Pumping stations in wastewater transport systems are designed to handle raw sewage that is fed from underground gravity pipelines or network pumping stations. Main pumping stations are typically designed so that one pump or one set of pumps will handle normal peak flow conditions. Many main wastewater pumping stations operate with dry-installed pump systems, although submerged pumps systems can offer many advantages for reduced operation costs, enhanced reliability and less infrastructure investment. Grundfos is able to supply complete pumping solutions for both dry and submerged installations.
Grundfos can supply pump systems and pumping solutions for large-scale pumping stations that can be fully customised, both for existing installations and all-new projects, complete with all valves, electrics and pumps that are easy to service.
When designing a pumping station, Grundfos specialists can apply Computational Fluid Dynamics (CFD) simulations to depict accurately fluid flows and pressure graphically at any location in the pipes system. This means that we are able to simulate and discover flow problems in the simulation and correct them before construction begins, building pump pits that function well at low and high flows, and that are self-cleaning, reducing wear and smell by continuously removing deposits and solids.
The Grundfos ranges of SE/SL and S pumps are specifically designed for durable use and heavy, fluctuating sewage flows and can be installed dry or submerged.
Control and monitoring systems increase the potential for improving both efficiency and reliability. Grundfos supplies pump starters and external variable speed drives (Grundfos CUE), Dedicated Controls for easy control of pump functionalities, and internet-based supervision (Grundfos Remote Management) with an easy-to-use SCADA interface.
Grundfos monitoring and control systems include plug-and-play communication interfaces that work with 95% of the communication standards available on the market. A comprehensive range of sensor accessories – such as level, flow and temperature sensors – ensures that you have the data required for your pumps’ control system.
Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits, for optimal operation.
