Water Supply Pump Design

Why ensure a basic and common understanding of the necessary theory to design water supply system.

Water supply pump design.

The hydraulics notions useful to design water supply system. The system in figure 2 is a typical domestic water supply system that takes it s water from a shallow well 25 feet down max using an end suction centrifugal pump. Pump drives for water supply and distribution pumps will be electric motors. 3 0 water pumping systems design 3 1 pump fed vs gravity water supply water pumping is required in situations where site conditions do not favour the use of gravity supply.

Main electricity distribution panel and control 8. Suction connection pipe 4. Diesel or other fuels will be considered as a power source only for emergency use. Submersible or dry pumps connected in parallel 3.

In either case gravity systems tend to involve high capital costs but low operating costs. Water intake structure 2. The drivers will be constant speed ac motors of the squirrel cage induction wound rotor or synchronous type. Be loc ated near the water treatment facility or a availability of electric power roadway access fo r potable water storage facility and wi ll pump directly mainten ance and operation purposes security and into the piping system.

Figure 2a typical jet pump. C equipment for wells. Pump design 1 2centrifugal pumps centrifugal or rotodynamic pumps are based on the principle of imparting kinetic energy to the water. In these pumps water enters axially and is discharged by the rotor into a discharge pipe.

How much static head is required to pump water up from the ground floor to the second floor or 15 feet up. Lecture 6 design of waster supply pumping stations 6 5 surface water pumping stations 1. Drives for fire pumps will be in accordance with nfpa 20. They have an impeller which rotates in a casing of a special shape.

Basic design study on the project for zanzibar urban water supply development in tanzania final report 2 60 b equipment for transmission pump station the existing transmission pumps are made in eu which are regarded as reliable serviceable and economical. Remember that you must also take into consideration the level of the water in the suction tank. Thus japanese products will be compared to eu products. For more details on the construction of jet pumps see this article.

Which supply water to the distribution system wil l sub ject to flooding. Stand by generator and its fuel tank 7. This may occur in irrigation or water supply projects.
