What are the causes of intermittent pump operation?

Our repairs workshop commonly receives pumps with the user reporting intermittent operation as the fault, but what’s the cause of this problem?

Water pumps are often used for maintaining a consistent level of liquid in large tanks and other containers, with a flow valve activating the pump when required. In such applications, the repetitive starting and stopping eventually reduces the life of the electric motor controller and pump assembly. As these components slowly begin to fail, the pump becomes more susceptible to intermittent running.

Irregular operation can also point to a pump being oversized. A pump rated too high for its process generates greater friction losses due to it forcing liquid through the pipes at a faster rate than required. Over time, the pump will begin to run sporadically before failing.

If you’re unhappy with the way your pump is running, why not get in touch with Gibbons? You’ll speak to one of our friendly repairs team, who will be happy to inspect the equipment, diagnose the problem and advise the best course of action.

If your pump’s worth repairing, we’ll have it back to you in full working order in no time. However, if it’s uneconomical to repair your pump, we’ll offer you a suitable replacement from our extensive stock which includes industry-leading Lowara pumps. Give us a call on 01621 868138 or email info@gibbonsgroup.co.uk with your enquiry.
