These clearances will result in a bypass flow rate of 3 to 6 gpm at 1220-gpm pump-discharge flow. Static deflection tests were made on the pump shaft used in the water test rig and on the lnconel pump shaft to be used in the final pumps. The information obtained, along with the calculated deflection of the lnconel pump shaft during high- temperature operation, indicated that a top labyrinth 52 seal radial clearance of 0.015 in. should be suffi- cient to prevent rubbing of the impeller hub against the top labyrinth seal. These water tests of the primary NaK pump indi- cate that the pump will meet the head and flow conditions required for the ART. A pump tank gas pressure of 10 psigshould be sufficient to suppress cavitation at the design flow rate and up to a NaK temperature of approximately 138OOF. The design conditions are in the range of minimum volute ,- hydraulic unbalance. LiJ
