AVOID COSTLY BREAKDOWNS MID-WINTER BY PREPARING NOW
Check the pump is free and not seized up
On some pumps, you can turn the fan by hand. If this is the case, move the fan on your pump system slowly by hand. This method helps prevent seal failure in the event of partial seizure.
Bleed the system to check no air is inside the pump
Trapped air in a pump will reduce the rate at which liquid flows through the pump and has the potential to greatly reduce the capability of the system. Make sure to bleed your system, to ensure there is no air trapped inside.
Check any associated filters (if fitted) are clean
Keeping an eye on any associated filters connected to your pump will help reduce the risk of blockages and ensure the system is moving smoothly. Dependent on the application of a pump system, winter can lead to higher volumes that need to be pumped. Regular cleans will help keep a pump in good service and will help monitor any recurring issues.
Ensure isolation valves are open
We recommend all gate valves are opened fully, then turned back one-half turn to prevent seizure. Pump seizure can prevent pump operation completely, leading to costly downtimes and lots of other issues.
Check expansion bellows
Expansion bellows are a key part of a pump system for ensuring the process works effectively. It’s important to check on them and ensure the following are true:
– Fixing bolts are tight
– The rubber has not perished/is not perishing
Test run pumps
There should be no leaks from the pump. If there is a small weep, leave the pump to run for a short period, to give it time to bed back in. If the leak continues, contact our office to discuss what further actions should be taken.
The pump should run smoothly and without excessive noise. If the noise is coming from the impeller end of the pump, leave it to run for a short period as a build-up of scale may have formed.
Check controls and inverters (where fitted) for any fault codes
Some fault codes may require a simple reset, whilst others require engineer attention. Refer to the manufacturer’s manual or contact our technical support team for advice.
