Greetings all,
I purchased a pump off eBay last year. I don't see any manufacturer markings so I don't know what brand of pump it is. My first question is about oil replacement...I don't see a place to put the oil. Is it possible this is an oil less pump?
Second question refers to the vacuum...when I place my finger over the port it maxes out at a hair over -25 mmHg. Is this sufficient for vacuum infusion or is -30 mmHg mandatory?
Thanks in advance!

Judging by the shape of the top, that will be a diaphragm pump so will not have any oil

The elevation you live can reduce the atmospheric pressure you are reading on the gauge.

I've also found analogue gauges to be pretty useless when it comes to reading the vacuum level...
