The core principle of a centrifugal pump is to use high-speed rotational centrifugal force to transport liquid. This process generates centrifugal force, creating a low-pressure zone at the center to draw in new water and a high-pressure zone at the edge to push the water out, thereby continuously delivering water flow.
I. Advantages of Centrifugal Pump Products
Centrifugal pumps have a simple structure, are stable and reliable, provide a uniform flow, and operate smoothly. They play an important role when you need to transport clean water in a stable and efficient manner.

III. Advantages of Centrifugal Pumps
1. Simple structure and durability of centrifugal pump: This is its core advantage. With fewer moving parts and a classic mechanical structure, it means a low failure rate and easy, worry-free maintenance.
2. Smooth flow and stable operation of centrifugal pump: Compared to other types of pumps, it can provide continuous water flow with minimal fluctuation, which is very friendly to pipeline systems and can effectively protect downstream equipment.
3. Wide applicability and complete range of models: From household water boosting to factory cooling circulation, to the water supply systems of entire cities, there are corresponding centrifugal pump models that can perfectly meet these needs.
IV. Centrifugal Pump Safe Operating Procedures
1. Preparations Before Starting the Centrifugal Pump
- Check the fastenings: Ensure that the connection bolts between the centrifugal pump and the base are tight and secure.
- Smooth rotation: Manually turn the pump shaft (jog the pump) to check that it moves easily without sticking or making friction noises. This is a key step to prevent mechanical damage.
- Ensure lubrication: Check that the oil level in the centrifugal pump bearing housing is within the standard range.
- Handle the seals: Inspect the mechanical seal or packing; slight dripping is normal, but there should be no line-like spraying.
- Priming the pump: This is a crucial step unique to centrifugal pumps! Open the vent valve to expel all air from the pump casing until a bubble-free water flow comes out, then close it. This must be done strictly before each start to prevent dry running and damaging the seal.
2. Monitoring During Centrifugal Pump Operation
- Smooth start: Start the pump with the outlet valve closed, and once the motor reaches normal speed, slowly open the outlet valve to the required operating condition.
Emergency Handling for Centrifugal Pumps
Immediately stop the centrifugal pump if any of the following occurs:
- Abnormal vibration or noise from the pump casing.
- Motor current exceeds the rated value.
- Bearing temperature rises sharply (usually should not exceed 70-80°C).
I strongly recommend: If any unknown abnormalities occur, stop the pump first before investigating. Never operate with faults.
Make these steps a habit; then safety becomes not a burden, but a habit.
V. Q&A on Centrifugal Pump Knowledge
1. When starting a centrifugal pump, should the outlet valve be open or closed?
It must be closed at startup to protect the motor under minimal load. After the speed is normal, slowly open the valve.
2. What is the key to selecting a centrifugal pump?
The key parameters are flow rate (how much water is pumped per hour) and head (how high the water can be lifted).
3. What is 'cavitation' in a centrifugal pump? How can it be avoided?
Cavitation in a centrifugal pump occurs when the liquid vaporizes and then condenses inside the pump, creating impact forces that damage the impeller. In my experience: ensure the inlet pipeline is well sealed, and the installation height of the centrifugal pump must not exceed its allowable suction lift.
VI. Application Scenarios of Centrifugal Pumps
1. Centrifugal pumps in the construction and municipal sectors: They serve as core equipment for water supply in high-rise buildings, fire-fighting systems, and HVAC circulation, providing fundamental power for urban operations.
2. Application of centrifugal pumps in industrial production: In factories, they are widely used for cooling tower circulation, boiler feedwater, and process flow transfer, playing a key role in ensuring continuous production.
3. Centrifugal pumps in agricultural irrigation: They draw water from rivers and reservoirs to irrigate large areas of farmland with high efficiency.
4. Centrifugal pumps in water conservancy and public utilities: In major projects such as urban water supply and drainage, and regional water transfer, they are essential backbone pumps.
If you need to transport relatively clean liquids in large volumes and steadily, centrifugal pumps are a good choice. However, different tasks require centrifugal pumps with varying flow rates and head heights, so users should select the appropriate pump according to their specific needs.
