Selection of water ring vacuum pumps
Thread Content
This post was last edited by Missergux on 2018-5-22 at 11:39. The ultimate pressure of 33 mbar (3300 kPa) listed in the water ring vacuum pump sample should actually correspond to a vacuum level of -0.098 kPa. Why is it 0.098 MPa? Also, how do you convert 200 L/S to m3/min?
200L/S=200*10^-6m3/(1/3600h)=0.72m3/h
200L=0.2m3 200L/S=0.2*60=12m3/min
Could LZ share the performance parameter table for other larger water ring vacuum pumps? Thank you
I would like to ask why 33 mbar is equal to -0.098 Mpa. How is this calculated?
1 Mpa = 1000 kpa = 10000 mbar. Why is 33 mbar equal to -0.098 Mpa? How is this calculated?
Conversion of vacuum levels in vacuum pumps, formulas for calculating pumping volume; for detailed inquiries, please pay attention

Feel free to discuss any questions regarding the selection of vacuum pumps; I specialize in dry screw pumps
