DECENTRALISED LOW-POWER VARIABLE SPEED DRIVES
Advertisement
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.

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.

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 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 320m 3 /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.

LEVER-ACTION PUMP EXCEEDS DEF TRANSFER SPECIFICATIONS
SKF NOW OFFERS THE LINCOLN model 1392 lever-action transfer pump for diesel exhaust fluid (DEF). This pump is designed to simplify the transfer of bulk fluids to smaller DEF containers or directly into vehicle reservoirs.
“The model 1392 transfer pump was developed to help our customers meet strict diesel emission regulations,” said Keith Rohan, Product Portfolio Manager. “Its seals, hose and nozzle surpass DEF transfer requirements, providing user confidence.”
The pump’s telescoping pickup tube adjusts to fit a wide range of tank depths, increasing versatility. Also, the pump’s locking ring lets the user place the nozzle in the optimum position to reduce pump load.
Its threaded 2-inch bung mounts securely to bulk DEF tanks, providing stable pumping action while also helping prevent contamination that can damage the catalytic properties of DEF. A nozzle hanger keeps the hose within reach and off the floor. The pump package includes a premium non-kink, six-foot hose with ¾-inch outlet nozzle that fits all standard DEF reservoirs. It also has a 45-degree nozzle for dispensing fluid at the pump head.

NEW PRODUCT FOR TEACHING FLUID MECHANICS
TECQUIPMENT, A PROVIDER OF educational equipment for engineering disciplines, has launched a new fluid mechanics teaching product, the Variable Speed Series and Parallel Pumps Bench-top Test Set (H53V).
The set balances the need for a compact teaching product that delivers advanced-level teaching for investigating the operation and performance of a variable speed pump and fixed speed pump that can be used in both series and parallel.
Paul Wilkinson, TecQuipment’s Technical Director, explained: “This is the latest product in the pumps and turbines subrange,
building on the technology of the series and parallel pumps bench-top test Set launched in 2019. Not only is one of the pumps variable in speed, but we have integrated a raft of instrumentation as well, for more advanced analysis of pump behaviour.”
The variable speed pump, electronic instrumentation and integrated VDAS (VDAS Onboard) allows a greater variety of experimentation to be performed, including the demonstration of cavitation.

SUBMERSIBLE PUMP FOR DOMESTIC USE
AS WE SUFFER FROM WET, WINDIER and stormier weather conditions in the UK, is it time for householders in areas vulnerable to floods to consider investing in pumps for emergency use? Or perhaps communities should group together to invest in shared pumps that can be loaned to households susceptible to water ingress?
So far this year, the aftermath of storm Ciara and storm Dennis has left thousands of householders assessing the damage.
The new Sanipuddle from Saniflo is a submersible puddle pump for rainwater that features a flat base which is able to suck away excess water to just 1mm. Pumping water away at up to 5.5m³/hf along the flat, the portable unit can pump up to 7m too if necessary. It can be placed straight into the water to keep levels low, which helps to reduce any damage caused by flood water.
The Sanipuddle can be used to control seepage, rainfall, and rising groundwater without the need for a chamber or sump digging and can be deployed quickly in flood response situations.
