Submersible pumps are generally used in wastewater treatment plants in situations where gravity water flow is impossible. A high water table, rocky soil conditions, or a long pipe running through a hilly area are examples of environments where flow by gravity is impossible. In such cases, a below-grade basin collecting wastewater and pumps it to a higher elevation is generally used.
This is known as a lift station or a pump station. A submersible pump is often used in lift stations because it costs less to install and it is compact than other pump options. The pumps don’t obstruct vision. They are almost silent when operating and this is a plus. A submersible water pump is very dependable in tough environments. The pumps are made of sturdy iron castings. The iron castings are protected by epoxy.
A top submersible pumps manufacturer should ensure that the pumps are achievable with long-life bearings, a special cord entry system and abrasive resistant mechanical seal created to protect the liquid from getting into the motor. Submersible water pumps motors remain cool during operation since the liquid enveloping the submersible water pump has a temperature below 100F. Fibre glass and concrete are the most common materials used in basins.
Unique and special rail systems simplify the
installation and removal process of submersible water pumps from the basin when
maintenance and servicing are necessary. Sensors connected to a control panel
direct the operation of the pump.
Submersible pumps are well protected by special features on the control panel located in a ventilated area outside the basin. Lift stations have two main types of submersible pumps used. Pumps that can handle solids in large systems are used when a high flow rate is required while small systems use grinder submersible water pumps. Properly designed stations for pumps are necessary because they are a good investment and are expensive to maintain.
