There are various types of water pumps on the market. This article will help you understand the main functions of each type of pump. Our requirements primarily determine the type of pump and its selection. The application mostly involves the sort of fluid you want to pump, the distance you want to move the fluid, and the amount you need in a specific time frame. However, determining which type of water pump you need is difficult. You can identify the pump by its design and position. To simplify the search for the right pump, you can divide pumps into two types that function in very different ways and generally summarize most pump designs.
Types of water pumps
Pumps can be classified into two types namely Dynamic pumps as well as Positive Displacement Pumps.
1. Dynamic Pumps
A dynamic pump is a type of velocity pump that imparts kinetic energy to the fluid by increasing flow velocity. When the flow velocity is reduced before or as it exits the pump into the discharge pipe, the increase in energy is converted into a gain in potential energy (pressure). A dynamic pump is also known as a kinetic pump because it uses kinetic energy to pump the fluid. In this pump, the fluid is typically pumped by centrifugal force. Good examples for these pumps are the V- Guard pumps which you’ll find in a common household. Dynamic pumps are classified into different types like Centrifugal, Vertical centrifugal, Horizontal centrifugal, Submersible, and Fire hydrant systems.
A. Centrifugal Pumps
These are the most common types of water pumps used around the world. The operation is very simple, well described, and thoroughly tested. This pump is strong, efficient, and reasonably priced. When the pump is turned on, the fluid pressure increases from the pump’s inlet to its outlet. The pressure change will propel the liquid throughout the system.
This type of pump increases internal force by transmitting mechanical power from the electrical motor to the liquid via the revolving impeller. The flow of liquid enters the impeller’s centre and exits through its blades. The centrifugal force increases the velocity of the fluid, and the energy, such as kinetic energy, can be converted to force.
B. Vertical Centrifugal Pumps
Vertical centrifugal pumps are also known as cantilever pumps. Because the bearings are external to the pit, the volume of these pumps can fall within it. This type of pump does not use a filling container to cover the shaft, instead employing a throttle bushing. A common application for this type of pump is a parts washer.
C. Horizontal Centrifugal Pumps
These pumps have at least two impellers and possibly more. These pumps are used in the pumping industry. Each stage is essentially a divide pump. All phases share a similar shelter and are mounted on a similar shaft. A minimum of eight stages can be mounted on a single horizontal shaft; otherwise, additional stages can be mounted. Every stage improves the head by roughly the same amount. These pumps are typically used in businesses that transport large amounts of industrial fluids. This type of centrifugal pump has been provided and serviced by all types of pumps.
D. Submersible Pumps
These pumps are also known as stormwater, sewage, and septic pumps. They are primarily used in building services, domestic, industrial, commercial, rural, municipal, and rainwater recycle applications. These pumps are suitable for moving stormwater, subsoil water, sewage, black water, grey water, rainwater, trade waste, chemicals, bore water, and foodstuffs. These pipes are commonly used in impellers such as closed, contra-block, vortex, multi-stage, single channel, cutter, and grinder pumps. There is a large selection available for various applications, including high flow, low flow, low head, and otherwise high head.
E. Fire Hydrant Systems
Fire hydrant pump systems are also known as hydrant boosters, fire pumps, and fire water pumps. These are high force water pumps designed to increase the capacity of construction fire fighting by increasing the force within the hydrant service when mains are insufficient. This system’s main applications are irrigation and water transfer.
2. Positive Displacement Pumps
A Positive Displacement pump (PD pump) is a mechanical device that moves a known amount of liquid with each revolution or cycle of the pump. The flow rate of a positive displacement pump is proportional to its speed and the number of cycles performed in a given time. Positive displacement pumps are classified into different types like diaphragm, gear, peristaltic, lobe, and piston pumps.
A. Diaphragm Pumps
Diaphragm pumps are also known as AOD (Air operated diaphragm) pumps, pneumatic pumps, and AODD pumps. The primary use of these pumps is in continuous applications such as general plants, industrial, and mining. People primarily use AOD pumps in areas where power is unavailable, such as in unstable and combustible areas. People also use these pumps to transport chemicals, food, underground coal mines, and other materials. These pumps are responding pumps with two diaphragms that people power using compressed air. The air section by transfer valve alternately directs air towards the two diaphragms, each of which contains a set of ball or check valves.
B. Gear Pumps
These pumps are a type of rotating positive dislocation pump, meaning they force a constant amount of liquid with each revolution. The machinery moves inside and outside of the mesh for a boring pumping act in order to move the liquid. They are capable of pumping high forces and outperform at pumping thick fluids efficiently. A gear pump does not have any valves to cause losses such as friction or high impeller velocities. As a result, this pump is suitable for handling thick liquids such as fuel and grease oils. These pumps are not suitable for driving solids as well as harsh liquids.
C. Peristaltic Pumps
Peristaltic pumps are also known as tube pumps and peristaltic pumps. These are positive displacement pumps, and their main applications are in the chemical, food, and water treatment industries. It produces a consistent flow for measuring and blending and can pump a wide range of liquids, including toothpaste and various chemicals.
D. Lobe Pumps
These water pumps have various characteristics such as high efficiency, rust resistance, hygienic qualities, reliability, and so on. These pumps can handle thick fluids and solids without being damaged. Apart from the lobes that do not come into contact with each other, the operation of these pumps is similar to that of gear pumps. Furthermore, these pumps have larger pumping rooms than gear pumps, allowing them to move slurries. These are made of stainless steel and are highly polished.
E. Piston Pumps
Piston pumps are a type of positive dislocation pump in which the high force seal responds via the piston. People commonly use these pumps in water irrigation, scenarios that require high, dependable pressure, and delivery systems for transferring chocolate, pastry, paint, and other materials.
