i) Centrifugal Pumps: Centrifugal pumps are used in buildings for pumping the general water supply, as a booster and for domestic water supplies. The design of a centrifugal pump makes them useful for pumping sewage and slurries. They are also used in fire protection systems and for heating and cooling applications. 

Reason: It is a low head high discharge pump 

ii) Jet pumps can be used for either oil wells, bore wells (lesser depth), deep or shallow well applications. Mini. jet pumps are used for smaller applications, such as aquariums. 

Reason: It is a medium head and high pressure pump 

iii) Submersible Pumps: Multiple stage submersible pumps are typically lowered down a borehole and most typically used for residential, commercial, municipal and industrial water extraction (abstraction), water wells and in oil wells. Other uses for submersible pumps include sewage treatment plants, seawater handling, fire fighting (since it is flame retardant cable), water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, and irrigation systems. 

Reason: It is a high head and high pressure pump & there are no cavitations. It has high efficiency at high heads.
