This pump should receive a routine servicing after
Attention
approximately 1,000 hours of use. Earlier servicing
is required if there is excessive leakage from the top
packing or if pump strokes become faster on one
stroke or the other. The use of Titan Piston Lube
(P/N 314-480) is recommended as an upper packing
lubricant. Do not substitute oil, water, or solvent for
an upper packing lubricant.
