Why VWR RV2.5+ Water Pump does not start?

  If your VWR Water Pump isn't starting, there could be several reasons. First, ensure there is a power supply. If power isn't the issue, the motor or coupling might be defective, requiring service or repair/exchange. If the starting temperature is too low, put the vacuum pump in a warm place corresponding to the starting temperature. Also, if the oil is resinous after long storage, consider general maintenance and cleaning.

How to fix VWR RV2.5+ Water Pump that runs hot?

  If your VWR Water Pump is running hot, the issue could be due to several reasons. Using oil with too low a viscosity can cause overheating, so you should perform an oil change. A high ambient temperature around the vacuum pump can also contribute, so change the location. If these aren't the cause, the motor might be defective and need to be exchanged. High built-up pressure in the oil casing (over 0.5 bar) can also lead to overheating; in this case, check the exhaust pipe and change the filter insert.

  If your VWR Water Pump is running very loudly, the motor, rotary vanes, and/or shaft seal rings might be defective, or the rotary vane spring could be broken. In such cases, consider repair and/or exchange of the affected components.

Why VWR RV2.5+ Water Pump has heavy loss of oil?

  gardnerteresaAug 29, 2025
  Heavy oil loss in your VWR Water Pump can stem from a defective work or pressure control valve, leading to oil mist emission, so you should exchange it. Alternatively, leaks from the oil casing due to a defective shaft seal or oil casing seals may be the cause, which requires repair and/or exchange.

What to do if VWR Water Pump is not vacuum-tight when switched off?
- Z
  zscottSep 3, 2025
  If your VWR Water Pump isn't vacuum-tight when switched off, leading to a possible rise in oil pressure, it could be due to a defective intake valve or a defective shaft seal ring on the drive side or oil pump, which require repair and/or exchange. Another possible cause is an opened gas ballast valve; close it.
