This report covers the third quarter of the third phase of the reciprocating charge pump improvement program. The program was begun in 1982 for the purpose of improving the operating life of packings and plungers used in 300 psig, 300F coal/solvent slurry pumps employed in synthetic fuel generating plants. The testing to be performed during this phase has been modified since the last quarterly report. This test measured the effects of slurry migration past the floating piston seal and the time to wear the packing and plunger beyond the acceptable limit. Table 1 summarizes all testing to date, 456 hours total at this time with 72 hours on 35% slurry. It denotes the valve problems seen with rapid pressure decay when pumping slurry. Throughout this time, 33 specific and different equipment failures and operation problems occurred that delayed the testing
