Terminal pumping station

Reliable pumping of large sewage flows

Terminal pumping stations receive municipal wastewater from network pumping stations. Installed in dry or wet wells, the pumps forward the medium to a treatment plant for final purification. Due to the lack of screens at most pumping stations, difficult materials such as fibrous sanitary and packaging items are a constant threat to uptime.

The larger size, high sewage flows and long operating hours of terminal pumping stations make reliability the highest priority. Strong links between equipment selection, maintenance and operating strategy are thus required to keep them problem-free.

Sulzer’s application knowledge extends from pumping station design to ongoing optimization. By combining large solids passage with excellent rag handling, Sulzer pumps ensure blockage-free sewage pumping with the lowest lifecycle cost. Sulzer’s easy-to-use pump controllers and monitoring equipment further safeguard and improve station operation.
