sensor signal conditioner
Progressive cavity series for water & wastewater
ZMD AG (ZMDI), a global supplier of analogue and mixed-signal solutions for consumer, industrial, and medical pump applications, has introduced a 16-bit sensor signal conditioning IC (SSC) for calibrated resistive sensor modules. The ZSSC3016 combines high accuracy amplification, 16-bit precision analogue-to-digital conversion, and an 18-bit DSP for linearization and calibration functions.
Colfax Fluid Handling has introduced the Allweiler All-Optflow series of progressive cavity pumps for waste, wastewater treatment and paper manufacturing.
The sensor is suitable for medical gas control, medical infusion pumps, ambulatory non-invasive pump systems, and occlusion detection systems.
The ZSSC3016 operates at a temperature range of -40°C to +85°C and accuracy is less than ±0.10% FSO over the full temperature range. The ZSSC3016 can perform offset, span, and first and second order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, the ZSSC3016 can provide a corrected temperature output measured with an internal sensor. The measured and corrected bridge values are provided at the digital output pins, which can be configured as I2C or SPI. www.zmdi.com
New design for next generation magnet motors NovaTorque has developed a new design of 3hp and 5hp PremiumPlus+ motors. These induction motors, when driven by variable frequency drives, achieve a motor-only efficiency of between 88.5 and 90.0%. "In addition to having higher efficiency at the rated point, NovaTorque's PremiumPlus+ motors maintain their high efficiency over a much wider speed and load range. For example, in a variable speed, variable torque application such as a fan or pump, a 50% reduction in speed results in a 75.0 percent reduction in load,” said says Scott Johnson, NovaTorque’s vice president of sales. “At that reduced load, NovaTorque motors will maintain efficiency of approximately 91%, whereas a NEMA Premium efficiency induction motor will have declined to 80%.” The NovaTorque motor produces this performance with a cheaper all-ferrite (versus rare earth) magnet design. www.worldpumps.com
"The cost of rare earth (neodymium) magnet material, the basis of most conventional permanent magnet motors, has risen dramatically and is now more than 25 times the cost of ferrite. Further, supply of rare earth magnets, nearly solesourced out of China, is increasingly uncertain. The ability to use ferrite magnets allows NovaTorque to price its motors comparable to induction motors. This means OEMs and HVAC systems builders can now economically deliver permanent magnet motor efficiency with their systems" says Johnson. NovaTorque PremiumPlus+ motors are packaged in standard NEMA frame sizes and mounting dimensions and are available both in the mounting frame size typical for induction motors, as well as one frame size smaller. The magnet motors are compatible with variable frequency drives (VFDs) from most manufacturers, including ABB, Yaskawa, Mitsubishi, Fuji, Hitachi, and Toshiba. www.novatorque.com
The All-Optiflow progressing cavity pumps offer up to twice the flow of standard pumps for applications up to 6 bar (87 psi) and can move virtually any type of liquid, including fibrous and solid materials, with a viscosity up to 300,000 mm2/sec. Its maximum capacity is 3800 l/min. The pumps feature high power density to help reduce energy consumption by up to 15% when compared to standard progressive cavity pumps. The shaft diameters are approximately 30% smaller than those found in standard progressing cavity pumps, reducing friction by nearly 50%. The All-Optiflow series features
redesigned pumping elements with higher power density, lowfriction rotors and shaft seals, and stators with a special surface. This Allweiler pump series can improve the standardisation of structural components, such as a patented stub shaft connection and a lifetime-lubricated joint, allowing operators to move most liquids economically. The stator surface is honeycombed and works in tandem with the patented ‘sharkskin’ rotor surface. This should provide a lower starting and operating torque, allowing the pump to operate at higher efficiency than normal and providing stable performance curves throughout operation. www.colfaxcorp.com

Sliding vane range suitable for asphalt Blackmer says that its NP Series Sliding Vane Pumps have been designed to provide efficient transfer when handling asphalt or bitumen. NP Series pumps are suitable for all of the different transfers of raw products from storage into the refinery, and from process to process within asphalt operations. Blackmer’s NP Series pumps have been designed for the handling of a wide variety of liquids at varying temperatures, pressures and viscosities. They are available in five sizes, with port sizes from 1.5 to 4 in. They feature flow rates
from 5 to 500 gpm (19 to 1,893 lpm) at operating temperatures up to 500°F (260°C), with an optional jacketed pump head for high-temperature operating atmospheres. They can handle viscosities ranging from 30 to 20,000 ssu (4,250 cP) at differential pressures up to 150 psi (10.3 bar) with standard construction, while an adjustable relief valve protects against excessive operating pressures. With optional materials, maximum viscosities can go to 100,000 ssu (22,000 cP) and differential pressures up to 200 PSI (13.8 bar). www.blackmer.com
