Why is the oil in my BUSCH Water Pump black?
If the oil in your BUSCH Water Pump is black, it might be because the oil change intervals are too long. To resolve this, drain the old oil and fill in new oil.
Why my BUSCH Water Pump does not reach the usual pressure?
Your BUSCH Water Pump may not be reaching its usual pressure due to several reasons. The vacuum system or suction line might not be leak-tight, so check hose or pipe connections. Process deposits on the pumping components can also cause this, so flush the pump carefully. If a mesh screen or filter is installed, it may be clogged, requiring cleaning or replacement. A partial clogging or too small diameter in the suction, discharge, or pressure line can also be the cause, so remove any clogging and use a larger diameter line. Internal parts may also be worn or damaged.
What to do if my BUSCH Water Pump does not start?
If your BUSCH Water Pump isn't starting, several factors could be at play. First, ensure the drive motor is receiving the correct voltage. Also, check if the drive motor starter overload protection is appropriately set. Examine the fuses and the connection cable dimensions. It's also possible that the pump or motor is blocked, so attempt to turn the screws rotors manually.
Why is my BUSCH Water Pump running very hot?
If your BUSCH Water Pump is running very hot, check the external cooling liquid flow and adjust if necessary. Ensure the ambient temperature and the temperature of the inlet gas are within permitted ranges. Also, verify that the mains frequency or voltage is within the tolerance range and clean or replace the mesh screen or inlet air filter if they are partially clogged.
Why is my BUSCH Water Pump running very noisily?
If your BUSCH Water Pump is running very noisily, the coupling element might be worn and needs replacement.
How to fix a BUSCH Water Pump that starts, but labours or runs noisily or rattles?
If your BUSCH Water Pump starts but labors, runs noisily, or rattles, check the connections in the drive motor terminal box against the connection diagram and tighten or replace any loose connections. If the pump runs in the wrong direction, verification and rectification may be needed. If there was a standstill over several weeks or months, let the pump run warm with the inlet closed. Ensure proper oil viscosity, quantity, and type, and perform an oil change if needed.
What to do if my BUSCH Water Pump is blocked?
If your BUSCH Water Pump is blocked, the recirculating pump might be blocked and needs cleaning. Solid foreign matter might have entered the pump.
