Here are some more information for Centrifugal Pump:
A submersible pump is one that has a sealed motor, fitted in a pump body. The total assembly is immersed in the fluid that needs to be pumped. The main advantage of this type of pump is that it can offer a considerable amount of lifting power, as it does not rely on external air pressure.
A submersible pump has a system of mechanical seals that is used to prevent the fluid being pumped from entering the motor, resulting in a short circuit. A pump can either be attached to a pipe or a flexible hose.
Some of the types of submersible pumps are bladder pumps, bilge and ballast pumps, borehole pumps, booster pumps, and centrifugal pumps. Other examples are condensate pumps, dewatering pumps, fountain pumps, grinder pumps, micro pumps, sampling pumps, trash pumps, utility pumps, and well pumps. Some submersible pumps are manufactured for particular applications. These pumps are water submersible pumps, sewage submersible pumps, 12-volt submersible pumps, sand submersible pumps, irrigation submersible pumps, and solar submersible pumps. Solar submersible pumps have many uses and are suitable for slow and steady water transfer into a holding tank.
Submersible pumps are found in many appliances. Single stage pumps are utilized for drainage, sewage pumping, common industrial pumping, and slurry pumping. Multiple stage submersible pumps are normally used for water abstraction. These pumps can also be found in oil wells. Moreover, submersible pumps can be positioned directly in a pond and require comparatively little installation. These pumps are also relatively silent.
The four main specifications that should be considered while choosing a submersible pump are maximum expulsion flow, maximum discharge pressure, horsepower, and discharge size.
Earlier, the main drawback of submersible pumps was that its pump seal could rupture and release oil coolant into the water. However, newer pumps are magnet-driven, and no longer require a coolant. These magnet-driven pumps are more expensive, but they consume less electricity.

Keep your Engine Cool With a First Rate Water Pump
Your engine is an intricate machine that utilizes fuel and air through a process called combustion. This process allows a car to be able to run. Physics serves to remind any critical-thinking driver that any machine which undergoes a process of utilizing energy through combustion would involve heat. It is that very heat from the combustion of gasoline and air that car owners should look out for. This is why a car has a built-in cooling system which serves to regulate the heat that may build up inside the engine. The cooling system has many parts including the radiator, cooling fan, timing belt, heater hoses, engine block, cylinder head and water pump. All seven car parts work to ensure the proper regulation of temperature in the engine. All parts must be in proper working condition to make for an efficient circulation of coolant in the engine.
Among the parts previously mentioned, the water pump works as the heart of the cooling system. The water pump is usually a centrifugal pump that circulates coolant while the engine is running. It helps remove excessive heat from the engine. The water pump first receives hot, “used up” water from the radiator into the pump vanes. Hot water is then cooled and then circulated through the engine block and back into the radiator.
Most of the time, a car overheats because of a malfunctioning water pump. Among the telltale signs of a malfunctioning water pump is excessive noise while the car engine is running. Another is a coolant leak in the vent under the water pump. It is suggested that the water pump be replaced regularly as a preventive maintenance measure and that the replacement be secured in place whenever other parts of the cooling system are replaced as well. Having the pump replaced with everything else is a good option because there is better visibility for servicing the water pump when the rest of the parts in a cooling system are also removed for repair. A perfectly functioning water pump is important because it will save a car from the costly repairs of engine overheating. Make sure to purchase only high – quality water pumps that are worth every penny spent.

what is the meaning of curve of performance in centrifugal pump and positive displacement pump?
i not understand about curve of performance.... can anyone describe about it?
On a graph of pressure vs. discharge, Positive Displacement Pumps (PDPs) will be nearly a vertical line for any given discharge. In other words, they can have extremely high pressures at a given discharge.
Dynamic pumps (of which centrifugal is a type) vary. Generally, as their discharge increases, their pressure decreases.
