A detailed evaluation of the best two centrifugal and reciprocating fluid seal concepts selected in the Task 1 preliminary evaluation was performed. The seal concepts were: (1) hydrostatic orifice compensated pocket floating bushing and (2) hydrostatic tapered bore floating ring. Two different arrangements of the tapered bore floating ring seals for each pump were evaluated. The results indicate that the tapered bore floating ring fluid seals with standard seals on the outboard end have significantly lower total flush fluid leakage than the other concepts for both the centrifugal and reciprocating pump. The slurry side leakage rate is within the three percent of pump flow design goal. The hydrostatic pocket bushing fluid seal slurry side leakage is satisfactory on the centrifugal pump, but exceeds the design goal on the reciprocating pump discharge stroke. The tapered bore floating ring fluid seal concept is recommended for Task 3 due to lower total flush fluid leakage, more practical design, lower initial cost and lower maintenance cost. 20 figs., 2 tabs.
