What is Pump
A pump is a machine that pressurizes by some mechanism (usually a reciprocating or rotary type), transporting fluid from a low level (low pressure area) to a high level (high pressure area). Pumps can only transport substances with fluid as a medium, not solids. Fluids include water, oil, acid-base liquid, emulsion, suspoemulsion, liquid metal and other liquids, and can also transport gas. As a machine, a pump can be powered by a variety of energy sources. Such as physical operations, electricity, motors or wind. Meanwhile, pumps include a variety of sizes, from microscopic pumps to various large industrial pumps. Regardless of the size of the pump, all pumps deliver fluid from the pump's inlet to the pump's outlet by increasing pressure.The structure of the pump is also not complicated. For example, a centrifugal pump is mainly composed of a pump body, an impeller, a sealing ring, a rotating shaft, a shaft seal box and other components. Each part can be finished by casting process. Then assembled into a complete pump.

Types of Pump
Lorem ipsum dolor sit amet, consectetur adipiscing slit. Nunc blandit dui eget ipsum pulvinar tempor. In laoreet elit sodales, finibs lorem nec, rutrum ipsum.
multistage pump
These types of pumps are most commonly used worldwide. The working is very simple, described well and carefully tested. This pump is strong, efficient and fairly 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.
Double Suction Pump
As an important form of centrifugal pump, double suction pump has the characteristics of high head and large flow rate. The inlet and outlet of double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of pump and inlet and outlet pipes. The impeller structure of double suction pump is symmetrical, there is no axial force, and the operation is relatively stable. It is widely used in engineering, mainly for conveying clean water and liquids with physical and chemical properties similar to water.
Self-balancing multistage pump
The self-balancing multistage pump adopts an advanced hydraulic model and independently develops high-efficiency and energy-saving products. Through the symmetrical arrangement of impeller rotor components, the axial forces generated during operation offset each other and automatically balance, thus eliminating the need for traditional balancing discs or balancing drum structures. This design not only reduces friction loss and volume loss, but also improves overall efficiency, which is 3-5% higher than the average efficiency of ordinary multistage pumps.
Boiler Feed Pump
Boiler feed pump is a kind of equipment widely used in the power and thermal industry. Its working principle is to pressurize low-pressure water through the rotation of the impeller to make it reach a sufficiently high pressure to meet the needs of the boiler. It has the characteristics of wide performance range, high operating efficiency and long service life. It is particularly suitable for industrial boiler water supply and drainage, cooling water transportation, etc.
Pumps are basically simple devices that are used to move fluids by mechanical means. Pumps come in many different forms, but all share the common goal of moving fluid from one place to another. Pumps can be used for various applications based on need, including moving water, air, gasoline, and other liquids.
Pumps work by creating a vacuum which is used to push or pull liquids or gasses. Different types of pumps have different ways of working; however, what remains common is creating a difference in pressure points which creates suction. The liquid or the gas will always move from high to low pressure.
The type of pump you use will depend on the job you need it to do. For example, a small hand-held pump is typically used to inflate a tire, while a much larger pump is necessary to move water through a plumbing system. There are many different types of pumps, each with unique features and benefits.
The main performance parameters of the pump
The main performance parameters of the pump are flow rate, lift, shaft power, necessary NPSH, speed, etc.
The flow rate of the pump
The quantity of liquid provided by the pump per unit time, there is volume flow Q, the unit is m3/s; there is mass flow G, the unit is kg/s.
The lift of the pump
Lift is the energy increment per unit weight of the liquid transported from the pump inlet to the outlet. Usually expressed in H. The unit is m. Taking the water pump as an example, the lift of the water pump refers to the height at which the water pump can lift water.
The shaft power of the pump
Shaft power is a term often used on pumps. It refers to the work given to the pump shaft per unit time under a certain flow and head. It is represented by P and the unit is kW.
Speed
The number of revolutions per minute of the pump, represented by n, in r/min.
NPSH
The NPSH must be related to the internal flow of the pump, it is independent of the device parameters. It indicates the degree to which the pressure of the liquid drops in the inlet part of the pump. That is to say, in order to prevent cavitation of the pump, it is required that the unit weight of the liquid at the pump inlet has excess energy exceeding the vaporization pressure head.The smaller the required NPSH, the better the pump's cavitation resistance.
There is an interdependent relationship between the various performance parameters of the pump. And the viscosity of the liquid conveyed by the same pump is different. The relationship between its performance parameters will also change. For example, a power pump, as the viscosity of the liquid increases, the lift and efficiency of the power pump decrease, and the shaft power increases. It is also for this reason that in order to improve the conveying efficiency in the industry, the liquid with high viscosity will be heated to reduce the viscosity.
Pump Application Industries
Chemical industry
Most of the raw materials, finished products and semi-finished products of chemicals and petroleum are liquids and require complex technological processes. The main functions of pumps in the chemical industry are: transporting liquids, providing pressure flow for chemical reactions, and adjusting temperature.
Agriculture
In agriculture, a large number of pumps are required every year, which can account for more than 40% of the total pump production. These pumps are commonly used for irrigation and drainage in agriculture.
Mining
Pumps are also common equipment in the mining and metallurgical industries. It can supply water in the process of smelting and rolling. It can also drain mine.
Power industry
In the power system. Thermal power plants need a large number of pumps. Including water pumps, condensate pumps, and circulating water pumps. In nuclear power plants, nuclear main pumps, secondary pumps, tertiary pumps are needed.
Medical industry
Pumps can be used in pharmaceutical development and manufacturing processes. And can be used as artificial replacements for body parts. such as artificial hearts.
Energy industry
Pumps can be used to transport oil and gas. It can also be used in cooling towers, heating, ventilation and air conditioning systems.
Principles of Pump Selection
The selection of the pump type can be considered according to the performance parameters, the nature of the conveying fluid, the technological process, the water supply and drainage requirements and other factors. Performance parametersBefore selecting a pump, first consider the performance parameters of the pump. Including flow, head, temperature, cavitation flow, suction lift, etc.
Flow rate
Flow rate is one of the important performance data for pump selection. It is directly related to the delivery capacity of the pump. When choosing a pump, take the maximum flow as the basis and take into account the normal flow. If there is no maximum flow, 1.1 times the normal flow can be taken as the reference.
Pump lift
Pump lift is another important performance data for pump selection. Generally, it is necessary to enlarge the 5%-10% margin and then choose.
Conveying fluid properties
The properties of the transport fluid include physical properties, chemical properties and other properties. Physical properties include temperature, density, viscosity, and solid particle diameter and gas content in the fluid. Chemical properties include chemical corrosiveness, toxicity, and flammability and explosion of fluids.
The Size of the Pump
For the normal operation of the pump, generally only one large pump is used, and two small pumps are not selected.In the case of the same head and flow, a large pump is equal to two small pumps working in parallel, and the efficiency of the large pump is higher than that of the small pump, which can reduce the cost. If the flow rate is too large and one pump cannot reach this flow rate, two pumps can be considered for parallel cooperation. If the pump needs to run continuously for 24 hours, three pumps should be spared. One for operation, one for backup and one for maintenance.
he Shape of the Pump
Volute-shaped housing
The shell of this shape can be divided into single volute and double volute. The double volute structure consists of two volutes offset by 180° to balance radial forces.
Vortex housing (vortex volute)
The cross-section of the vortex casing is clearly asymmetrical on the meridian plane, reference can be made to the volute pump with mixed flow impeller and vortex volute.
Ring housing (ring housing)
The circumference of the annular casing has a constant cross-sectional area. Which can be referred to as a double-suction annular casing pump.
Elbow housing.
Elbow housing input flow is discharged into the elbow (housing) through a diffuser, see Elbow Housing Pumps.
How Do I Select the Right Pump for My Needs
Define the parameters of your application, including the type of fluid to be pumped, desired flow rate, required pressure, temperature considerations, and any unique characteristics of the fluid in question.
