Why does my Kolmeks FC stop by itself or run irregular and noisy?
If your Kolmeks Water Pump stops by itself or runs irregularly and noisily, it could be due to a defective supply voltage, which requires checking. Another possibility is a missing phase, in which case you should check and repair fuses and cable connections. In some instances, the frequency converter or electric motor might be damaged, necessitating replacement.
How to fix a noisy Kolmeks FC Water Pump?
If your Kolmeks Water Pump is noisy, it could be due to cavitation, which can be addressed by increasing the suction pressure. Alternatively, the pump's pressure difference might be too high, requiring a decrease in flow. A faulty shaft seal or bearings could also be the cause, necessitating replacement. Electrical noise from the frequency converter or electric motor might also contribute; if necessary, correct the parameters of the frequency converter.
What to do if my Kolmeks FC Water Pump is not pumping?
If your Kolmeks Water Pump is not pumping, it could be due to air in the pump or system, which requires deaeration. Alternatively, the suction pressure may be too low, requiring an increase. Another possibility is that circulation is closed off by the valves; ensure the valves are open.
Why is my Kolmeks Water Pump running at maximum frequency without flow changes?
If your Kolmeks Water Pump is running only with the maximum frequency, which doesn’t vary in accordance with the requirements of flow changes, the reference signal might be too high. If you intend to use the potentiometer as the source of reference, adjust the value accordingly. Another possibility is that the feedback transmitter is missing or the signal is wrong, so check and repair the feedback signal and/or connections. The pipes of the pressure or differential pressure transducer may also be blocked or incorrectly connected; in this case, check and repair the connections and blockings of the pipes.
How to fix a leaking shaft seal on a Kolmeks FC Water Pump?
If the shaft seal of your Kolmeks Water Pump is leaking, it is likely due to wearing or the pump having run dry. The suggested solution is to change the seal.
