Centrifugal pumps are vital in many industries, like oil plants and water systems. But when they break, they can cause big problems, like costly delays and safety risks. Knowing centrifugal pump failure causes and picking reliable pump types for industry can cut these risks and boost system performance.
This blog looks at common pump breakdowns, why they happen, and how choosing the right centrifugal pump, like those from Yantai Longgang Pump Industry, can stop them.
Why Centrifugal Pumps Break Down
Centrifugal pumps move liquids in tough jobs, but they can still fail. These failures come from mechanical issues, wrong pump choices, or human mistakes. By finding the main reasons, industries can act early to keep pumps running smoothly.
Main Reasons for Centrifugal Pump Failures
Several things cause centrifugal pump breakdowns. Here’s a table listing the top issues and their reasons:
| Breakdown Type | Main Reasons |
| Cavitation | Low pressure at the inlet, hot liquids, or wrong pump size |
| Seal Failure | Poor alignment, bad setup, or wrong seal materials |
| Bearing Wear | Too much load, not enough oil, or dirty oil |
| Impeller Harm | Rough liquids, cavitation, or wrong pump use |
| Shaking and Noise | Bad alignment, uneven impellers, or wrong pump for the job |
- Cavitation: This happens when bubbles form and pop inside the pump. It causes damage and wear. It’s often due to low suction pressure or running the pump outside its design.
- Seal Failure: Seals break from too much heat, wrong materials, or poor alignment. This leads to leaks and pump damage.
- Bearing Wear: Bearings keep pumps steady. Not enough oil or dirty oil causes overheating and early wear.
- Impeller Harm: Harsh or corrosive liquids wear down impellers. This lowers efficiency and flow.
- Shaking and Noise: Too much shaking comes from bad alignment or wrong pump speeds. It stresses the pump.
Knowing these centrifugal pump failure causes helps prevent them. The next step is choosing a pump that fits your needs.
Picking Reliable Pump Types for Industry
Choosing the right centrifugal pump stops failures and keeps things running well. Different pumps work for different jobs. Picking the right one saves time and money.
What to Think About When Choosing a Pump
When picking a centrifugal pump, keep these points in mind to make it last:
- Liquid Type: Check the liquid’s thickness, harshness, and heat. Harsh liquids need pumps with strong materials, like stainless steel.
- Job Conditions: Look at pressure, flow, and heat needs. Make sure the pump works in its best range.
- Pump Style: Pick a pump type that fits, like single-stage, multi-stage, or double-suction designs.
- Care Needs: Choose pumps with easy-to-reach parts and sturdy builds to cut down on fixes.
By matching your pump to these points, you avoid centrifugal pump failure causes and make systems last longer.
Strong Pump Types for Industrial Jobs
Yantai Longgang Pump Industry offers reliable pump types for industry. Each is built for specific tasks. Here are some examples:
BB2 Radial Dissection Chemical Process Centrifugal Pump
The LBD(BB2) Radial Dissection Chemical Process Centrifugal Pump works well for oil and chemical jobs. Its split design and tough build handle hot and harsh liquids. This cuts risks of impeller harm and seal breakdowns. It meets API 610 standards, ensuring strong and steady work in tough settings.
BB1 Axial Split Double Suction Centrifugal Pump
For big-flow jobs, the LAD(BB1) Axial Split Double Suction Centrifugal Pump is great. Its double-suction impeller lowers cavitation and balances forces. This reduces shaking and makes bearings last longer. It’s used in water systems and oil refining.
BB4 High-Pressure Segmented Multi-Stage Centrifugal Pump
The LDD(BB4) High-Pressure Segmented Multi-Stage Centrifugal Pump is made for high-pressure tasks, like boiler feed water and seawater desalination. Its smart design and oiled bearings improve efficiency and stop bearing wear.
These pumps show how the right design tackles centrifugal pump failure causes. They ensure steady work in many industries.
Real-World Examples: Longgang’s Tough Pumps
Yantai Longgang Pump Industry makes pumps that last and avoid common breakdowns. Here are two examples from real projects:
Oil Industry: BB2 Pump Wins
In a big oil refinery, a client had seal breakdowns from hot liquids. They switched to Longgang’s LBD(BB2) pump. It has a double volute casing and API 682-compliant seals. This cut seal-related stops by 80%. The pump handles harsh liquids and high heat well, keeping work steady.
Seawater Desalination: BB4 Pump Strength
A desalination plant had cavitation in its high-pressure pumps. Longgang’s LDD(BB4) pump fixed this with its low-NPSH design and strong impeller. It boosted efficiency by 15%. Its oiled bearings also made them last longer, cutting repair costs.
These examples show how Longgang’s pumps solve centrifugal pump failure causes with smart designs and strong materials.
Easy Ways to Stop Pump Breakdowns
Choosing reliable pump types for industry is key, but regular care matters too. Here are simple ways to keep pumps working:
- Check Often: Look at bearings, seals, and impellers regularly to spot wear early.
- Oil Right: Use the right oil for bearings to avoid overheating.
- Align Well: Make sure the pump and motor line up to cut shaking and stress.
- Watch Closely: Use sensors for heat and shaking to catch problems early.
- Match Liquids: Ensure pump materials work with the liquid to avoid wear or rust.
Using these steps with the right pump choice cuts downtime and repair costs.

FAQs on Centrifugal Pump Breakdowns
What are the top centrifugal pump failure causes?
The main centrifugal pump failure causes are cavitation, seal breakdowns, bearing wear, impeller harm, and shaking. These happen from wrong pump choices, poor care, or running pumps outside their design.
How do I pick reliable pump types for industry jobs?
Choose pumps based on the liquid, job conditions, and care needs. Double-suction pumps work for big flows. Multi-stage pumps are good for high pressure. Ensure pumps meet standards like API 610.
What care stops centrifugal pump breakdowns?
Check bearings, seals, and impellers often. Oil bearings correctly and align pumps well. Use sensors to watch for heat or shaking. Match pump materials to the liquid to avoid rust.
How does cavitation hurt centrifugal pump performance?
Cavitation happens when bubbles pop inside the pump. It damages parts and lowers efficiency. Prevent it with enough suction pressure and pumps designed for low NPSH.
