Allweiler Progressing Cavity Pumps achieve flow rates of up to 500 m³/h.

Sewage transport is a critical process that ensures that domestic and industrial wastewater, as well as rainwater, is transported to the wastewater treatment plant (WWTP) efficiently and without harm to people or the environment. This process involves collecting wastewater from various sources, such as industrial plants and municipalities, and transporting it through a complex sewer system.

Sewage Transport Process Explained

Municipal and industrial wastewater is first collected in local reservoirs. These serve as temporary storage tanks that can hold large volumes of wastewater before it is passed on. The collected wastewater is then transported through a network of sewer pipes. This transport phase must be designed efficiently in order to transport the wastewater over long distances and varying topographical conditions to the WWTP. High-performance pumps are required, especially in geographically challenging areas with large differences in elevation. Progressing cavity pumps are particularly effective because they can reliably pump wastewater even against high hydraulic pressures. Their robust design allows them to handle sewage with high solids content without loss of performance or malfunction.

Pump Requirements for Sewage Transport

Efficient and safe sewage transport requires pumps that meet specific criteria. These include the ability to overcome large differences in elevation, a high pressure rating, and the ability to handle varying levels of solids in the wastewater without the risk of clogging. In addition, the pumps must be robust and adaptable to different and demanding environments.

In cases where the solids content of the sewage is particularly high and conventional centrifugal pumps reach their limits, progressing cavity pumps are the preferred choice. These types of pumps are particularly suited to difficult conditions because they can reliably handle high pressures and pump solids efficiently and without clogging. Their exceptional ruggedness and adaptability make them essential for continuous, trouble-free operation in critical sewage pumping applications.
