Types of Pumps
There are many types of industrial pumps offered for a variety of applications. Each type of industrial pump comes with advantages not offered by other pumps.
Types of Pumps
Pumps are classified into two types namely Dynamic pumps as well as Positive Displacement Pumps.
Dynamic Pumps
Dynamic pumps are classified into different types but some of them are discussed below like Centrifugal, Vertical centrifugal, Horizontal centrifugal, Submersible, and Fire hydrant systems.
1). Centrifugal Pumps
The best choice for lower viscosity liquids and high flow rates.
These types of pumps are most used worldwide. The working is amazingly simple, described well and carefully tested. This pump is strong, efficient, and cheap to make. Whenever the pump is in action, then the fluid pressure will increase from the inlet of the pump to its outlet. The change of pressure will drive the liquid throughout the system.
This kind of pump produces an enhancement within force by transmitting mechanical power from the electrical motor to the liquid throughout the revolving impeller. The flow of liquid will enter the center of impeller and exits along with its blades. The centrifugal power hereby enhances the velocity of fluid & also the energy like kinetic can be altered to force.
2). Vertical Centrifugal Pumps
Vertical centrifugal pumps are also called as cantilever pumps. These pumps use an exclusive shaft & maintain design that permits the volume to fall within the pit as the bearings are external to the pit. This mode of pump utilizes no filling container to cover the shaft however in its place uses a throttle bushing. A parts washer is the common application of this kind of pump.
3). Horizontal Centrifugal Pumps
These types of pumps include a minimum of two otherwise more impellers. These pumps are utilized in pumping services. Every stage is fundamentally a divide pump.
All the phases are in a similar shelter & mounted on a similar shaft. On a solo horizontal shaft, minimum eight otherwise additional stages can be mounted. Every stage enhances the head by around an equal amount. Multi-stage pumps can also be single otherwise double suction on the first impeller. All kinds of pumps have been providing as well as servicing this type of centrifugal pumps.
4). Submersible Pumps
These pumps are also named as storm water, sewage, and septic pumps.
The applications of these pumps mainly include building services, domestic, industrial, commercial, rural, municipal, & rainwater recycle applications.
These pumps are apt for shifting storm water, subsoil water, sewage, black water, grey water, rainwater, trade waste, chemicals, bore water, and foodstuffs. The applications of these pipes mainly include in different impellers like closed, contra-block, vortex, multi-stage, single channel, cutter, otherwise grinder pumps. For different applications, there is an extensive selection is accessible which includes high flow, low flow, low head, otherwise high head.
Positive Displacement Pumps
Positive displacement pumps are classified into different types but some of them are discussed below like diaphragm, gear, peristaltic, lobe, and piston pumps.
1). Diaphragm Pumps
One of the most versatile choices handling a wide range of liquids that are seal less and can run dry without damage to the pump.
Diaphragm pumps also known as AOD pumps (Air operated diaphragms), pneumatic, and AODD pumps. The applications of these pumps mainly include in continuous applications like in general plants, industrial and mining. AOD pumps are particularly employed where power is not obtainable, otherwise in unstable and combustible regions. These pumps are also utilized for transferring chemical, food manufacturing, underground coal mines, etc.
these pumps are responding pumps and include two diaphragms which are driven with condensed air. The section of air by transfer valve applies air alternately toward the two diaphragms, where every diaphragm contains a set of ball or check valves.
2). Gear Pumps
The best choice for clean oil applications with few moving parts & simple constructions.
These pumps are a kind of rotating positive dislocation pump, which means they force a stable amount of liquid for every revolution. These pumps move liquid with machinery coming inside and outside of mesh for making a non-exciting pumping act. These pumps are capable of pumping on high forces & surpass at pumping high thickness fluids efficiently.
A gear pump does not contain any valves to cause losses like friction & also high impeller velocities. So, this pump is compatible for handling thick liquids like fuel as well as grease oils. These pumps are not suitable for driving solids as well as harsh liquids.
3). Peristaltic Pumps
Peristaltic pumps are also named as tube pumps, peristaltic pumps. These are a kind of positive displacement pumps and the applications of these pumps mainly involve in processing of chemical, food, and water treatment industries. It makes a stable flow for measuring & blending and capable of pumping a variety of liquids like toothpaste and all kinds of chemicals.
4). Lobe Pumps
The best choice for sanitary applications that pump viscous liquids or liquids that contain fragile solids, featuring no metal-to-metal contact within the pump.
These pumps offer different characteristics like an excellent high efficiency, rust resistance, hygienic qualities, reliability, etc. These pumps can handle high thickness fluids & solids without hurting them. The working of these pumps can be related to gear pumps, apart from the lobes which do not approach into contact by each other. Additionally, these pumps have superior pumping rooms compare with gear pumps that allow them to move slurries. These are made with stainless steel as well as extremely polished.
5). Piston Pumps
The best choice for applications that involve abrasive liquids.
Piston pumps are one kind type of positive dislocation pumps wherever the high force seal responds through the piston. These pumps are frequently used in water irrigation, scenarios requiring high, reliable pressure and delivery systems for transferring chocolate, pastry, paint, etc.
