Why is my Refco Water Pump not reaching enough vacuum?
- R
  Raymond BuchananAug 15, 2025
  If your Refco Water Pump isn't achieving sufficient vacuum, several factors could be at play. Ensure the gas ballast is closed. Check that the intake port cap is tightly screwed on and that its O-ring is in good condition; replace the O-ring if faulty. Verify the oil level and replenish if low. If the oil appears muddy or contaminated, change it. Inspect the pipe for leaks and seal them. If the pump has been used extensively, it might be worn out and require repair or replacement.

How to troubleshoot Refco Water Pump not running at full speed?

  Ray DuarteAug 18, 2025
  If your Refco Water Pump is not running at full speed, it could be due to several reasons. The oil temperature might be too low; try placing the pump in a warmer environment. The oil could be unsuitable (too thick); consider changing it with REFCO oil. A dirty pump can also cause this issue, so changing the oil is recommended. The connection cable might be too long, so try using a shorter one. Also, ensure that the supply voltage is within +/- 10% of the pump's design specification.

  If you observe extensive oil mist coming from the oil mist filter of your Refco Water Pump, it's likely because the pump pressure is equal to atmospheric pressure. The oil mist should disappear once a certain vacuum level has been reached.
