For pumping systems that need to supply water over long stretches of distance, high pressures are usually required. Similarly, cyclical water systems where water moves in a loop experience instances where the pressure in the system falls below a certain minimum value. This is where the idea of a booster pump system to supply the extra pressure comes in handy. Water booster pumps are used for a variety of applications that are listed below.
Pumping Water over Long Distances
A water supply system normally consists of water traveling along pipes and through gates and valves. The water in the pipes experiences frictional force that tends to oppose its flow. Frictional force is usually greatest if the water has a longer distance to cover along the pipes. In the end the pressure imparted on the water by the pump tends to drop after some time and distance. 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
In some cases, the water to be extracted is contained in very deep wells. Wells that are sunk in arid and semi-arid areas are usually of this nature. 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.
Systems with Varying Pumping Loads
Most water supply systems for the urban centers usually have to cope with a varied demand for water In the course of a single day, different people will require various amounts of water for their use. This gives rise to peak demand hours as well as off-peak hours where the demand peaks. Peak consumption rate is hardly the parameter to use when setting up a supply system since this would mean losses for the company. 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. This ensures that the systems appropriately handles the varying loads based on the demand.
Pumping and Disposal of Sewage Waste.
Municipal sewage waste also has varying degrees of viscosity. The amount of pressure necessary to drive the waste through the pipes changes with the viscosity of the waste, with the more viscous waste needing higher pressure and vice versa. To take care of the highly viscous flow, a booster pump will have to be installed to supplement the normal system.
