Water supply pump design.

C equipment for wells. 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. The drivers will be constant speed ac motors of the squirrel cage induction wound rotor or synchronous type. They have an impeller which rotates in a casing of a special shape.

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. 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. For more details on the construction of jet pumps see this article. The hydraulics notions useful to design water supply system.

Pump design 1 2centrifugal pumps centrifugal or rotodynamic pumps are based on the principle of imparting kinetic energy to the water. Suction connection pipe 4. Water intake structure 2. Thus japanese products will be compared to eu products.

Remember that you must also take into consideration the level of the water in the suction tank. Which supply water to the distribution system wil l sub ject to flooding. In these pumps water enters axially and is discharged by the rotor into a discharge pipe. This may occur in irrigation or water supply projects.

Pump drives for water supply and distribution pumps will be electric motors. Stand by generator and its fuel tank 7. Drives for fire pumps will be in accordance with nfpa 20. Duration of the training 15 to 30 hours generality about this course this course is the first part of the design of water supply system methodology.

How much static head is required to pump water up from the ground floor to the second floor or 15 feet up. Major planning factors are. Lecture 6 design of waster supply pumping stations 6 5 surface water pumping stations 1. If the water level is 10 feet below the pump suction connection then the static head will be 10 15 25 feet.

Submersible or dry pumps connected in parallel 3. In either case gravity systems tend to involve high capital costs but low operating costs. Diesel or other fuels will be considered as a power source only for emergency use.
