Now I have a small 4,2 m3h and 0,05 mbar pump, I’m looking to change it with a bigger pump.
question…I have found 2 pumps…
what is the better choice? less m3/h but higher vacuum, or the second pump? I use it for infusion and degassin, maximum dimension like a car hood
It’s nice to have a system with 2 pumps; A high volume pump to remove the bulk of the air and seat the bag and a second pump capable of reaching a very high vacuum. You could buy pump #2 and use it along with your current pump in this way. Also, a 2 pump system provides a backup if one pump fails.
If you are going to stick with one pump and keep infusing relatively small parts the first choice would be good.
thanks infusible…how big are “relatively small parts”? I have my pump since about 2 years, and if I remember right, it’s good for 2 m2 area.
I don’t have very clear ideas with vacuum conversion…with Pa, mbar, ecc ecc
My actually pump is 5 Pa = 0.05 mbar…on gauge I read -0.95 bar…so 0.003 mbar is -0.997 bar and 2mbar is 0.02 bar
1 mbar = 10−3 bar = 0,001 bar = 100 Pa
why 2 pumps are 0.0xx mbar and the third is 2 mbar?
If I convert my actual pump, 0.05 mbar is 0.00005 bar…but I read -0.95 bar on gauge (not professionale gauge )
25 micron are 0.003 mbar, right? I have find a 128 L/min 25 micron pump. I think this is the better
