Water Pumping Station<\/strong><\/h2>\n
Pumping stations are necessary to transport water where there is an insufficient head. The capital cost of pumping station is high, but the most expensive part is the energy supply for pumps (mostly electrical). Therefore, it is very important that pumping station design have a high degree of efficiency and are maintained properly. The pumping station consists of water intake structures for suction pipes of pumps, the pumps themselves, motor, gear from motors to the pumps, pressure pipeline transporting water from the pumps to the water-discharge device, etc. Thus, the conception of a pumping installation includes all the components of the operation depends on the pump performance.<\/p>\n
