Description
Overview of Centrifugal Pumps
Centrifugal pumps are to transfer fluids through an increase in pressure. Sino Mechanical centrifugal pumps have a simple design that produces high efficiency to hande a diverse range of head and capacity while producing a high flow rate.
Features of Centrifugal Pumps
1. Centrifugal pumps are usually specified for higher flows and for pumping lower viscosity liquids, down to 0.1 cP.
2. The efficient operation of a centrifugal pump relies on the constant, high speed rotation of its impeller.
3. Centrifugal pump designs offer simple and low cost solutions to most low pressure, high capacity pumping applications involving low viscosity fluids such as water, solvents, chemicals and light oils. Typical applications involve water supply and circulation, irrigation, and the transfer of chemicals in petrochemical plants.
4. Centrifugal pumps are the most common type of pump used in industry, agriculture, municipal (water and wastewater plants), power generation plants, petroleum and many other industries.
5. Centrifugal Pumps are highly versatile. They are available in many different shapes and sizes to handle a wide variety of installations and requirements, whether you need your pump to be driven electrically or magnetically, to self-prime, to be able to handle sanitary fluids or to be big enough for large industrial applications, there is a centrifugal pump solution available.
6. An additional key feature of a centrifugal pump is that it can be easily modified to suit different requirements for the end-user. For example, accessories can be used such as heating jackets, self-priming chambers and hygienic shrouds to achieve the perfect pump solution.
Applications of Centrifugal Pumps
Applicable Medium of Centrifugal Pumps : Clean water, sewage, sea water, petroleum, gasoline, diesel, heavy oil, LPG, chemical liquid, etc.
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 are the Advantages of Centrifugal Pumps?
1. Smooth Flow – Centrifugal flow is laminar and non-pulsating allowing them to be used with flowmeters easily.
2. Low Maintenance & Easy to maintain - Due to their simple uncomplicated design, which are often maintained without special tools or equipment.
3. Efficient – As the internal elements are free to rotate, they are very efficient when handling low viscosity fluids
4. Versatile – They can be designed to handle a multitude of liquids and solids by changing the materials of certain parts, or impeller design.
5. Low Cost – Due to their simplicity of design and wide availability, they are one of the lowest initial costs of pump. If specified correctly they can also provide the lowest lifetime cost for an application.
6. Low Infrastructure costs – As Centrifugal pumps can be ran against a closed valve for short periods without damage, additional accessories such as pressure relief valves and other devices are not required.

Specification
Technical Specifications of Centrifugal Pumps
1. Flow rate - the amount of liquid (volume or mass) flowing through a certain section per unit time. Expressed with Q. The units are: m3/h, m3/s, l/min.
2. Head - the increase in energy per unit mass of liquid being transported from the pump inlet to the outlet. Represented by H. The unit is: MPa, m.
3. Speed - the number of revolutions of the shaft per unit time. Use n to represent. The unit is: r/min.
4. Equipped power - the rated power of the prime mover. Represented by N. The unit is: kW.5. Shaft power - the power transmitted from the prime mover to the pump shaft. Expressed with P. The unit is: kW.
6. Effective power - also known as output power, the effective energy obtained in the pump by the liquid delivered from the pump per unit time. Expressed in Pa. The unit is: kW.
7. Efficiency - the ratio of effective power to shaft power. Expressed with n.
9. NPSH - the excess energy (expressed in meters of liquid column) of the unit mass of liquid at the suction inlet of the pump exceeding the vaporization pressure of the liquid. Expressed in NPSH. The unit is: m.
10. Necessary NPSH - the NPSH determined according to the test (measured in meters of liquid column). Expressed in NPSHr. The unit is: m. The pump NPSH is determined by the characteristics of the pump itself, and is a parameter indicating the anti-cavitation performance of the pump itself. In order to improve the anti-cavitation performance of the pump itself, the NPSH must be reduced as much as possible.
