DECENTRALISED LOW-POWER VARIABLE SPEED DRIVES WEG HAS LAUNCHED A NEW addition to its MW500 series of variable speed drives (VSDs). Designed for decentralised installation, the MW500 VSDs are now available for operating induction motors with low power in the range of 370 to 550W. The MW500 supports both voltage vector control (VVW) and V/f characteristic curve control and offers a robust and durable solution. The VSD can handle an overload of 150% for 60 seconds every ten minutes and can be deployed at ambient temperatures — up to 40°C wall mounting or 50°C for motor mounting. A sturdy housing design with protection rating to IP66 or NEMA 4X allows the VSDs to be mounted directly
on the motor terminal box or the wall using an adapter plate. This eliminates the need for a motor feed cable and switch cabinet, allowing users to install the drive close to the controlled motor, increasing deployment flexibility. The standard version of the MW500 comes with a PID process controller and an integrated PLC with numerous programming functions. The device includes an EMC filter compliant with EN 61800-3. An analogue speed control potentiometer is also included in the drive to enable setting the speed of an induction motor without the need for a control panel if desired. To ensure maximum flexibility, digital I/O and communication protocols such
as CANopen, DeviceNet and Profibus DP are available as optional extension modules. The Windows-based SuperdriveG2 application software for programming, control and monitoring of the MW500 is available to customers on the WEG website as a free download. www.weg.net
INTERNET-BASED WASTE WATER SYSTEM MONITORING CAMPION PUMPS HAS INTRODUCED MyScadaCloud, an internet-based system for monitoring and managing water and wastewater systems. Capturing live data and delivering early warnings, MyScadaCloud gives users the ability to detect issues before they become system failures and to monitor trends in system outputs and data, without having to send an engineer to site. To enable the MyScadaCloud’s functionality, a water system is fitted with a wireless communication unit. An engineer will then install a smart data logger which gives the system a
pulse and opens communications to a cloud server. The cloud servers receive data from the water system wirelessly
which is then captured and analysed by MyScadaCloud as live data, every 15 minutes. Based on parameters set by the user, the application flags excessive or irregular behaviour in the water system – analysing the information it receives and issuing warnings of changes in normal patterns or functionality. Users then have full remote control over their water system. The system, which is not specific to any hardware or software platforms, offers real-time information, 24/7 visibility and the secure backup of all data. campion.ie
SUBMERSIBLE MOTOR PUMP TO SHOWCASE AT IFAT KSB GROUP WILL BE SHOWCASING its new Amarex submersible motor pump at the IFAT exhibition which takes place in Munich from May 4-8 this year. The pumps are designed for applications like waste water and sludge treatment as well as the transport of stormwater. They can handle waste water with long fibres and solid substances, fluids containing gas as well as sludges, service water and grey water and are equipped with either free-flow impellers (F-max) or open two-vane impellers (D-max). This means that customers can choose the right impeller type depending on their requirements – low waste water flow rates at high Quarter 1 2020
heads and high flow rates at lower heads. Pump variants featuring D-max impellers are also available with D-flector, which significantly increases resistance to clogging. A multitude of material and mechanical seal variants ensures that the user can transport a wide range of corrosive and abrasive fluids. The impellers’ nonclogging feature markedly reduces maintenance requirements compared
with conventional designs and the pumps’ high levels of hydraulic efficiency combined with highefficiency IE3 motors make for low energy consumption during operation. The series has a maximum head of 42m and a maximum flow rate of 320m3/hr. When designing Amarex, engineers attached great importance to the pumps achieving a long service life. This is ensured by a generously dimensioned motor, robust rolling element bearings and a corrosion-resistant stainlesssteel shaft. www.ksb.com/ksb-uk www.bpma.org.uk
