Hi,
Anybody knows how to calculate or approximate the axial thrust acting on a centrifugal pump open impeller?
Regards

RE: Axial Thrust
Axial thrust depends of impeller design, i.e. Do you have an impeller with rear vanes?, the calculations are depending of pressure on impeller back side.

RE: Axial Thrust
On the impeller there're back vanes. Not very high i.e about 7/64" and also six balancing holes of 3/8" dia. The impeller outside dia. is 13", it's an open impeller with six vanes. The height of the vanes is 1-1/8". The speed is 1800 rpm. The impeller eye area is 27.6 sq.in. It's a small acid slurry pump and i think the back vanes are designed on this impeller to ensure clearing around the stuffing box area instead of thrust reducing effect on this one.
By the end of the day, I will be able to obtain the outlet and inlet pressure.
With balancing holes is the axial thrust can be neglected?
Thanks!

Impeller type and details,
Impeller dimensions,
TDH, GE,
Ns,
A good calculation method is made in ANSI/HI 1.3-2000,
You can aprox for open impeller
