Sewage Transfer Guide
Sewage pumps are used to transfer sewage from domestic and commercial tanks which are located below existing sewage networks. Properties can be located in areas which are lower than exiting sewage pipe meaning gravity drainage can not be used. Pumps transfer sewage at high flows, and low heads to the existing sewage network which flows into sewage treatment plants for processing.
Differing pump types are used for sewage depending on the pipework size available and types of solids. Sewage mostly consists of clean water with solids in suspension which allows centrifugal type pumps to be used.
Macerator type submersible pumps are used in areas where there is only small pipework available and the pressure required is quite high so solids are macerated to ensure the fluid can be transferred long distances. Often macerator pumps are used in properties where a toilet is added into a basement. Vortex type impellers can transfer solids without issue.
Nappy wipes are a common issue with centrifugal pumps which should not be flushed, and we recommend positive displacement pumps such as our peristaltic pumps or progressing cavity pumps in areas where items being flushed into toilets can be difficult to control. Example areas where this occurs are primarily public toilets in locations such as hospitals, trains, shopping centres. Dry mounted sewage pumps are much cleaner and easier to service and we recommend these over submersible pumps due to the motor being located out of the fluid and thus being easier to inspect.
