Water Supply Pump Design

Drives for fire pumps will be in accordance with nfpa 20.

Water supply pump design. 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. The drivers will be constant speed ac motors of the squirrel cage induction wound rotor or synchronous type. Figure 2a typical jet pump. 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.

In either case gravity systems tend to involve high capital costs but low operating costs. In these pumps water enters axially and is discharged by the rotor into a discharge pipe. Which supply water to the distribution system wil l sub ject to flooding. Stand by generator and its fuel tank 7.

Submersible or dry pumps connected in parallel 3. Thus japanese products will be compared to eu products. Suction connection pipe 4. 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.

They have an impeller which rotates in a casing of a special shape. Water intake structure 2. The hydraulics notions useful to design water supply system. Major planning factors are.

If the water level is 10 feet below the pump suction connection then the static head will be 10 15 25 feet. Remember that you must also take into consideration the level of the water in the suction tank. 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. For more details on the construction of jet pumps see this article.

Pump drives for water supply and distribution pumps will be electric motors. Main electricity distribution panel and control 8. Why ensure a basic and common understanding of the necessary theory to design water supply system. Lecture 6 design of waster supply pumping stations 6 5 surface water pumping stations 1.

C equipment for wells. How much static head is required to pump water up from the ground floor to the second floor or 15 feet up. Diesel or other fuels will be considered as a power source only for emergency use.
