Why Pfeiffer Vacuum Pascal 2033 SD is not running?
- P
  Peter PorterAug 16, 2025
  There are several reasons why your Pfeiffer Vacuum Water Pump might not be running. It could be due to an incorrect motor power supply, so check the power supply first. If the temperature is too low, reheat the pump and its oil. Gumming of seals after prolonged storage can also be a cause; in this case, disassemble the motor and try to turn the fan manually, or disassemble, clean the pump, replace seals, and reassemble it. If the oil is contaminated after pumping, drain, flush, and refill with clean oil. A damaged motor coupling would require disassembling the motor and replacing the coupling. Lastly, the pump may be seized due to stopping after pumping in difficult conditions; if so, disassemble, clean, hone the scratched metal parts (replace them if necessary), and reassemble.

How to fix a noisy Pfeiffer Vacuum Pascal 2033 SD?
- R
  Rachel BellAug 26, 2025
  A noisy Pfeiffer Vacuum Water Pump can stem from several issues. If the oil level is too high, drain and fill with new oil. Contaminated oil, especially with particles, requires draining, flushing, and refilling with clean oil. Ensure the pump is prepared for the oil being used by checking the pump configuration or the type of oil. An incorrect motor power supply should be checked. Damaged motor bearings necessitate replacing the motor after inspection. An incorrectly set or damaged motor coupling should be checked and replaced if needed. Verify the fan assembly for correctness. Ensure the anti-suckback device is correctly assembled by repeating the assembly. Finally, damaged or stuck vanes should be replaced.

What to do if Pfeiffer Vacuum Water Pump is too hot?
- V
  Victor BurtonAug 28, 2025
  If your Pfeiffer Vacuum Water Pump is overheating, consider these factors. First, ensure the ambient temperature is between 12 and 45 °C. Check that the pump is in a well-ventilated area and that vents are not blocked. If operating at high pressure (P > 22 Torr or 30 mbar), consider an outside cooling device. Examine the exhaust line for excess pressure. Also, check the voltage and replace the motor if it is in over-voltage or short-circuit.

  Lauren DayAug 31, 2025
  If your Pfeiffer Vacuum Water Pump is running too hot, it might be due to contaminated oil, which requires draining, flushing, and refilling with clean oil. Also, the pump may not be prepared for the oil used, or the oil may be unsuitable, so check the pump configuration and the type of oil.

What causes considerable oil losses in Pfeiffer Vacuum Water Pump?
- K
  Krista ClarkSep 3, 2025
  Considerable oil losses in your Pfeiffer Vacuum Water Pump can arise from several causes. If the oil level is too high, drain and refill with new oil. For operation at high pressure, use an HP type oil mist eliminator with oil recovery. If the gas ballast is open, either accidentally or due to pumping of condensable vapors, close it or use a condensate collector, respectively. Check the oil case seal or front seal for leaks and replace the seals if necessary. Finally, readjust if the purges gas flow is too important.

Why Pfeiffer Vacuum Pascal 2033 SD has poor pump tightness when switched off?
- J
  Joshua VegaSep 6, 2025
  Poor pump tightness in your Pfeiffer Vacuum Water Pump when switched off can be attributed to several factors. Ensure the gas ballast is closed. A damaged safety valve should be replaced with a new one. Verify the anti-suckback assembly and repeat the assembly if incorrect. Replace pinched O-rings with new ones, as well as any damaged seals. If the oil is contaminated, drain, flush, and refill with clean oil. If using a plastic HP valve (not tight), check the installation.

Why is there oil in plate of Pfeiffer Vacuum Pascal 2033 SD Water Pump?
- G
  George ReedSep 9, 2025
  Oil in the plate of your Pfeiffer Vacuum Water Pump can occur due to a few reasons. If the oil case and frame were cleaned poorly during reassembly, remove the base and clean them thoroughly. If the oil case seal is pinched, disassemble the oil case, clean the faces, and refit a new seal. Also, front seals may be damaged or the felt saturated, so replace them with new ones.

What to do if Pfeiffer Vacuum Pascal 2033 SD Water Pump vacuum does not produce a vacuum (continued)?
- M
  Michael DavisSep 12, 2025
  If your Pfeiffer Vacuum Water Pump still isn't producing a vacuum, even after initial checks, consider these additional points. Ensure the gas ballast knob is closed (or stop the dry air supply if using dry nitrogen C1, C2 Series). Replace any pinched O-rings with new ones, as well as any damaged seals. Replace damaged HP safety valves. Disassemble and clean any blocked lubrication holes. Verify the anti-noise device setting and repeat the assembly and setting if incorrect. Ensure no parts were forgotten during reassembly by repeating the reassembly. Replace a clogged filter cartridge with a new one. Check the installation if the pump exhaust produces a pressure of 1,125 Torr (1.5 bar). Finally, replace a clogged oil mist eliminator cartridge.

What to do if my Pfeiffer Vacuum Pascal 2033 SD does not produce a vacuum?

  davisstephenNov 18, 2025
  If your Pfeiffer Vacuum Water Pump isn't producing a vacuum, several factors could be responsible. Begin by checking if the motor rotation direction is incorrect and rewire if necessary. Ensure the motor has sufficient power by checking the power supply. A blocked inlet filter can also prevent vacuum generation, so clean the inlet filter. Insufficient oil in the oil case can be another cause, so add oil as needed. If the oil is cold or the oil pump inlet is blocked, warm the pump, disassemble, and clean it. Contaminated oil should be drained, flushed, and replaced with clean oil. Inspect the oil pump inlet for partial blockages and clean the duct if necessary. Damaged LP safety valves should be replaced, and you should also ensure no parts were forgotten during reassembly by repeating the ...

  turnermonicaNov 21, 2025
  If your Pfeiffer Vacuum Water Pump isn't starting, consider these potential causes. If the oil is cold, warm the pump. Ensure there's sufficient oil in the oil case by filling it to the appropriate level. If the oil is contaminated, drain, flush, and refill with clean oil. Check for a partially blocked oil pump inlet and clean the oil pump inlet duct if needed. If lubrication holes are blocked, disassemble and clean them. A damaged vane of the oil pump should be replaced. Verify the anti-suckback system assembly and repeat the assembly and setting if incorrect. If the pump indicates a pressure that is too low or too high, clear the line or check the manometer/plug tightness. If it continues to indicate a pressure that is too low or too high, disassemble, clean and reassemble using maintena...
