The reliable, clean and safe distribution of drinking water to homes and businesses is the obvious first priority of any water supplier. However, leakage and overflow can cost water companies much more than the water lost from the distribution system.
How water is distributed depends on topography and local regulation, and often a mix of gravity pipes and pressure pipes systems are used for the best results. Grundfos can supply pumps and controls for the entire water distribution system, including main and local pumping stations, ensuring reliable management of pressure zones throughout the pipes network.
Grundfos helps reduce costs and limit water loss in a water distribution system by effective pressure control. This is done by compensating for surplus pressure in the pipes system and by reducing water hammer which causes new holes.
Grundfos Demand Driven Distribution is a multi-pump solution operating at proportional pressure, where the system is designed to supply precisely the flow needed at the pressure required, with a number of pumps running at best efficiency point, instead of one big pump. The Grundfos Control MPC provides proportional pressure control, gradual ramp-up and ramp-down, the cascade operation of up to six pumps, and monitoring and control with clear text messages. The Grundfos Control MPC works with all pump types, offering substantial economic benefits from energy savings and reduced leakage losses.
The sustainability of water distribution systems from a source over time requires that the pumping solution is durable, ensuring cost effective and trouble-free operation. Grundfos has decades of experience developing controller and monitoring systems for pumping solutions and manufactures its own pump motors for all fluid types and flow requirements. This ensures a perfect match with hydraulics, motors, electrics, and all other mechanical components that make up a comprehensive pumping solution, ensuring the best possible efficiency point.
The high-efficiency motors developed by Grundfos, with or without an integrated or external variable frequency drive, meet and in some cases exceed the requirements set by motor-efficiency legislation around the world. Considering that on average 85% of a normal pump system's Life Cycle Cost (LCC) is energy costs, switching to high-efficiency motor technology can mean a LCC reduction of up to 50% and a reduction in environmental impact.
Control and monitoring systems increase the potential for improving both efficiency and reliability. Grundfos supplies external variable speed drives (Grundfos CUE), Dedicated Controls and internet-based supervision (Grundfos Remote Management) that are fully integrated into a pumping system. Dedicated Controls enable easy controlling of pump functionalities with an easy-to-use SCADA interface. Grundfos monitoring and control systems include plug-and-play communication interfaces that communicate with 95% of the communication standards available on the market.
Grundfos solutions are designed specifically for pumping installations and all the components are fully integrated from the outset. Life Cycle Cost analyses have shown how this seemingly complex and costly process results in tangible benefits for owners. Grundfos remains with you and your pumping solution for the duration, offering commissioning agreements to ensure correct installation and service agreements offering cover for all eventualities, from routine maintenance to spare parts and pump audits.
