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
