cure the outboard discharge flange, check valve,
and seat to the inboard discharge flange with the
hardware (5 and 6).
Check the operation of the check valve to ensure
proper seating and free movement.
Clean the mating surfaces of the valve seat (5) and
suction accumulator (10). Position the suction
check valve, valve seat (15) and gasket (16)
against the diaphragm pot (19) with the weights
positioned as shown in Figure 2. Secure with the
hardware (7 and 8).
Check the operation of the check valve to ensure
proper seating and free movement.
Secure the suction accumulator (10) to the dia
phragm pot with the hardware (13 and 14).
Connect the suction and discharge piping as de
scribed in

LUBRICATION
Plunger Rod Assembly
(Figure 3)
The eccentric bearing should be lubricated
thoroughly after each 8 hours of operation.
Failure to do so may cause the bearing to
overheat and fail.
Before attempting to lubricate the plunger rod as
sembly, rotate the eccentric cam until the grease
fittings (15 and 16) can be accessed through the
holes in the eccentric guard (1, Figure 1).
Use a grease gun to apply No. 2 lithium base
grease to the upper lubrication fitting until grease
escapes from the eccentric cap. Lubricate the low
er fitting until grease escapes from the top of the
upper diaphragm plate inside the spring.
Gearbox
(Figure 4)
The gearbox was fully lubricated when shipped
from the factory. Change the oil in a new gearbox at
operating temperature after 100 hours of operation
or four weeks, whichever comes first. To drain the
oil, remove the oil cup (29) and position the pump
and gearbox on its side. After draining, reinstall the
oil cup and flush the case thoroughly with a light oil.
Remove the oil cup and drain the flushing oil. Rein
stall the oil cup.
To lubricate the gearbox, add SAE No. 30 non‐de
tergent oil through the oil cup (29) until the oil level
stabilizes at the middle of the oil cup. Check the oil
regularly and maintain it at this level.
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.
