A pump is a mechanical device that is used for transferring different fluids from one point to another. It is called a hydraulic device that increases the fluid level from low to high and then shifts from a low-pressure area to a high-pressure area. Pumps easily transfer fluids by converting the mechanical energy of the fluid into pressure energy. There are different types of pumps, and each has its features and uses. Here we will cover different types and their detailed features. So let’s get started with.
Types of Pumps
Centrifugal Pumps
- This type of pump is commonly used for different applications. This pump is easy to operate and effective with a low-cost design.
- If the pump is operating, fluid pressure increases from the inlet of the pump to the outlet. Change in pressure moves fluid through the system.
- This pump provides high force by transferring the mechanical power of the motor to fluid through a rotating impeller.
- The fluid flow goes to the middle of the impeller and comes out with vanes.
- Fluid velocity increases with centrifugal forces, and kinetic energy is also converted into force.
- Based on water flow generated by centrifugal pumps, there are some further types.
- Axial Flow Pump
- Radial Flow Pump
- Mixed Flow Pump
Vertical Centrifugal Pumps
- This type of pump is also called a cantilever pump. These pumps employ a certain type of shaft and retain a design that controls volume to the pit since bearings are on the external side of the pit.
- This pump is not operated with a filled container for covering the shaft; for that purpose, it uses a throttle bushing.
Horizontal centrifugal pumps
- This pump has two more impellers. These pumps are employed for pumping operations. Each step is a manifold pump.
- All parts are in the same bunkers and confined on the same shaft also. There are 8 more phases configured on certain horizontal shafts.
- Every phase provides heat through equal amounts. The multiphase pump is also a single-stage pump or double-suction pump.
- Different pumps are used for each type of centrifugal pump.
Diaphragm Pumps
- AOD pump is another name for diaphragm pumps and is also called pneumatic and AODD pumps. These pumps are used for different applications like general plant, also part of industries and mining.
- AOD pumps are used to provide power and are also part of the combustible area. It is also used for chemical transferring, industrial wastewater, and underground coal mines.
- It is the response pump that comes with two diaphragms operated with condensing air.
- The air part of the transfer valve provides air to both diaphragms, and the diaphragm comes with check valves.
Gear Pumps
- It is a rotating positive displacement pump that produces steady fluid as a result of every revolution. Pumps move fluid through the inside and outside of machines in a system of non-exciting pumping processes.
- This pump has features of pumping at high pressures and helps to easily pump concentrated fluids.
- Gear pumps do not come with valves that cause of losses like friction and high impeller speeds.
- So, pumps are good to handle thick fluids like greases and fuels.
Peristaltic pumps
- Other names of these pumps are tube pumps and peristaltic dosing pumps. It is a volumetric pump used for chemical processing, food, and water treatment in industries.
- It has a steady flow for mixing and measuring and can easily pump different liquids like toothpaste.
Lobe Pumps
- It is known as rotor pumps and comes with features like high efficiency, resistance, and reliable operation. It easily handles highly concentrated fluids and solids.
- It is operated with gear pumps, leaving vanes that do not connect.
- These pumps come with better pumping chambers than gear pumps which cause slurry to move.
Hydraulic Pumps
- This pump transforms mechanical energy into hydraulic energy. The working of this pump is based on Pascal’s law, and it can be seen in different applications, such as those used for agricultural equipment.
Jet Pumps
- It uses jet propulsion for moving fluid in the piping system. It is a self-priming pump that does not have a moving component. Friction losses occur in this pump that makes it less efficient than centrifugal pumps. This pump is used for larger water treatment systems.
Lobe Pumps
- It uses two or more rotating lobes for fluid displacement. Its main features are reliability and effectiveness. So it is used for the food industry.
Magnetic Drive Pumps
- It uses agents for fluid movement through an attraction and repulsion system. They are leakproof and have high efficiency. Their uses are in chemical industries and also in medical devices for handling dangerous fluids.
