Dear unidentified person- or whatever - in cyber space.

What, no introduction and no name at signing off? Where have all the manners gone?

The risk of turbulence and the affect at the impeller inlet could be significant, and your suggestion would not normally be entertained. However, as there are no other details as to the type of pump and the impeller material I am going to guess that the material may be a polymer on such a small pump. This type of impeller material is forgiving with respect to cavitation and turbulence; without knowing all the details it is difficult to comment further.

Signing off now, with name. Please call again as we love addressing this style of enquiry, nothing else better to do really.

Cheers,

Robin

The inlet size of the pump is 1" and the suction line is 2" dia. Due
to the space constrain can a long radius elbow be installed directly
with the pump mating flange. If so should the eccentric reducer (2x1)
should be before the elbow or in between the elbow and mating
flange.

Thanks
