If your DAB Water Pump motor makes noise but doesn't start, verify that the supply voltage matches the voltage on the pump label. Check the electrical connections and correct any errors. Confirm that all phases are present and restore any missing phase. Also, inspect the pump and motor for obstructions and remove them.
Why is my DAB KVC not delivering water?
If your DAB Water Pump isn't delivering water, check the priming. For three-phase motors, ensure the direction of rotation is correct by inverting the connection of two supply wires. Also, verify that the suction level isn't too high. If the intake pipe is insufficient or too long, replace it with a larger diameter pipe. Finally, check for and clean any blockages in the foot valve or intake pipe.
Why does my DAB KVC vibrate and operate noisily?
If your DAB Water Pump is vibrating and operating noisily, ensure that the pump and pipes are firmly anchored. Check for cavitation in the pump and reduce the intake height or check for load losses. If the pump is running above its plate characteristics, reduce the flow rate. Also, check the state of wear of the bearings if the pump is not turning freely.
How to fix insufficient flow in my DAB KVC Water Pump?
If your DAB Water Pump supplies insufficient flow, remove any blockage from the foot valve or impeller; replace the impeller if it's worn down. Replace the intake pipe with one of a larger diameter if it's insufficient. Ensure the direction of rotation is correct by inverting the connection of two supply wires.
Why does the motor protection trip too frequently on my DAB KVC?
If the motor protection in your DAB Water Pump trips too frequently, ensure the environment temperature isn't too high by providing suitable ventilation where the pump is installed. Check the calibration of the protection and calibrate it at a current value suitable for the motor absorption at full load.
What causes the motor protection to trip immediately after starting my DAB Water Pump?
If the external motor protection of your DAB Water Pump trips immediately after starting, verify that all phases are present and restore any missing phase. Inspect the protection for open or dirty contacts and change or clean the component concerned. Look for faulty insulation of the motor by checking the phase resistance and insulation to earth; change the motor casing with the stator or reset any cables discharging to earth.
How to fix a DAB Water Pump that does not prime?
If your DAB Water Pump does not prime, check if the intake pipe or the foot valve is taking in air. Check the suction pipe and repeat the priming operations. Also, check the slope of the suction pipe and correct the inclination of the intake pipe.
Why is my DAB KVC motor turning with difficulty?
If the motor of your DAB Water Pump turns with difficulty, verify that the supply voltage is at an acceptable valve. Check whether any moving parts are scraping against fixed parts and eliminate the cause of the scraping. Inspect the state of the bearings and change any worn bearings.
Why is the flow rate of my DAB KVC not constant?
If your DAB Water Pump's flow rate isn't constant, it may be due to intake pressure being too low. Also, the intake pipe or pump might be partly blocked by impurities. Remove any clog to resolve this issue.
What to do if my DAB KVC Water Pump motor does not start and makes no noise?
If your DAB Water Pump motor doesn't start and makes no noise, start by checking the protection fuses and replace them if they are burnt-out. Then, inspect the electric connections and correct any errors. Also, ensure the motor is live. For single-phased motors, the motor protector might have cut off the motor due to overheating. In this case, wait for it to automatically reset once the temperature has fallen below the maximum limit.
