Remark: It is recommended to pre-assemble the pump without the seal. Shim the pump according to the clearance table to obtain the correct impeller clearance, and thereafter assemble the pump with seal.

Exception: AS 42 and AS 52 (two stage pumps) which have floating impellers (shim free).

11.5.1 Clearances

Defined clearances for AS – range to be shimmed

•A= Behind impeller, Clearance between Impeller and Pump casing

•B= Front of impeller, Clearance between Impeller and Cover

•C= Clearance between, Pump Casing and Cover

To remember:

C clearance is machined, B will be given depending on the shims put under A, Behind impeller, should be correct

If problems occur concentrate on the A clearance it is the most important, if there will be a deviation make sure that it will be at B clearance

If it is other problems please contact Johnson pump or dealer for advice.
