Pressure Test:
Pumps that have been disassembled, Motor Housing -
If
the pump has been disassembled, the oil should be drained
before a pressure test, as described in section “
Checking
Oil” . Remove pipe plug (36) from motor housing (10). Apply
pipe sealant to pressure gauge assembly and tighten into hole
(See Figure 3). Pressurize motor housing to 10 P.S.I. Use
soap solution around the sealed areas and inspect joints for
“air bubbles”. If, after fi ve minutes, the pressure is still holding
constant, and no “bubbles” are observed, slowly bleed the
pressure and remove the gauge assembly. Replace oil as
described in section “
Replacing Oil” . If the pressure does
not hold, then the leak must be located and repaired.
Pumps that have NOT been disassembled, Motor
Housing -
The pressure test may be done with the oil at its
normal level. Remove pipe plug (36) from motor housing
(10). Apply pipe sealant to pressure gauge assembly and
tighten into hole (See Figure 3). Pressurize motor housing
to 10 P.S.I. Use soap solution around the sealed areas
above the oil level and inspect joints for “air bubbles”. For
sealed areas below the oil level, leaks will seep oil. If, after
fi ve minutes, the pressure is still holding constant, and no
“bubbles”/oil seepage is observed, slowly bleed the pressure
and remove the gauge assembly. If the pressure does not
hold, then the leak must be located and repaired.
CAUTION ! Pressure builds up extremely fast,
increase pressure by “tapping” air nozzle.
Too much pressure will damage seal. DO NOT
exceed 10 P.S.I.
Seal Chamber - Set unit on its side with fi ll plug (36)
downward, remove plug (36) and drain all oil from seal
chamber. Apply pipe sealant to pressure gauge assembly
and tighten into hole in seal plate (6). Pressurize seal
chamber to 10 P.S.I. and check for leaks as outlined
above.
