NEW VARIABLE SPEED DRIVES HELP OVERCOME HARMONIC CHALLENGES
Advertisement
ABB’S ACQ580 RANGE OF VARIABLE speed drives (VSDs), developed specifically for pumping applications in the water and wastewater industry, now includes an ultra-low harmonic (ULH) version. This new drive ensures reliable operation even in unstable power supply conditions by keeping the network clean from troublesome harmonics without the addition of filters or special transformers.
The use of VSDs with motors that operate pumps and blowers offer significant benefits for a water plant, including enhanced energy efficiency, better control and reliability of operations. The issue is that VSDs can also introduce harmonics into the electrical network.
Harmonics can damage sensitive electronic equipment, trip circuit breakers, blow fuses and cause capacitor failures. They can also interfere with communication systems and cause false readings on measurement devices. In the worst cases, harmonics cause costly process interruptions.
The traditional approach to tackle problems created by harmonics is to add filters, multipulse transformers or overdimensioning equipment. However, the ABB ACQ580 doesn’t need external filters or any special equipment.
“The new ABB drive has harmonic mitigation built-in, including an active supply unit and integrated low harmonic line filter,” says Simo Niskanen, Drives Product Manager, ABB. “Compared to a conventional drive, the ACQ580 ULH can reduce harmonic content down to 3% THDI (total harmonic distortion of current).”

DRIVE FOR DEMANDING ENVIRONMENTS
TEC MOTORS HAS INTRODUCED an IP66/NEMA 4X rated version of its general-purpose TECDrive Variable Speed Drive (VSD). Offering the same energy savings, ease of installation and intuitive user experience as the standard model, the IP66 TECDrive VSD is specifically designed for tough applications where durability and reliability are paramount.
The IP66 TECDrive VSD has been designed to work outside the control cabinet environment and can be mounted almost anywhere. It will withstand outdoor conditions and regular low-pressure washdowns thanks to its high ingress protection rating, tough polycarbonate enclosure and corrosion-resistant heatsink. The enclosure is UV stable and impervious to dirt, grease, oils and
weak acids. It also has a wide operating temperature range from -10 to +50°C. TEC says that a key advantage of the new drive is its ease of installation, allowing general-purpose users to start benefitting from energy savings and motor speed control quickly. There is a clear LED display with waterproof buttons for basic settings, plus, the option on every model to include a manual run/reverse switch and speed control potentiometer. There are four frame sizes available with power ratings from 0.37kW single phase, up to 22kW three-phase all available from UK stock.

PUMPS MINIMISE DOWNTIME IN OIL & GAS EXPLORATION
ENGINEERED TO MINIMISE downtime in offshore applications, SPX FLOWs ClydeUnion Pump CUP-BB5 range features a cartridge retention design that means a complete rotor change-out can be completed in under eight hours.
The CUP-BB5 range comprises radially split, diffuser type, multi-stage pumps specifically designed for the oil & gas market. With capacities up to 2,800m 3 / hr and delivery heads up to 4,100m, typical applications for the CUP-BB5 range include produced water injection, seawater injection and main oil lines.
CUP-BB5 pumps require no specialist tools or additional training, making maintenance straightforward and minimising downtime. The shear ring locking system ensures rapid change-out and minimises pump downtime because it does not require the use of high torque equipment to assemble or dis-assemble.
With two main variants of in-line impellers (CUP-BB5i) or a back-to-back impeller arrangement (CUP-BB5b), the pumps are available as engineered-toorder solutions, fully compliant with the latest API 610 and API 682 requirements and customer specifications. The CUP-BB5 can also be packaged with various types of drive equipment to suit customer requirements. Typical options include fixed or variable speed electric motors, combustion engines and gas or steam turbines. Packaged systems are further equipped with a range of pump healthcare monitoring equipment to enable measurement and analysis of performance data to aid preventative maintenance and increase availability.

NEW CLAMP-ON ULTRASONIC FLOW METER FOR LIQUIDS
BELL FLOW SYSTEMS has announced the introduction of the Dynasonics TFX-5000 ultrasonic clampon flow and energy meters manufactured in the United States by Badger Meter.
Designed for noninvasive, ultrasonic transit time flow measurement of liquids, these flow meters are suited to use in water and wastewater treatment, heating/ventilation/air conditioning (HVAC) and oil and gas applications.
TFX-5000 ultrasonic clamp-on flow and energy meters measure volumetric flow and heating/cooling rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water or raw sewage. Typical applications include water mains, reclaimed water, lift stations and booster pump stations in water and wastewater, or the energy transfer of chilled water and glycol/hot water in HVAC systems, as well as produced water in oil and gas applications.

SUBMERSIBLE DEWATERING PUMP RANGE EXPANDED
SULZER’S NEW XJ 900 SUBMERSIBLE DEWATERING pump is an extension of the XJ series of pumps which were first brought to market in 2012. The company is positioning the new pump as an economical and reliable option for dewatering applications which, it says, is a valuable asset against waterrelated downtime.
The new pump is equipped with a high-efficiency electric motor rated 90kW for 50Hz markets and 108kW for 60Hz markets. The highefficiency IE3 motor and new hydraulics combined with lowfriction bearings reduce power losses. As a result, the total energy costs are low, and the carbon footprint is reduced. The pump’s hydraulic design allows for easy conversion between high-head and high-flow configurations. This makes it possible to stock fewer pumps and still have the right hydraulic performance for the job.
