Review on Huanyu Oilless Diaphragm Vacuum Pump Oil Free Anticorrosive Pump 30L/Min Lab R&D For Filtration Extraction Apsorption 110V (Ordinary Type, GM-0.5A(Single Pump)) by Jesus Baker

Revainrating 5 out of 5

Nice pump! for my opinion

We have the GM-0.5A standard pump (blue). So far, we have gotten 250+ hours of continuous runtime on the pump. We are actively air cooling it, but that might not be necessary.It’s not super quiet, but it seems very sturdy and well built.Even after a week and a half of continuous use, I haven’t noticed any changes in sound or temperature that would indicate any issues.Seems like a good pump! I’ll keep this updated as we accrue more hours.[Update] we have now been running the pump continuously for four months with no air cooling.

Pros
  • The pump works perfectly and meets the functional needs of my facility.
Cons
  • The Huanyu Oilless Diaphragm Vacuum Pump claims to be an anti-corrosive and oil-free machine, but it makes an unbearable amount of noise while working, making it unsuitable for quiet lab environments.
