Questions and Answers

Why is my LEYBOLD Water Pump getting hotter than usual?
- M
  Mr. Mark ArnoldAug 13, 2025
  Your LEYBOLD Water Pump may be overheating due to several reasons. Check if the cooling air supply is obstructed and ensure correct setup. High ambient temperature or hot process gas can also cause this. Other potential causes include low or unsuitable oil levels, obstructed oil cycles, malfunctioning exhaust valves, a clogged exhaust filter or line, or a worn-out pump module. Address each of these to resolve the issue.

What to do if my LEYBOLD Water Pump does not start?
- R
  Ryan MillerAug 17, 2025
  If your LEYBOLD Water Pump isn't starting, several factors could be responsible. First, check and repair any malfunctioning wiring. For 3-phase motors, ensure the motor protection switch is properly set. The operating voltage must match the motor, or the motor may need replacement. Low oil temperature (below 12 °C) can also prevent starting; heat the pump and oil or use a different oil. Viscous oil or a clogged exhaust filter/line are other potential culprits; change the oil, replace the filter, or clean the exhaust line as needed.

Why is my LEYBOLD TRIVAC B Water Pump excessively noisy?
- L
  Larry LawsonAug 20, 2025
  Excessive noise in your LEYBOLD Water Pump can stem from several issues. Check the oil level; if it's too low to be visible, add oil. Other causes include a clogged silencing nozzle or internal demister (clean or replace them), high intake pressure (lower it), a worn coupling element (install a new one), or damaged vanes/bearings (repair the pump).

What to do if LEYBOLD TRIVAC B pumping speed is too low?
- M
  Michael GrahamAug 25, 2025
  If the pumping speed of your LEYBOLD Water Pump is too low, start by checking the dirt trap in the intake port for clogs. Clean it, and consider installing a dust filter in the intake line as a precaution. Also, inspect the exhaust filter for clogs and exchange the filter element if necessary. Finally, ensure that the connecting lines are adequately wide and short.

What to do if my LEYBOLD TRIVAC B does not reach ultimate pressure?
- T
  Taylor HodgeAug 29, 2025
  If your LEYBOLD Water Pump isn't reaching ultimate pressure, consider these potential causes: unsuitable measuring technique or gauge (use correct ones), external leaks (measure pressure directly at the pump's intake port), malfunctioning anti-suckback or exhaust valves (repair them), unsuitable oil (change and degas if necessary), dirty intake line (clean vacuum lines), or an undersized pump (check process data and replace if needed).

What causes oil in the intake line or vacuum vessel of my LEYBOLD TRIVAC B?
- P
  plawrenceSep 1, 2025
  Oil in the intake line or vacuum vessel of your LEYBOLD Water Pump can be due to several reasons. The oil might be coming from the vacuum system itself, so check the system. Alternatively, the anti-suckback valve may be obstructed (clean or repair it), or its sealing surfaces may be damaged or dirty (clean or repair the valve and intake port). Finally, the oil level might be too high; drain any excess oil.

What to do if pressure in system rises too fast after switching off LEYBOLD Water Pump under vacuum?
- L
  Luis SmithSep 5, 2025
  If the pressure in the system rises too quickly after switching off your LEYBOLD Water Pump under vacuum, it could indicate a system leak (check the system) or a malfunctioning anti-suckback valve (repair the valve).

Why is the oil in my LEYBOLD TRIVAC B turbid?
- C
  craignolanSep 8, 2025
  Turbid oil in your LEYBOLD Water Pump is likely due to condensation. Degas the oil or change it and clean the pump.
