Why EBARA Water Pump has low rotation speed?
If your EBARA Water Pump has a low rotation speed, it may be caused by low voltage (change the nominal voltage), poor Star/Delta commutation (correct the cabling), overloading (reduce the current), or a defective electrical connection (correct the electrical connections).
Why is my EBARA Water Pump flow rate so low?
If your EBARA Water Pump has a low flow rate, several factors could be responsible. The direction of rotation might not be correct, so you should correct the electrical connections. There could be low voltage, requiring you to check the power supply. Also, check for blockages in the bottom valve or filter, and remove any foreign bodies. Air entering the system could also be the cause; in that case, check and repair the suction pipe and shaft seal. Leakage in the delivery pipe can also cause low flow; check and repair as needed. If none of these issues are present, the impeller might be worn, so check the impeller. Significant head losses in the system, high liquid temperature, or cavitation could also be the cause and require further review or expert advice.
How to reduce vibration and noise in my EBARA GS?
Excessive vibration and noise in your EBARA Water Pump can be caused by several factors. A fault in the installation is possible, so check the installation. Damaged bearings could also be the source, requiring replacement. If the flow rate is too high or too low, adjust the delivery valve accordingly. An impeller blockage can also cause these issues, so remove any foreign bodies. Incorrect rotation direction can also lead to these problems; check and correct the connection. Friction in the rotation areas can also be a cause. Cavitation is another potential cause. Vibrations in the piping may also contribute to the noise and vibration.
What causes my EBARA Water Pump motor to overheat and smell bad?
If your EBARA Water Pump motor is overheating and emitting smoke or a bad smell, high power surges could be the cause; correct the power surges. Another possibility is a blocked fan; release the fan. The voltage may also be wrong; change the motor for one with the appropriate voltage.
Why does my EBARA GS Water Pump have no flow rate?
If your EBARA Water Pump has no flow rate, it could be due to several reasons. The pump may not be turning, so check that the impeller is free. The delivery valve might be closed or half-closed, so open the valve. The suction head could also be too high for the pump, so check the project.
Why EBARA Water Pump shaft seal is leaking excessively?
Excessive water leakage from the shaft seal of your EBARA Water Pump may be due to defective fitting of the mechanical seal (fit it correctly), a damaged mechanical seal (replace the mechanical seal), overpressure in delivery (review the project), or a bent shaft (repair in specialist workshop).
What to do if EBARA Water Pump has no flow rate?
If your EBARA Water Pump has no flow rate, it could be because the pump does not turn (check that the impeller is free), the delivery valve is closed or half-closed (open the valve), or the suction head is too high for the pump (check the project).
Why EBARA Water Pump stops abruptly after initial water flow?
If water comes out initially from your EBARA Water Pump and then stops abruptly, it may be because the pump has not been primed correctly (prime the pump correctly), air is entering the system (check and repair the suction pipe and shaft seal), there are air bubbles in the suction pipes (vent the pipes), or the suction head is too high for the pump (review the project).
Why my EBARA Water Pump motor will not start?
If the EBARA Water Pump motor won't start, possible causes include a faulty control panel (check all conditions), motor failure (repair the motor), power supply faults (check and repair), friction on the rotation shaft (rotate by hand and reassemble), or a clogged pump (remove foreign bodies).
What causes low rotation speed in my EBARA GS Water Pump?
A low rotation speed in your EBARA Water Pump can be caused by several factors. Low voltage is a possibility, so change the nominal voltage. Poor Star/Delta commutation could also be the cause, so correct the cabling. Overloading can also reduce the rotation speed; reduce the current. Finally, a defective electrical connection might be the issue; correct the electrical connections.
