Hello Sir / Madam,

Could anyone please elaborate on the design basis on which the thrust bearings in an OH2 pump could be located closer to the impeller and the radial bearing farthest from the impeller?

For clarity, please refer to the arrangement in fig2.2c on page11 of the link below. As you know, the bearing arrangement in most pumps are per fig 2.2d. Hence my above question.

Thanks in advance for your time.
