Do you know the different points between DG46-50x12 and DG45-80X8? If you have the same parameters, how to select the pump between them? Or do you know the advantages and disadvantages between them? Now let me tell you which one you should select.
There are some similar points between them:
- Same material: the standard material is cast steel.
- Same pump type and structure: these two models belong to boiler feed water pump

- Same range of liquid temperature tolerance: -20 ℃~150 ℃.
There are different points between them too:
- Different stages: DG46-50X12 is 12 stages multistage water pump but DG45-80X8 is 8 stages multistage water pump.
- Different number of impellers: the impeller of DG46-50X12 is greater than the number of DG45-80X8.
The different points between DG46-50X12 and DG45-80X8 will impact the pump life and use time.
Here are some advantages of DG45-80X8:
- The stage is less than DG46-50x12, which means DG45-80X8 is more stable.
- The pump length is shorter than DG46-50x12, which means the shaft length is shorter. So it will have a long life. Because the shaft length of DG46-50X12 is longer, its shaft is easy to break.
The only one disadvantage of DG45-80X8 is its price is a little higher than the other one.
After analyzing the different points between DG46-50X12 and DG45-80X8, you can know the advantages of DG45-80X8. From our engineer's perspective, we highly recommend using DG45-80X8 for you.
