threads. Position the valve as shown in Figure 2
with the discharge port pointing down.
Final Pump Assembly
(Figure 2)
Install the shaft keys (22, Figure 4) in the keyways
of both shafts and reconnect the power source. Be
sure to install any guards used over the rotating
members.
Do not operate the pump without the
guards in place over the rotating parts.
Exposed rotating parts can catch cloth­
ing, fingers, or tools, causing severe in­
jury to personnel.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Be sure the pump and power source have been
properly lubricated, see LUBRICATION.
Remove the fill cover assembly (29) and fill the
pump casing with clean liquid. Install the fill cover
gasket and cover. Install the clamp bar (30) and se­
cure it with the capscrew (31). Refer to OPERA­
TION, Section C, before putting the pump back
into service.
LUBRICATION
Seal Assembly
(Figure 4)
Before starting the pump, remove the vented plug
(10) and fill the seal cavity with approximately 60
ounces (1,8 liters) SAE No. 30 non‐detergent oil to
the middle of the seal oil level sight gauge (14)
and
maintain it at the middle of the gauge. Clean and
reinstall the vented plug. Maintain the oil at this
level.
NOTE
The white reflector in the sight gauge must be posi­
tioned horizontally to provide proper drainage.
Bearings
(Figure 4)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu­
larly through the bearing cavity oil level sight gauge
(14)
and maintain it at the middle of the gauge.
When lubrication is required, add SAE No. 30 non‐
detergent
oil through the hole for the air vent (12).
Do not over‐lubricate. Over‐lubrication can cause
the bearings to over‐heat, resulting in premature
bearing failure.
NOTE
The white reflector in the sight gauge must be posi­
tioned horizontally to provide proper drainage.
Under normal conditions, drain the bearing hous­
ing once each year and refill with approximately 11
ounces (0,3 liter) 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.
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre­
sentative.
