Various Manufacturers provide a variety of Centrifugal pumps for different industry needs. Axially and radially split single casing are illustrated in Figures 8 and 9 respectively. The nozzle configuration can be of end suction top discharge, top suction top discharge, or side suction side discharge. A centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. The two main parts that are responsible for the conversion of energy are the impeller and the casing. 18. The input power of centrifugal pump is the mechanical energy and such as electrical motor of the drive shaft driven by the prime mover or small engine. A few leading examples of the manufacturer are Sulzer, Flowserve, Bingham, ITT, Goulds, SPX, National, Godwin, Aurora, Weir and Ebara. In a radial flow pump, the liquid enters at the center of the impeller and is directed out along the impeller blades in a direction at right angles to the pump shaft. Usually suitable for direct coupling to an electric motor. When provided, we may use your personal information to provide the best service possible. The disadvantage of this type is the difficulty in maintaining a seal at the joint when at higher pressures. Internal channels in the pump casing route the discharge of one impeller to the suction of another impeller. The water goes from the volute surrounding the discharge of one impeller to the suction of the next impeller. An impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped. This document describes the guidelines, privacy, terms, and conditions that we hold for our website users. External Websites A centrifugal pump with a single impeller that can develop a differential pressure of more than 150 psid between the suction and the discharge is difficult and costly to design and construct. Picture shows a diagram of the arrangement of the impellers of a five-stage horizontal pump and ten stage vertical multistage pump.

The following chief factors affect the performance of a centrifugal pump and need to be considered while choosing a centrifugal pump: Owing to the use in the diverse range of applications, pumps come with different capacities and in various sizes. The impeller of a radial flow centrifugal pump was developed with different blade generation method and it was concluded that concentric circular arc method is the most simple method to generate a blade profile [6]. We stock an assortment of centrifugal pumps of all types and sizes, and can custom design and build pumps and packaged pump systems for your specific needs. We may collect publicly available information, but do not collect personally identifiable information unless you specifically provide it. Impellers of pumps are classified based on the number of points that the liquid can enter the impeller and also on the amount of webbing between the impeller blades. The impeller is the rotating part of the pump and the casing is the airtight passage which surrounds the impeller. Centrifugal Pump Classification by Number of stages. In addition, by using our website under a registered business IP address, you give consent for Power Zone to contact the company under which your IP address is registered. In simple words, the pump head is pressure defined as the height to which the pump can raise the fluid to. Power Zone Equipment will only collect your personally identifiable information when you voluntarily provided it. Generally centrifugal fans have three types of blade: forward blade, backward blade and radial blade. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. Centrifugal pumps are used to induce flow or raise a liquid from a low level to a high level. Or send your question to: 1. It is mounded on the shaft which is coupled to an external source of energy which imparts the liquid energy to the impeller there by making it to rotate. Advertising Impellers can be either single suction or double-suction. Contact Us or Read Privacy Policy. The result indicates that both of head and efficiency are getting lower with the increase of blade thickness. Main Parts of Centrifugal Pump. A centrifugal pump acts as a reversed turbine except that in this device special modifications are made to increase the efficiency. It is available in a vertical column and end suction configuration. A double-suction impeller allows liquid to enter the center of the impeller blades from both sides simultaneously. • according to the design of the impeller; and The information that we collect is used to help improve our site and its functions.

Centrifugal pumps are classified in several ways. A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. The blades generally have a double backwards curve and a predominantly radial movement and are completely closed between the hub disc and the crown disc.

The water enters the pump from the top left and passes through each of the four impellers in series, going from left to right. Your privacy on the internet is important to us.   Â, Leading Manufacturers of Centrifugal Pumps. The impeller of a centrifugal pump can be of three basic types: Bearing support is also often used to categorize Centrifugal Pump: Shaft orientation is another characteristic which distinguishes the type of Centrifugal pump: The following highlights the difference between the above two: A good quality pump with superior components ensures efficiency and durability.
