    What to do if my LEYBOLD TRIVAC E2 does not start?
    • D
      Daniel SandersAug 14, 2025
      If your LEYBOLD Water Pump isn't starting, several issues could be the cause. First, check the wiring and repair it if faulty. For three-phase motors, ensure the motor protection switch is properly set up. Also, verify that the power supply voltage matches the motor's rating. Other potential causes include a faulty motor (exchange it), oil temperature being less than 12 °C (warm up the pump and oil or use a different oil), oil being too thick (change the oil), a clogged exhaust filter or line (exchange the filter or clean the line), or a seized pump (repair the pump).

    Why is my LEYBOLD Water Pump getting hotter than usual?
    • J
      Jacqueline PetersenAug 18, 2025
      If your LEYBOLD Water Pump is overheating, several factors could be responsible. Check if the supply of cooling air is obstructed and ensure the pump is properly installed. High ambient temperature or process gas that is too hot can also cause overheating, so ensure the pump is properly installed and change the process if needed. Insufficient oil levels or unsuitable oil types could be the cause, so fill in or change the oil. Other potential issues include obstructed oil circulation (clean or repair the oil channels), a clogged exhaust filter or line (change the filter or clean the line), a faulty exhaust valve (repair the valve), or deviating mains supply voltage (check the power supply rating of the motor and the mains supply).

    What to do if my LEYBOLD TRIVAC E2 Water Pump is extremely loud?
    • A
      Anita ProctorAug 21, 2025
      If your LEYBOLD Water Pump is making excessive noise, start by checking the oil level and top it up if it's too low. High intake pressure can also cause noise, so reduce it if necessary. Other potential causes include a clogged internal demister (clean or replace it), worn coupling bushings (replace them), damaged vanes or bearings (repair the pump), or a faulty motor bearing (exchange the motor bearing).

    Why LEYBOLD TRIVAC E2 does not attain its ultimate pressure?
    • S
      Steven ContrerasAug 26, 2025
      If your LEYBOLD Water Pump isn't reaching its ultimate pressure, consider these possible causes. Ensure you're using the right method of measurement or measuring instrument. Check for external leaks by measuring the pressure directly at the intake port of the pump. Other potential issues include a dirty internal demister or faulty exhaust valve (repair the pump or valve), unsuitable oil (change and possibly degas it), a dirty or leaky intake line (clean or exchange it), or the pump being too small (check process data and possibly change the pump).

    What to do if pumping speed of LEYBOLD Water Pump is too low?
    • A
      Adrienne GilbertAug 28, 2025
      If the pumping speed of your LEYBOLD Water Pump is too low, check if the dirt trap in the intake line is clogged and clean it if necessary. Additionally, a clogged exhaust filter can reduce pumping speed, so exchange the filter element. Finally, ensure that the connection lines are sufficiently wide and short.

    What to do if there is oil in the intake line of my LEYBOLD Water Pump?
    • Y
      ypettyAug 31, 2025
      If you find oil in the intake line or vacuum chamber of your LEYBOLD Water Pump, it could be coming from the system itself, so check the system. Another possibility is a blocked tandem valve, in that case clean or repair it.

    What to do if after switching off LEYBOLD TRIVAC E2 the pressure increases too fast?
    • D
      Dorothy CampbellSep 3, 2025
      If the pressure in the system increases too fast after switching off your LEYBOLD Water Pump, it could indicate a system leak, so check the system. Other potential causes include a faulty tandem valve, inner shaft seal, or exhaust/bypass valve. In such cases, repair the valve(s) or exchange the shaft seal.

    Why is the oil in my LEYBOLD TRIVAC E2 Water Pump turbid?
    • S
      Summer HernandezSep 7, 2025
      If the oil in your LEYBOLD Water Pump is turbid, it's likely due to condensation. You should degas the oil or change the oil and clean the pump.

    Why is there an oil leak at the side of the motor of my LEYBOLD Water Pump?
    • V
      Veronica FarrellSep 12, 2025
      If you notice an oil leak at the side of the motor of your LEYBOLD Water Pump, it's likely due to a damaged or worn-out outer shaft seal. You should exchange the shaft seal.
