What is pump and its types PDF?
A pump is a device used to move fluids, such as liquids, gases or slurries.
A pump displaces a volume by physical or mechanical action.
Pumps fall into three major groups: direct lift, displacement, and gravity pumps.[ 1] Their names describe the method for moving a fluid..
What are mechanical pumps?
In mechanical pumps, the gas present in a vacuum system is transferred from a low pressure to a higher pressure region. In order to be efficient, the pump has to provide simultaneously a finite pumping speed and compression.
Which pump is used in homes?
There are four primary types: sump pumps, sewage pumps, utility pumps and well pumps. Sump pumps remove water that collects in basins from around a home’s foundation. Many are submersible pumps that have a manual or semi-automatic motor housed in a water-tight compartment so the pump can be fully immersed in liquid.
What is pump and its type?
Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
What is the difference between motor and pump?
Difference between Pump and Motor The main difference between motor and pump is that a motor is a device that converts electricity to mechanical energy which results in motion, whereas a pump is a device that is used to transfer a fluid from one place to another.
What are the different types of centrifugal pumps?

What are the two main types of water pumps?
Water pumps are mechanical or electromechanical devices that are designed to move water through pipes or hoses by creating a pressure differential. The two most common types of pumps used for pumping water are centrifugal pumps and positive displacement pumps.
What is the working principle of centrifugal pump?
A centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. The two main parts that are responsible for the conversion of energy are the impeller and the casing. The impeller is the rotating part of the pump and the casing is the airtight passage which surrounds the impeller.
What type of pump is a centrifugal pump?
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.
Which pump is more efficient?
In general, a reciprocating pump is more efficient than a centrifugal pump. Reciprocating machines are generally applied on low-flow/high-head service. Centrifugal pumps can have efficiencies as low as 40 percent on low-flow/high-head service.
What is pump duty?
Defined as that Duty Point on the H-Q curve where a centrifugal pump operates at maximum efficiency. It is determined by the Flow Rate and the Total Head at the respective pump speed.
How many types of water pumps are there?
twoThere are two basic types of water pumps: centrifugal and positive displacement. Both types are designed to move water from one place to another continuously. A centrifugal water pump uses a rotating impeller to move water into the pump and pressurize the discharge flow.
