WWT PUMP AND VALVE SUPPLEMENT 2019 35 manually reset a fault, unblock an impeller or deal with sedimentation is both time-consuming and costly. It can also be a messy job that nobody particularly looks forward to. That is why having reliable monitoring and control equipment is so important. There's a jungle of products out there from many different suppliers. But how do you know what the best option is for your particular station? The answer to this naturally depends on the complexity of your installation, the importance of keeping it running at all times as well as your budget. For large commercial buildings, hosting many occupants, or for example hospitals or airports it is of paramount importance to have a trouble- free operation that keeps on running at all times: the system needs to offer reliability and efficiency, whilst being low mainte- nance and clog-free. To achieve this, you need an intelligent variable speed drive that is speedy, simple and cost-effective to install. With functionalities developed and optimized to achieve energy savings with maximum cleaning ability. Choose a drive that delivers this and where all parameters are pre-programmed, and all you have to do is press auto for start-up. If you want to go even further, check what a pump with integrated intelligence can do for you. The world's one and only pump range with built-in intelligence is the Flygt Concertor. The cost-effective control system automatically adapts to the changing environment, delivering the optimal level of performance at a low cost of ownership. The built-in intelli- gence also makes it easier to set up and operate as well as allowing for a significantly smaller footprint. The whole idea is to give greater peace of mind while reducing your total cost. 4. Clog detection and automatic sump cleaning Imagine having clean wet wells, clog-free pumping and a reduction in vacuum cleaning call-outs up to 80%. This is all possible if you choose a pump with a built-in clog detection function, which detects when the pump is about to clog and triggers the pump cleaning cycle. A pump cleaning cycle is initiated when a clogging instance is detected and the built-in intelligence will then operate the impeller at different speeds and directions to remove the debris. The sump cleaning function removes floating debris and sediments, eliminating the need for expensive wet well cleaning. The pipe cleaning function assures that pipe sediment is removed, minimizing the risk of pipe clogging. 5. Choose the right hydraulics The pump's impeller is the key to hydraulic efficiency. The Flygt N-impeller revolution- ized wastewater pumping with its sustained high efficiency and self-cleaning operation, that enables a lower total cost of ownership. In the quest for further improvement and reliability, Adaptive N-hydraulics was invented. The Adaptive N-impeller is designed to move axially upwards when needed, allowing the bulkiest of rags and toughest of debris to pass through smoothly. AŠer the debris has passed, the hydraulic pressure returns the impeller to its original position. Ultimately clog-free performance requires almost none, or at the very most, simple maintenance and servicing. Whatever your application you will find that choosing the right impeller makes it much easier to take on the toughest challenges and get the job done. 6. Maintain sustained high efficiency The secret to success is maintaining sustained high efficiency. To achieve this you must consider all the aspects listed above. Invest in a high-quality pump that doesn't break easily along with accessories that work better together. A variable speed drive or built-in intelligence is paramount for trouble-free operation. For convenience and saving money on unnecessary callouts, a clean wet well and a pump equipped with integrated cleaning functionalities are essential. Furthermore, by investing in market-leading hydraulics, you achieve a stable, reliable operation while enjoying peace of mind. Remember that the initial investment on a pumping system is only around 10% of the total cost, while energy consumption accounts for 34%, with maintenance and other operational costs adding up to a significant 56%. In other words, the initial investment is just the tip of the iceberg. In summary, what you invest in products and accesso- ries of great quality with a higher initial cost, you will get back in reliable opera- tion, energy savings and peace of mind.
