Water supply systems usually need high pressures so as to pump water to longer distances. It is also possible for systems that have water moving in a cycle to lose the pressure after some time. In such cases, the system requires a booster pump that will supply the extra pressure. Water booster pumps are used for a variety of applications that are listed below.
Where the System Covers a Large Geographical Location
A working system of water supply makes use of pipes, valves and gates to direct water to a given location. The pipes along which the water flows contain friction which tends to act in opposing the water flow. The amount of frictional force experienced directional to the length of the system piping. The implication is that there’s a significant reduction in the pressure of the water. Thus the system will need a boost of pressure if it’s expected to deliver the water at the point of utilization. Booster pumps are normally installed at certain intervals on a long distance pipeline to provide the necessary boost of pressure.
Pumping Form Deep Wells
Sometimes it is necessary to pump water from wells that are very deep. This is especially the case where the wells are dug in relatively dry and semi-arid areas where the water levels are usually very low. The system installed over such a well will require very high pressure to draw water against gravity. And due to the fact that there may not be sufficient pressure in one pump to accomplish the task, the system will require incorporation of booster pumps along its length to supplement the primary pumps.
Pumping System with a Varied Load
Municipal water supply systems have to deal with varying demands for water from their clients. This is occasioned by the varied Water consumption rates for different people during the day. This gives rise to peak demand hours as well as off-peak hours where the demand peaks. The supplying company would go at a loss if they attempted to base the system design on peak consumption rates. The best approach to ensure optimum operation would be to install a system that can comfortably handle off-peak supply, then have a system of booster pumps to take care of the peak hours. Irrespective of the conditions during operation, such a system can handle the varied loads perfectly.
Pumping and Disposal of Sewage Waste.
There usually exists constant fluctuation in the viscosity of sewage waste handled by the municipal waste management. The higher the viscosity, the higher the pressure required to drive the waste so as to avoid clogging of the system. The system will therefore need to be designed with the normal flow in mind, then a separate booster pump system put on standby for those instances when the flow will be extra thick.
