How does a Sewage Pump Work?
A sewage pump is a pump used to move raw sewage from one location to another - for example from a sewage pumping station into the main sewer.
The most commonly used sewage pumps are “free passage” types, which are designed to allow solids to pass through the pump while using centrifugal force to move the sewage to the desired location.
How does a sewage pump work?
Typically, a sewage pump works by using a rotating impeller powered by an electric motor. During operation, pressure generated by the motor allows the water to flow up through the impeller and into the discharge pipe for distribution.
By far the most common type of sewage pumps are centrifugal pumps, which are favoured for their high flow rate and relatively simple operation.
“Free passage” pumps are designed to allow solids to pass through the pump without clogging it and are useful for environments where foreign matter such as tampons, sanitary pads and toilet paper may be encountered, providing the passage is large enough.
Types of sewage pump
Most sewage pumps are electric submersible pumps, but it’s also possible to source surface-mounted models depending on your requirements. Sewage pumps may be automatic or manual.
T-T Pumps supplies a wide variety of sewage pumps available in various configurations to suit differing applications. Some of the most common types of sewage pumps include:
Simple sewage pumps that are suitable for normal effluents.
For challenging applications with fibrous materials.
Ideal for smaller bore rising mains with high heads.
For harsh environments containing high density fibrous materials.
Choosing the right sewage pump
The right sewage pump will depend on your individual environment and application. Over the long term, a good selection will ensure reliability and the maximum return on your investment. Read our handy guide, How-to: Select a Sewage Pump, for more information.
