2.The meaning of model number
Take 2BEC-303-0 for example
2BEC refers to single stage water ring vacuum pump series.
30 tells the the nominal semidiameter of the impeller is 30cm.
3 is the ratio code of the impeller width and diameter. We can easily see that the ratio is 1 according to the formula below.
1----B/D=0.5
2----B/D=0.75
3----B/D=1
5----B/D=1.2
The last number 0 stands for the min suction pressure is 33mbar.(when the number is 1, it refers to the min suction pressure is 160mbar)
