Why vacuubrand Water Pump does not start?
- S
  Shawn McfarlandAug 2, 2025
  Your vacuubrand Water Pump might not start due to several reasons. First, ensure the electrical power cord is properly plugged in. Check the fuse to rule out an electrical supply failure. Verify that the supply voltage matches the pump's requirements as indicated on its rating plate. If the oil temperature is below 54°F (12°C), operate the pump in suitable ambient conditions. If the motor is thermally overloaded, allow it to cool down to below 50°C (122°F), identify, and eliminate the cause of the failure, then manually reset the pump by switching it off or unplugging it. Also, check for overpressure in the outlet line by removing any blockages or opening the valve. Lastly, inspect the oil mist filter for clogs or overfilling; drain oil and replace the filter element if needed.

What to do if vacuubrand Water Pump is too noisy or makes strange noises?
- K
  kochdanaAug 6, 2025
  If your vacuubrand Water Pump is excessively noisy, first check the oil level; if it's too high, lower it to the "max" mark. If the motor is thermally overloaded, allow it to cool down to below 50°C (122°F), identify and eliminate the cause of the failure, ensuring sufficient ventilation. Also, inspect the outlet line for overpressure by removing any blockages or opening the valve.

Why vacuubrand RC 6 Water Pump does not achieve its ultimate vacuum?
- R
  Robert RiveraAug 11, 2025
  If your vacuubrand Water Pump isn't reaching its ultimate vacuum, there might be a leak in the pipeline or vacuum system. Check the pump directly by connecting a vacuum gauge at the pump inlet, then inspect the connection, pipeline, and vacuum system. Ensure you're using lines with a larger diameter and keep them as short as possible. Verify the oil level and top it up if necessary. If the oil is the wrong type or contaminated, change it. Also, allow the pump to reach its operating temperature.

What causes fast aging of the oil in vacuubrand Water Pump?
- R
  Ray BennettAug 17, 2025
  Fast aging of the oil in your vacuubrand Water Pump can occur due to several factors. If you are pumping aggressive gases, use a suitable oil. Condensation in the pump can also degrade the oil, so consider using a separator or cold trap. Check the oil mist filter for defects and replace it if necessary, and also check the safety pop valve.

Why is there oil in the inlet line of my vacuubrand RC 6?
- A
  amy51Aug 22, 2025
  Oil in the inlet line of your vacuubrand Water Pump can be due to back diffusion, which is a small amount of oil or oil film. If this is the case, install a sorption trap or a separator, if necessary.

What causes high oil consumption in vacuubrand RC 6?
- M
  Mrs. Cynthia Flores DVMAug 27, 2025
  High oil consumption in your vacuubrand Water Pump may be normal if there is high inlet pressure or during operation with gas ballast. In these cases, top off the oil whenever necessary and install an oil mist filter at the outlet. If the oil level is too high, lower it to the "max" mark.
