Classification of pumps and applications
What are the application of pump?
Applications of pumps
- Pumping water from the wells.
- Aquarium and pond filtering.
- Water cooling and fuel injection in automobiles.
- Pumping oil or gas and operating cooling towers in energy industry.
- They also have their uses in waste water recycling, pulp and paper, chemical industry etc.
What are the 2 main classification of pumps?
Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).
What is pump What are different types of pumps explain in brief?
Centrifugal Pumps
| SUB-TYPE | DESCRIPTION | PERFORMANCE |
|---|---|---|
| Axial Flow Pump | Also known as a propeller pump, it produces water flow along the impeller shaft direction. | High flow rate Low pressure |
| Radial Flow Pump | This pump type produces flow in a direction perpendicular to the shaft (90° angle). | Low flow rate High pressure |

What are the applications of centrifugal pump?
Centrifugal pumps are commonly used for pumping water, solvents, organics, oils, acids, bases and any ‘thin’ liquids in both industrial, agricultural and domestic applications. In fact, there is a design of centrifugal pump suitable for virtually any application involving low viscosity fluids.
What is the classification of pump?
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 principle of pump?
The basic principle of operation of centrifugal pumps is – force vortex flow. This means, when a body of liquid is acted upon by an external torque, it increases the pressure head of the rotating liquid. This increase in pressure is directly proportional to the velocity of the liquid.
What is axial pump used for?
axial pump. Axial pumps are used for the promotion of incompressible fluids and are employed for large volume flows at relatively low delivery heads. As with all types of centrifugal pumps, the energy transmission in axial flow pumps is carried out exclusively through flow-related processes.
Which pump is used for high pressure?
Multi-stage centrifugal pumps tend to be used for applications that require higher pressure or pressure head. Diaphragm type pumps are generally deployed within the following ranges: Flow rate ranges between 20 to 750,000 lpm.
Which of the two classifications of pumps is the least efficient?
Each type of pump has its own advantages and disadvantages. Impulse pumps are the most efficient because they use less energy than displacement or volumetric pumps. Displacement pumps are the least efficient because they require more energy to move the same amount of fluid.
What are the 2 types of rotary piston positive displacement pump?
The simplest example of a rotary positive displacement pump is the gear pump. There are two basic designs of gear pump: external and internal (Figure 2). An external gear pump consists of two interlocking gears supported by separate shafts (one or both of these shafts may be driven).
What are the 3 types of centrifugal pumps?
Single-stage, Two-stage, or Multi-stage.
Which among the classification of pumps does single and double acting pump belong?
The first group of pumps includes: rotary and reciprocating pumps. The latter are divided into double-acting and single-acting reciprocating pumps, which in turn can be diaphragm or piston/plunger pumps.
Which pump is used for high pressure?
Multi-stage centrifugal pumps tend to be used for applications that require higher pressure or pressure head. Diaphragm type pumps are generally deployed within the following ranges: Flow rate ranges between 20 to 750,000 lpm.
What is axial pump used for?
axial pump. Axial pumps are used for the promotion of incompressible fluids and are employed for large volume flows at relatively low delivery heads. As with all types of centrifugal pumps, the energy transmission in axial flow pumps is carried out exclusively through flow-related processes.
What pump is used for water?
The two most common types of pumps used for pumping water are centrifugal pumps and positive displacement pumps.
Which pump is more efficient?
Where different pump designs could be used, the centrifugal pump is generally the most economical followed by rotary and reciprocating pumps. Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs.
Which type of pump is used in house?
There are four primary types of pumps. There are 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 sump pumps.
