Repair Your Centrifugal Pump

Centrifugal pumps are almost always ideal for moving fluids in industrial settings. Most centrifugal pumps are small compared to other pumps with the same output. They are used for various applications, such as circulating freshwater and seawater to cool the main engine of ships.

As with every frequently-used product, problems can arise.

If you notice a minor issue and leave it unattended, it can often lead to pump failure. Industry experts do not recommend using temporary improvised measures to fix these small issues, as they could hasten pump failure and increase expenses for repair. Even if your pump has a minor flaw, start considering repairing or replacing it before it’s too late.



No matter how small a leak is, have it repaired before it escalates to pump failure. Leakage can be caused by excessive or abnormal pressure, temperature, or corrosion, which loosens the pump’s mechanical joints and seals.

Having your pump repaired might involve tightening loose fasteners around a joint or seal. For major leaks at the shaft, the entire mechanical seal or gasket may have to be replaced.


Reduced Liquid Flow

Several flaws can cause reduced flow in your pump. If you notice the impeller rotating the wrong way, this means the motor is wired inaccurately. The pump components with be damaged if the impeller backs off the shaft.

Debris that clogs the pump inlet or discharge must be cleared out to restore optimal liquid flow. If you notice a worn-out impeller, ring or wear plate, the hydraulic capacity of the pump has decreased. Worn-out parts cause clearances to open, which reduces the flow due to greater fluid circulation inside the pump.


Abnormal Noise

Rumbling or rattling noises that are usually accompanied by vibration in pumps are a sign of cavitation. This causes powerful shockwaves inside the pump and can incur major damage to both the impeller and pump housing.
