button (not shown) squarely engages the valve
seat. Replace the orifice button if required (see
Priming Chamber Removal and Disassembly
for orifice button removal).
If the orifice button was removed, screw the new
orifice button into the linkage bar until fully seated.
Align the hole in the linkage bar with the holes in the
bracket and reinstall the pivot pin. Secure the pivot
pin with the previously removed “e‐clip”.
Adjust the orifice button seating as necessary by
screwing the orifice button into or out of the linkage
bar. Proper adjustment is achieved when the ori
fice button fully seats against the orifice before the
linkage bar on the float bottoms against the
threads on the orifice button. When adjustment is
complete, install and tighten the lock washer and
hex nut securing the orifice button.
Install the strainer (6) and priming valve gasket (4).
Lower the float into the priming chamber (5) and
secure the priming valve with the previously re
moved hardware (2 and 3).
(Figure 5)
Install the baffle and gasket (7 and 8) and use a
sling and suitable lifting device to position the prim
ing chamber assembly on the pump suction spool
(26, Figure 1). Secure the priming chamber as
sembly with the hardware (4 and 5).
Reconnect both the suction piping and the air dis
charge tubing to the priming chamber assembly.
LUBRICATION
Seal Assembly
(Figure 3)
Before starting the pump, remove the air vent and
reducer bushing (9 and 11) and fill the seal cavity
with approximately 220 ounces (6,5 liters) of SAE
No. 30 non‐detergent oil to the middle of the sight
gauges (10)
and maintain it at the middle of the
gauges. Clean and reinstall the air vent and bush
ing. Maintain the oil at this level.
Bearings
(Figure 3)
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauges (10A)
and maintain it at
the middle of the gauges. When lubrication is re
quired, add SAE No. 30 non‐detergent
oil through
the hole for the air vent (11A).
Do not
over‐lubri
cate. Over‐lubrication can cause the bearings to
over‐heat, resulting in premature bearing failure.
Under normal conditions, drain the pedestal once
each year and refill with approximately 84 ounces
(2,5 liters) of clean oil. Change the oil more fre
quently if the pump is operated continuously or in
stalled in an environment with rapid temperature
change.
Monitor the condition of the bearing lubri
cant regularly for evidence of rust or mois
ture condensation. This is especially im
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
