Horizontal Multistage Centrifugal Pump

Horizontal multistage centrifugal pumps are one of the most popular types of pumps used in industry today. These pumps are able to move large volumes of fluid with a very high level of efficiency. The working principle behind these pumps is quite simple - they use centrifugal force to move the fluid through the pump. We're well-known as one of the leading end suction water pumps manufacturers and suppliers for our quality products and competitive price. Please feel free to buy bulk end suction water pumps for sale here from our China factory.

ShouFei Pump is one of the leaders of water pump manufacturers in China. All of the multistage pumps produced are CE certificated.Horizontal multistage centrifugal pumps with soft seal can be produced with mechanical seal optionally.

What is a horizontal centrifugal pump

Horizontal centrifugal water pump is one of the most widely used in refrigeration and air conditioning projects. It is characterized by relying on the high-speed rotation of the impeller to obtain greater kinetic energy for the fluid, and relying on the change of the volute section at the outlet of the flow passage to convert the kinetic energy of the fluid into pressure energy. The flow of water in the impeller is mainly affected by centrifugal force.


Horizontal centrifugal pumps are most widely used in chemical production because of their outstanding advantages, such as wide range of performance (including flow, pressure head and invincibility to medium properties), small size, simple structure, easy operation, uniform flow, less confusion, long life, low purchase and operation costs. 

Working principle of horizontal centrifugal pump

When the horizontal centrifugal pump is working, depending on the high-speed rotating impeller, the liquid obtains energy under the action of inertial centrifugal force to improve the pressure. Before the horizontal centrifugal pump works, the pump body and inlet pipeline must be filled with liquid medium to prevent cavitation.

When the impeller rotates rapidly, the blade makes the medium rotate quickly. The rotating medium flies out of the impeller under the centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. On the one hand, the liquid is continuously inhaled, and on the other hand, certain energy is continuously given to the inhaled liquid to discharge the liquid. The horizontal centrifugal pump works continuously. 

Horizontal centrifugal pumps are widely used in large quantities. In addition to industrial applications, they are also widely used in agricultural irrigation, municipal water supply, power station circulating water supply, urban pollution treatment, etc.

Classification of horizontal centrifugal pumps

 Horizontal centrifugal pump products are generally classified according to their structural characteristics in a variety of ways, including working pressure, number of working impellers, and impeller inlet mode.


 According to the working pressure:

 Low pressure pump: the pressure is lower than 100m water column;

 Medium pressure pump: the pressure is between 100-650 m water column;

 High pressure pump: the pressure is higher than 650m water column.


 According to the number of working impellers:

 Single stage pump: there is only one impeller on the pump shaft.

 Multistage pump: That is, there are two or more impellers on the pump shaft. At this time, the total head of the pump is the sum of the heads generated by n impellers.


 According to the inlet mode of impeller:

 Single side inlet pump: also called single suction pump, that is, there is only one water inlet on the impeller.

 Double side inlet pump: also called double suction pump, that is, there is an inlet on both sides of the impeller. Its flow is twice as large as that of the single suction pump, which can be approximately regarded as two single suction pump impellers placed back-to-back together.


 By pump shaft position:

 Horizontal pump: the pump shaft is horizontal.

 Vertical pump: the pump shaft is in a vertical position.

 After knowing the horizontal centrifugal pump, what is the horizontal multistage centrifugal pump?

Horizontal Multistage Centrifugal Pump Features

Horizontal Multistage Centrifugal Pump


 A horizontal multistage centrifugal pump is a type of centrifugal pump that consists of multiple stages. The pumps are designed for high-pressure applications such as water supply, irrigation, and petrochemical plants. The multistage design increases the efficiency of the pump and allows it to operate at higher pressures.


 A horizontal multistage centrifugal pump is used to transport fluids by way of a rotating impeller in a housing. The fluid enters the pump through an inlet port and is forced to move outward by the rotation of the impeller. The fluid then moves into the next stage of the pump where it is again forced outward by the rotation of the impeller. This process continues until the fluid reaches the outlet port where it is discharged from the pump.

 A horizontal multistage centrifugal pump is a centrifugal pump that has multiple stages in a horizontal configuration. The advantage of this type of pump is that it can provide a very high level of pressure, which is why it is often used in industrial and commercial applications.

Horizontal Multistage Centrifugal Pump Features


 The Horizontal Centrifugal Multistage Pump from is a great choice for those looking for an affordable and reliable pump. This pump does not have any costly mechanical seals, making it very economical. Additionally, the pump is very easy to maintain and does not require any special tools or installation.


Horizontal Multistage Centrifugal Pump Principle of Operation


 The principle of operation for a horizontal multistage centrifugal pump is relatively simple. The pump consists of a series of impellers, each mounted on a shaft, and housed within a casing. The impellers are arranged in such a way that they draw fluid in from the suction side of the pump and then discharge it under pressure on the discharge side.


 The pump is consists of two or more impellers. The first stage of the pump is referred to as the "primary" stage, while the subsequent stages are called "secondary" stages. The impellers are mounted on a common shaft and are aligned horizontally.


 The first stage of the pump draws water into the impeller from the suction port. The water is then accelerated by the rotating impeller and is discharged into the second stage at high velocity. This high velocity water then enters the second stage impeller and is again accelerated. This process is repeated until the water reaches the discharge port at the required pressure.


Structural Description of Horizontal Multistage Centrifugal Pump

 1. The pump housing is mainly connected by the bearing, front section, middle section, rear section, guide vane, etc. with bolts. The centerline of the suction inlet of the front section is horizontal, and the centerline of the discharge outlet of the rear section is vertical to the horizontal.


 2. The rotor part is mainly composed of bearing, impeller, shaft sleeve, balance plate and other parts installed on the shaft. The parts on the shaft are fastened with flat keys and shaft sleeve nuts to integrate with the shaft. The whole rotor is supported on the pump housing by bearings at both ends, and the number of impellers in the rotor part is determined according to the pump stages.


 3. Bearing part: The D-type pump bearings include sliding bearing and rolling bearing, which are determined by different models and do not bear axial force. During the operation of the pump, the rotor part shall be allowed to swim axially in the pump housing, and the centripetal bearing shall not be used.


 4. The sealing surfaces between the front section, middle section and rear section of the seal pump of the pump are sealed with molybdenum disulfide grease. The rotor part and the fixed part are sealed by the seal ring, guide vane sleeve and packing. When the wear of the seal ring and guide vane sleeve has affected the operation and performance of the pump, they should be replaced in time.


 5. Balance mechanism The balance mechanism is composed of balance ring, balance disc, balance sleeve, etc. The balance mechanism is used to balance the axial force of the pump. In the following operating procedures, please pay attention to the "Warning", "Caution" and "Caution" marking words, which are intended to emphasize personal safety and proper operation and maintenance
