TL;DR: Add/replace oil and calibrate the gauge, but otherwise good pump.When I first received the pump and, naturally, tried to boil some water, I was utterly disappointed. It was not reaching vacuum at all, and was getting quite hot.After reading comments to similar pumps here I've tightened all joints the best I could, but it didn't help at all.The oil level was within limits, but closer to the min level. So I decided to add some. And it did the trick, the pump pulled a fairly good vacuum, the water started to boil fairly quickly, and the gauge went below -1 atm.This brings me to the other point. The gauge is not calibrated, so its reading is not accurate. Keep that in mind.Order some oil with the pump, don't expect it to be ready to go. Mine wasn't.

The one measurement that is most needed but not listed is the actual internal dimensions of the drum.For information it measures 225mm in diameter and 270mm in depth.Also, you need to be aware the instructions say not to run it without sufficient oil in the pump; but it arrives with the oil at the minimum mark!You need the right High Speed Vacuum Oil to top it up (HFV 32) ... be worth ordering some at the same time.Seems to work fine but cannot fully check because I've had to order the oil !!It also arrives in parts with no instructions on assembly ... not difficult but I assume the "O" rings supplied fit inside the brass inlet port ... cannot see where else they could go.

Solid well built unit. Glass clear top is a bonus to be able to monitor what's happening. Good value for money. Would happily buy again.

Very good service
