How to troubleshoot a BUSCH Water Pump that won't start?
If your BUSCH Water Pump isn't starting, the issue might stem from a few causes. First, the motor might not be getting the correct voltage, so check the power supply. Alternatively, the motor itself could be defective and need replacement. Lastly, a defective coupling (CPL) could be the culprit, requiring you to replace the coupling (CPL).
Why is my BUSCH R5 RB 0021 C Water Pump running too hot?
Several factors can cause your BUSCH Water Pump to overheat. Insufficient cooling could be the issue, so remove any dust and dirt from the machine. Also, ensure that the ambient temperature is within the permitted range. Low oil level can also lead to overheating, so top up the oil. Finally, partially clogged exhaust filters (EF) can cause the machine to run hot, so replace the exhaust filters (EF).
What to do if BUSCH R5 RB 0021 C doesn't reach usual pressure?
If your BUSCH Water Pump isn't reaching its usual suction pressure, several things could be wrong. Start by checking the oil level and topping it up if it's low. The inlet screen (IS) might be partially clogged, so clean it. If your pump has an optional inlet filter cartridge, it might be clogged and need replacement. Internal parts may be worn or damaged.
Why is my BUSCH R5 RB 0021 C Water Pump so noisy?
A noisy BUSCH Water Pump can be caused by a few things. The coupling (CPL) might be worn and need replacement. Stuck vanes or defective bearings may also be the cause.
Why is my BUSCH R5 RB 0021 C fuming or expelling oil?
If your BUSCH Water Pump is fuming or expelling oil droplets, it could be due to partially clogged exhaust filters (EF), so replace them. Another cause might be an exhaust filter (EF) with o-ring that is not fitted properly, so ensure the correct position of the exhaust filters (EF) and the o-rings. If you have a version with an oil return valve and the machine runs for more than 2 hours without interruption, regularly shut down the machine for short periods of time.
What causes abnormal oil consumption in a BUSCH R5 RB 0021 C?
Abnormal oil consumption in your BUSCH Water Pump can be attributed to a couple of factors. Oil leaks may be present. Also, operating the machine at atmospheric pressure for extended periods can lead to increased oil consumption, so make sure that the machine operates under vacuum.
Why is the oil in my BUSCH Water Pump black?
Black oil in your BUSCH Water Pump can indicate a few issues. The oil change intervals might be too long. The inlet filter (optional) could be defective and need replacement. The machine may be running too hot.
What causes emulsified oil in my BUSCH R5 RB 0021 C?
If the oil in your BUSCH Water Pump is emulsified, it could be because the machine sucked in liquids or significant amounts of vapor. Clean the filter of the gas ballast valve (GB). Modify the operational mode.
