A sewage pump plays a major role in sewage pumping. It is the most important device that is needed to pump sewage from sewer to sewage pumping station. The sewage pump acts as the main sewage handling equipment. In case of any sewage pumping station, there is only a single sewage pump that connects it to the sewage pipes. It consists of an engine-driven motor that works independently, while providing sewage lifting services as well.
A sewage pump works by using a membrane to trap solids and liquids on its external interface. The solids are then pumped out of the trap through the sewage pump's discharge pipe. Generally, in residential applications, sewage contains both soft and hard solids, typically up to 2 in length. Generally, a sewage pump is placed at the bottom of the sewage pit.
The working principle of a submersible sewage pump can be best understood by looking at the working principle of a surface-mounted sewage pump. This is similar to that of the common surface-mounted pumps that can be found in any metropolitan locations throughout the world. This pump works by trapping the wastewater and then making it move by way of a gravity force into the underground pipes. The water then flows through the pipes until it reaches a sewage treatment plant, where it is disposed of.
One of the most important components of this pumping machine is its impeller. The impeller functions as the housing for the mechanical parts of the sewage pump. The impeller structure includes one or more rotating shafts which, in turn, make the use of centrifugal force to spin the balls (in the case of a surface-mounted pump) or other materials (in the case of a submersible pump) in the housing. The rotation of the impeller shaft allows the wastewater particles to flow down the drainage pipe or discharge pipe and reach its destination.
The final component of any submersible sewage pump system is the pumping cylinder. Located inside the impeller housing, the pump cylinder fills the role of an inlet valve for the discharge pipe. In addition to the discharge valve, the pump can be connected to a stop valve (if necessary) or else it can operate mechanically. Most of these pumps are made with a screw threading on the inlet side for the purpose of permitting the threads to interlock with each other so that they can properly bind when the pipes are shut off.
A relatively flat region in the tank is called the head. The head curve of any submersible pump will vary depending upon the specific application. For example, if you are utilizing a relatively flat region inside the tank, the curve will be virtually horizontal. Conversely, the head curve will begin to flatten as the tank moves closer to the septic tank wall. You should also note that the type of septic tank and the type of sewage pump will both determine the curve as well as the diameter and height of the head curve. Submersible sewage pumps will typically have a similar head curve.
