What to do if my BUSCH MINK MM 1144 BV Water Pump does not start?
If your BUSCH Water Pump isn't starting, it could be due to several reasons. First, check the power supply to ensure the motor is receiving the correct voltage. If the power supply is adequate, the motor itself might be defective and need replacement. Another potential issue is a defective coupling (CPL), which would also require replacement.
Why is my BUSCH Water Pump running too hot?
If your BUSCH Water Pump is running too hot, several factors could be the cause. First, check for insufficient cooling by removing any dust and dirt from the machine. The ambient temperature may be too high, so ensure it's within the permitted range as specified in the Technical Data. Also, verify that the temperature of the process gases at the inlet is within the permitted limits, as detailed in the Technical Data. Finally, check the oil level and top it up if it is too low.
Why is my BUSCH MINK MM 1144 BV running very noisily?
If your BUSCH Water Pump is excessively noisy, there are a few potential causes. One possibility is a worn coupling (CPL), which would need to be replaced. Another cause could be that the oil level is too low, so you should top up the oil. It could also be due to defective bearings, in which case you should contact Busch to repair the machine.
What to do if my BUSCH MINK MM 1144 BV does not reach the usual pressure on the suction connection?
If your BUSCH Water Pump isn't reaching the usual pressure on the suction connection, it could be due to a few reasons. The inlet screen (IS) might be partially clogged, so you should clean it. If your pump has an optional inlet filter cartridge, it may be partially clogged and need replacement. It is also possible that internal parts are worn or damaged, in which case you should contact Busch to repair the machine.
What to do if my BUSCH MINK MM 1144 BV starts, but labours or runs noisily or rattles?
If your BUSCH Water Pump starts but runs noisily, check for loose connections in the drive motor terminal box and ensure all motor coils are properly connected, especially on motors with six coils; tighten or replace any loose connections. Also, verify that the pump is running in the correct direction. Foreign objects or stuck bearings inside the pump could also be the cause.
Why is my BUSCH MINK MM 1144 BV blocked?
Your BUSCH Water Pump could be blocked due to solid foreign matter entering the pump. Make sure the suction line is equipped with a screen and consider adding a filter. Another cause could be corrosion from remaining condensate. Check the process.
What to do if the temperature monitoring has tripped on my BUSCH MINK MM 1144 BV Water Pump?
If the temperature monitoring has tripped on your BUSCH Water Pump, indicating that the permissible temperature at the outlet has been exceeded and the pump has shut down, the problem may be insufficient air ventilation. Ensure that dust or dirt isn't impeding the cooling of the pump; clean the fan cowlings, fan wheels, ventilation grilles, and cooling fins. Also, make sure that the ambient or inlet gas temperature is not too high, and that the mains frequency or voltage are within the tolerance range. Partial clogging of filters or screens, or in the suction, discharge, or pressure line, or lines with too small diameter may also be the cause; remove any blockages or use larger diameter lines.
What to do if the drive motor is running, but the BUSCH Water Pump stands still?
If the drive motor is running, but the BUSCH Water Pump remains still, the coupling between the drive motor and the pump is likely defective and needs replacement.
