Pumping stations house pumps to move fluids from one location to another. They have dedicated functions, such as pumping water from a reservoir or transporting waste. Two main types of pumps are rotodynamic and positive displacement, and modern pump stations are monitored by computer.
Pumping stations are buildings or locations that house pumps or other equipment designed to move water and other fluids from one location to another. Pumping stations are sometimes called lift stations. The particular type of equipment that resides in a specific pumping station will depend on its exact function and the type of fluid it requires to be pumped. You may need different pumps, for example, in a wastewater pumping station dealing with sludge and sewage, versus a water pumping station.
Pumping stations typically have a dedicated function. Many pumping stations form important structural parts of the public water supply system, typically serving to pump water from a reservoir and into a pipe system. Some pumping stations transport domestic sludge, liquid industrial waste or agricultural slurry. Other uses of pumping stations include managing the water supply of canals, pumping water uphill in some types of hydroelectric systems, irrigating farmland, and draining water from low-lying land.
The pumps used at these stations include two main types. These are rotodynamic pumps and positive displacement pumps and are classified by the mechanism they use to move fluids. Rotodynamic pumps work by adding pressure to a column of fluid to increase the rate at which fluid moves through a pipe.
A rotor pump uses a rotor to apply pressure to a fluid. These pumps are often called centrifugal pumps and can be used in a wastewater pumping station, as they enable thick sludge to be pumped. Centrifugal pumps are also often used in water pumping stations that supply water to agricultural irrigation systems.
Displacement pumps work by forcibly moving a quantity of fluid from an inlet tube to an outlet tube. These pumps usually produce a constant flow. As such, these pumps are often part of the equipment for a standard water pumping station that provides flow for a public water supply.
Modern pump stations are often monitored and maintained using a computer called a pump station manager. These computers offer the advantage of allowing a pumping station to run continuously, without necessarily being manned at all hours of the day or night. Pump station operator computers usually have an intuitive interface that allows non-technical personnel to operate the station. These computers typically monitor many important variables that affect how well pumping stations operate, such as liquid pressure and flow rates.
