F-1.3) 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 F-1.1. Remove pipe
plug (39) from motor housing (6). 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 five 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 F-1.4. 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 (39) from motor housing (6). 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 five 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.
Seal Chamber (DS Units Only)-
Set unit on its side with fill
plug (44) downward, remove plug (44) and drain all oil from seal
chamber. Apply pipe sealant to pressure gauge assembly and
tighten into hole in outer seal plate (29). Pressurize seal
chamber to 10 P.S.I. and check for leaks as outlined above.
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.
F-1.4) Replacing Oil:
Motor Housing-
Set unit upright and refill with new cooling oil
as per Table 1 (see parts list for amount). Fill to just above motor
as an air space must remain in the top of the motor housing to
compensate for oil expansion (see Fig. 15 or 17). Apply pipe
thread compound to threads of pipe plug (39) then assemble
to motor housing (6).
Important ! - For single phase units, oil level should
be below capacitor
Seal Chamber (DS Units Only)-
Set unit on its side, with plug
(44) upward, and refill with new oil as per Table 1 (see parts list
for amount). Apply pipe thread compound to threads of pipe
plug (44) and assemble to outer seal plate (29).
Warning ! - Do not overfill oil.
Overfilling of motor housing with oil can
create excessive and dangerous hydraulic
pressure which can destroy the pump and create a hazard.
Overfilling oil voids warranty.

F-2) Impeller and Volute Service:
F-2.1) Disassembly and Inspection:
To clean out volute (1) or replace impeller (33), disconnect
power, remove hex bolts (26), and lockwasher (12), vertically
lift motor and seal plate assembly from volute (1) and spacer
ring (31), see Figure 4. Clean out body if necessary. Clean and
examine impeller (33), for pitting or wear and replace if
required, inspect gasket (36) and replace if cut or damaged. If
the impeller (33) needs replacing, place a flat screwdriver in the
slot of the end of the shaft to hold the shaft stationary while
unscrewing the impeller (33).
