Why does my Alfa Laval Water Filtration System separator stop?
- A
  Aaron MorganAug 16, 2025
  The Alfa Laval Water Filtration System separator might stop due to several reasons. The safety yoke may have been moved; ensure it's vertical. There could be an overload from incorrect assembly, so check the bowl assembly. High counter pressure can cause this; reduce it to the recommended 40-60 kPa. A tripped frequency converter due to voltage issues is another possibility; check the voltage and use a transformer if unstable.

What to do if my Alfa Laval MIB 303S-13 Water Filtration Systems separator does not start?
- C
  Cameron HernandezAug 19, 2025
  If your Alfa Laval Water Filtration Systems separator isn't starting, check these items: * Ensure the safety yoke is correctly positioned. * Verify power is supplied by checking the mains switch, fuses, and supply line. * Inspect the magnetic safety switch; replace if faulty. * Confirm correct assembly, allowing free rotation of the bowl and motor shaft. * Check the paring disc height adjustment. If the voltage is unstable, connect a transformer.

Why is my Alfa Laval MIB 303S-13 vibrating?
- M
  matthewsmelissaAug 22, 2025
  If your Alfa Laval Water Filtration Systems separator is vibrating, it could be due to a bowl imbalance from insufficient or incorrect cleaning, uneven sediment, or incorrect assembly. Dismantle and clean the separator bowl, ensuring correct reassembly. Alternatively, worn vibration dampers or damaged motor bearings could be the cause. If so, fit new dampers or bearings accordingly.

Why is there low outlet flow in my Alfa Laval MIB 303S-13?
- F
  fsingletonAug 26, 2025
  A low outlet flow in your Alfa Laval Water Filtration Systems could stem from a few issues. First, check the feed line and increase the flow rate if it's too low. Secondly, reduce the counter pressure if it's too high (40-60 kPa recommended). Also, check for leakage due to incorrect assembly, ensuring all screws are tightened and O-rings are correctly fitted. Lastly, verify the separator rotates in the correct direction by checking the electrical connections.

Why is my Alfa Laval MIB 303S-13 Water Filtration Systems making noise?
- I
  ijonesAug 28, 2025
  Noise in your Alfa Laval Water Filtration Systems could be due to incorrect assembly. Dismantle and reassemble it correctly. Damaged motor bearings or worn vibration dampers are other potential causes; in such cases, fit new bearings or dampers.

What to do if oil flows through the water outlet only in my Alfa Laval MIB 303S-13 Water Filtration Systems?
- C
  crosskimberlyAug 31, 2025
  If oil flows through the water outlet only in your Alfa Laval Water Filtration Systems, first check for obstructions in the cleaned oil feed line. If operating in purifier mode, it could be due to insufficient water seal in the bowl. Try adding 1 liter of water to create a new water seal. If the issue persists, the oil density may be too high; stop the separator and fit the black level ring. If the black level ring is already installed, the oil cannot be cleaned because its density is too high.

Why is there insufficient separation result in my Alfa Laval Water Filtration Systems?
- B
  Blake HutchinsonSep 3, 2025
  An insufficient separation result in your Alfa Laval Water Filtration Systems could be due to several reasons. If using a purifier, the black level ring might be too large; replace it with a smaller (white) one. The oil feed rate could be too high; reducing it improves separation. The separation temperature might be too low; adjust the heating. Also, the counter pressure may be too low; increase it until water discharges from the water outlet (40-60 kPa is recommended). Finally, the separator disc stack might be clogged; clean it and shorten the cleaning interval.

What to do if some oil is escaping through the water outlet of my Alfa Laval MIB 303S-13 Water Filtration Systems?
- F
  Frederick DavisSep 6, 2025
  If some oil is escaping through the water outlet of your Alfa Laval Water Filtration Systems, it might be due to high counter pressure; reduce it to 40-60 kPa. Alternatively, the separator disc stack could be clogged; clean it and shorten the cleaning interval. Ensure the screws fastening the bowl hood or paring disc knob are tightened to prevent leakage. If operating in purifier mode, check for sufficient sealing between the bottom disc and bowl bottom, ensuring no O-rings are missing and the separator is correctly assembled.

What to do if there is no outlet flow through clean oil outlet or water drain in my Alfa Laval MIB 303S-13 Water Filtration Systems?
- K
  Kevin WeaverSep 9, 2025
  If there's no outlet flow through either the clean oil outlet or water drain in your Alfa Laval Water Filtration Systems, first check the feed line for any issues with valves, the feed pump, or filters. Also, check if the separator has stopped.

Why is there oil leakage through the water outlet when my Alfa Laval MIB 303S-13 separator is not running?
- M
  Marie JonesSep 12, 2025
  If you're experiencing oil leakage through the water outlet when your Alfa Laval Water Filtration Systems separator is not running, it's likely due to oil being siphoned from the oil tank. To resolve this, close the valves on both the feed and outlet sides of the separator.
