jet impellor wear

[whitepointer23]

my vicalen jet is a single stage 10 inch unit, can anyone tell me the specs for impellor clearence. ie: what a new jet clearence is and what the maximum tolerance is.

Typical radial clearance for this size of unit would be ^0,15 to 0,65 mm. The smaller the better, provided the end bearing is ok.

thanks for that. it performs fine but i thought i better measure the clearance to make sure it is in spec. the bearings feel good.
