What distinguishes the two types of inline centrifugal pumps? And which one is best suited to your process application? The following will provide answers to your questions.
Differences in Fundamental Design
Choosing which pump to use in your operation may be influenced by a number of factors. These include the pump’s overall ease of operation and maintenance, installation space, and functionality. With this in mind, let’s take a look at some of the benefits and drawbacks of each pump design.
| NO. | Comparison Factor | Horizontal Centrifugal Pump | Vertical Centrifugal pump |
|---|---|---|---|
| 01 | Position of shaft | Horizontal | Vertical |
| 02 | Space Availability | Requires more floor space but less headroom | Requires less floor space but more headroom |
| 03 | Working pressure and Temperature | Can’t handle more pressure and temperature of fluid on the suction side | Can work efficiently with higher pressure and temperature condition |
| 04 | NPSH | Can not be altered | Can be altered as per requirement |
| 05 | Efficiency | Comparatively high efficient | Comparatively less efficient |
| 06 | Priming | Requires (Except self-priming pumps) | Not required |
| 07 | Maintenance and Installation | Easy | Comparatively tough |
The Distinction Between Vertical and Horizontal Pumps
1. Physical appearance
2. Form of connection
Vertical pumps connect from the bottom to the top. On the base, the horizontal pumps are arranged longitudinally. Vertical water pumps, such as vertical centrifugal pumps, are commonly referred to as pipeline pumps. The sub-mouth connects the motor and the pump body. Horizontal pumps are linked together by coupling and a motor. It must be corrected on a regular basis.
3. Space
4. Maintenance
5. Establishment
The vertical pump is integrated and simple to install. The horizontal pump, on the other hand, requires precise adjustment after installation.
Horizontal pumps are more cost-effective than vertical pumps.
Vertical Pump Advantages and Disadvantages
Advantage
1. The flow rate is constant and even, the work is stable, and it is simple to adjust.
2. Pump wear parts are few and simple to manage and maintain.
3. High-speed motors or steam turbines can be directly connected. The structure is simple and compact. The size and weight are less than that of the same flow reciprocating pump. It is inexpensive.
Disadvantage
1. The pump’s response to changes in liquid viscosity is more sensitive. The cavity of the liquid advances a pitch with each turn of the screw. The liquid spirals its way from one sealed cavity pressure to another as the screw rotates continuously. Finally, squeeze the pump body out.
2. A vertical pump is a transport pump with a single screw. Its primary working components are an eccentric screw and a screw bush that is attached to the inner surface of the double-line spiral surface.
3. The power is not excessive. It is ideal for industrial and urban drainage. It is also very useful in the process of pressurized water supply in high-rise buildings. We are all aware of the importance of modern industrial and urban drainage to human work and life. Vertical centrifugal pumps play an important role in these applications.
Horizontal Pumps Advantages and Disadvantages
Advantage
1. Effortless operation. The pump shaft and impeller’s absolute concentricity provide excellent static and dynamic balance, ensuring smooth operation with no vibration.
2. It is watertight. Different materials of cemented carbide seal ensure no leakage of different media transmission.
3. Low noise level. The pump is supported by two low-noise bearings. Smooth operation, with only a faint sound from the motor.
4. The failure rate is low. The structure is straightforward and reasonable. The key component employs international T first-class quality matching. The overall machine has a much longer working time due to no failures.
5. Simple to maintain. The seal and bearing are simple to replace.
6, Saves space by exporting to the left, right, or all three directions. The pipeline layout is then installed to save space.
Disadvantage
Principal drawbacks: Because the horizontal centrifugal pump’s spindle position is horizontal. It takes up more space than a vertical centrifugal pump when installed. Because of the suction height limitation, the water pump’s installation position is very low, making it easily damp and flooded. It will have an impact on operational safety.
